hope u guys av seen a stack class implementation... Well if u av nt seen it b4 u can download the code snippet online. My question is how well and efficiently can i use a vector class in place of a stack.

BlueMagnificent:
Good to learn of your interest in C++
Can u please post the error message you encountered while building your application

my laptop has been down for sumtym now cos we dnt av power supply. For now we can only talk on phone. Thanks

peterincredible:
tanks I will download another one with the Mingw and install it but I want to ask have u designed any application and have you finished with all the topics under the c++ language

how far hav u reached in cpp. Anyway amost done with it. Wel may be shud talk on phone and lets see ways we can help each other to grow. U can cal or chat wit me in whatsapp with 08036407597

What I intend to do is generate and print a report. I intend to design the report with Qt Creator, and then, sort of grab the form and print in A4 size. But I have a feeling I'm not going about it the right way... I saw QPdfWriter mentioned in a couple of places on the web, but can't quite figure it out.

helo gud day, am into c++ programing, for sumtym now i have bin trying to do sum stuff dat involve the use of gui toolkit like wxwidget or qt bt i couldnt use dem. Though i concentrated more on the QT, i tried all i could, to make sure dat the qt work but all to no avail. When ever i compile my codes it keep giving me error. Plz i will be vry vry happy and grateful if u can help me out with the qt.
Plz guys help me. My numb nd my whatsapp numb is: 08036407597

Sup guys.
I have been wondering what are the chances of c++ programmer in the job market.

Most programmer/web developer that I know are employed based on there java,php,.net e.t.c. skills but never c++.

How relevant is c++ in nigeria I.t industry and what hope do c++ job applicant have?

#myopinion.

my felow programa u jz raise an interesting issue. May b u shud gv me ur numb lets discus ds issue in whatsap. Anyway my numb is 08036407597. U can send me a whatsap msg if u wish. Tnks

I want to create a c/c++ program that accepts an unknown set of integers at runtime but I dont want to declare the size of the array or pointer in my program. I want the program to be dynamic enough to resize itself to the user inputs.

I don't want a declaration like a[100] or a = new int[100] or a*int=a*malloc[100], etc because of the lenght 100 (or any other number).

My question is if it is possible for a dataype like integer to read values at runtime with unknown lenght?

am stil having the same problem. I also find it dificut to alocate memory to array of arbitrary set of elements. May b u shud gv ur number so we can discus it more in whatsap. Any way my num is 08036407597. Snd me a whatsap msg. Tnks

asuoka:
Well if you guys can message me ur nos or email addresses am not making it compulsory cause am not really frequent with NL...pls no insult...just opinion cause nigerians main hobby is to insult people at first sight...the no or myb bbm pin is to create groups which will make it faster for communication faster

i really like this thread, i have been looking for stuff like this for a while now. Well am a c++ programmer. This is my contact, u can send me a whatsapp message 08036407597

mnairaland:
okay. I get it. a class to implement a mathematical SET of integers.

my friend i wil realy appreciate if talk on other platform, may be facebok and whatsapp. Plz send me a whatsapp message to my numb( 08036407597 ) my facebuk name is cletus ijeoma onyoke. Or better stil give me ur number and facebuk detail let me send u a message right away. Thanks

mnairaland:
there is a quick sort function in std c library.Why dont u use it.

u might be right but as a programmer who want to reach the peak, you should lok for ways to solve ur problems ursef.
If i may ask, which of the standard lib class wil i get the function to perform the quicksort?

Guys this is the code i wrote to implement this quicksort sorting technique, please lets join hands and analyze the program and looks for ways on how to upgrade the code and make it more efficient, efficient enough to sort array of any elements:

#include <iostream>
using namespace std;
void swap(int *, int *);
void quicksort(int *, int, int);
int partition(int *, int, int);

int main ()
{
int first_index, last_index;
const int size = 10;
int data[size]={30, 70, 5, 10, 75, 81, 23, 41, 93, 53};
first_index = 0; last_index = size-1;
cout << "The unsorted elements are: \n";
for(int i = 0; i < size; ++i)
cout << " " << data[i];
cout << "\n\n";
quicksort(data, first_index, last_index);
cout << "The sorted elements are: \n";
for(int i=0; i<size; ++i)
cout << " " << data[i];
return 0;

}
void swap(int *element1, int *element2)
{
int tempstore;
tempstore = *element1;
*element1 = *element2;
*element2 = tempstore;
}

int partition(int *value, int index1, int index2)
{
while(value[index1]<value[index2])
--index2;
swap(&value[index1], &value[index2]);
while(value[index1]<value[index2])
++index1;
swap(&value[index1], &value[index2]);
while(value[index2]>value[index1])
--index2;
swap(&value[index1], &value[index2]);



return index2;
}

void quicksort(int *aray, int first, int last)
{


int pivot;
/* Termination condition! */
if ( last > first )
{
pivot = partition( aray, first, last );
quicksort( aray, first, pivot-1 );
quicksort( aray, pivot+1, last );
}

}

Hello good day my fellow programmer, i did some coding which i use to sort array of int elements using the quicksort technique. To an extent the program i wrote to implement the sorting using the quicksort worked very well but not that efficient because when i used the program to sort an array that has more than 15 elemnets, the program does give me the desired result that i want.
Here is how quicksort technique works, it has two steps:
1) Partitioning step: take the first element of the unsorted array and determine its final location in the sorted array(i.e,, all values to the left of the element in the array are less than the element, and all values to the right of the element in the array are greater than the element). We now have element in its proper location and two unsorted subarrays.

2) Recursive Step: perform step 1 on each subarray.

Now let me break down the step 1 further so that you will have a broader knowledge of what i am trying to explain. Each time step 1 is perform on a subarray, another element is placed in its final location of the sorted array, and two unsorted arrays are created. When a subarray consists of one element, that array must be sorted; therefore the element is in its final location.
The basic algorithm seem simple enough, but how do we determine the final position of the first element of each subarray? As an example, consider the following set of values (the element in bold is the partitioning element__it will be placed in its final location in the sorted array):
37 2 6 4 89 8 10 12 68 45

a) Starting from the rightmost element of the array, compare each element with 37 until an element less than 37 is founnd. Then swap 37 and that element. The first element less than 37 is 12, so 37 and 12 are swapped. The values now reside in the arrays as follow:
12 2 6 4 89 8 10 37 68 45

b) Starting from the left of the array, but beginning with the element after 12, compare each element with 37 until
an element greater than 37 is found. Then swap 37 and that element. The first element greater than 37 is 89, so 37 and 89 are swapped. The values now reside in the array as follow:
12 2 6 4 37 8 10 89 68 45

c) Starting from the right, but beginning with the element before 89, compare each element with 37 until an element less tha 37 is found. Then swap 37 and that element. the first element less than 37 is 10, so 37 and 10 are swapped. The values now reside in the array as follows:
12 2 6 4 10 8 37 89 68 45

d) Starting from the left, but with the element after 10, compare each element with 37 until an element greater than 37 is found, then swap 37 and that element. There ar no more elements greater than 37, so when we compare 37 with itself, we know that 37 has been placed in its final location of the sorted array.

Once the partition has been applied to the array, there are two unsorted subarrays. The subarray with values less than 37 contains 12, 2, 6, 4, 10, and 8. The subarray with values greater than 37 contains 89, 68 and 45. The sort continues with both subarrays being partitioned in the same manner as the original array.
Based on the preceding discussion write recursive function quicksort to sort a single sub-scripted integer array. the function should receive as arguments an integer array, a starting subscript and an ending subscript. Function partition should be called by quicksort to perform the partitioning steps

tanks 4 dropping ur numb. Lets talk more on whatsapp. I wil stil b grateful if oda programmers apart from c++ e.g java nd c drop their number cos i strongly believe that we can stil be useful to each oda. Tanks

Am a c++ programmer, though i have not really gone far into it. But i have understood every bit of c++ code i have learnt. I have longed wish to hook up with other like-minded programmers so we can share ideas. Well i wil b thankful if u guys drop ur phone numbers, so we can interact beta on other platform like whatsapp and facebook. My numb is 08036407597.

Helo @blue magnificient, tanks for creating this thrend, i av bin following al ur programin post on nairaland, u ar rly doin a great job. Mor greaze to ur elbow. Am learnin c++, i av downloaded most of d c++ ebooks, i even bought a hardcopy textbook nd i must tel u dat it has bein an interesting experience. The only prob am avin is dat i am learnin it on my own so sumtyms i fil am not getin any challenge, and it takes me time to digest sum complex topic. Plz if u dnt mind giv me ur numb so dat i can be seeking ur help wen i nid 1. Tanks

The super eagles are really improving, their sytle of play has changed immensely but we still need to work on some of our news players cos they lack focus and inexperience. When you look at the second goal that torres scored, it was the inexperience of obabono that lead to that goal, becos he was suppose to be at the front of torres even before the ball was crossed but instead he was looking at the ball forgetting that torres was very close to him. As a defender ur eyes are suppose to be on both the ball and the nearest opponent close to u, But no doubt the guy is a good and feature player. Musa should also learn how to control his pace and how to giv pin point pass.
God bless super eagles
