nembudziya:
ok,thanks but what OS by the handheld portable printers

could you please rephrase your question, can't really understand it

imbless:
Pls can someone help me with the name of softwares I need for c++ programming.

I mean full kit such as,
* the best c++ programming softwares
* compilers and decompilers
* assemblers and deassemblers

I don't really know the full list, but I think somebody could help me out here thanks.

Bro, do you really need all these for c++ programming ?

nembudziya:
I'd like to command a printer to print, whats the command.......

Bro IMO, there is no direct way to output to a printer in c++. Printing is an OS-Dependent Operation.

timmyblast:
Please, how do I save a scanned document in pdf format. i.e pdf extention

You can use foxit pdf reader. if you have this, you just have to send the document as a normal print but specifying FOXIT READER as the printer to use

HoluwadareY:
pls i am new to programming. just started learning [/b]Python[b]. i really need help on functions esp those that return values. how to define it and how to call it. thanks in advance

Bro, don't you think "Google.com" could answer these questions better ?

Oops, you mean you are not allowed to use loops ?

handsomeness:
#2. Repeat the greetings based on the number of character in 'greeting'

Note: i am not a python programmer

For Repetition, your will need a loop

check the code below:


greetings = "HEELO GOOGLE"
numOfChars = len(greetings) # numOfChars = the number of characters in greetings

i = 0
while i < numOfChars:
print greetings # output greetings till i equals numOfChars
i = i + 1

sirdamis:
Write an algorithm to evaluate y=a(b-c)^2/d+2. Let x=a(b-c)^2. Thanks. Write the steps involved

Hello, nairalander programming guru. Please I need help as a beginner in programming on what software,pdf and online resource I need.
I am targeting html,css,java and python. Thanks alot

Do you know how to google ?

MockinJay:
Guys I'm in need of your assistance. I just started learning C. I recently wrote the code below to calculate four figures instantly and also to give out some conditions like if the answer is greater than 5, it should print "Your answer is greater than 5 and positive" else, it prints "Your answer is less than 5". Code is working well but I can't seem to get the else part functioning well, even when , the answer is less than 5, it prints greater than 5.

In Line 16, Remove the Quotes around the Expression.
it should be :
if(sumTotal => 5)

Grime:
Conditional statement. The ternary operator is ?:

my bad, I misread the question.
I have made the necessary correction
Thanks.

cbrass:
$age= 15;

($age<15) ? 'Accept': 'Reject';

Who can explain what this code will do and what's the name of this expression?


Cc jregz craigston

[s] Name: Ternary Operator it is a short-hand notation for writing conditional statements[/s]
oOps, he asked for name of expression not operator's name. Expression name: Conditional Expression

($age<15) ? 'Accept': 'Reject';
the above code will return Accept if age is less than 15 Else it returns Reject

Bros, what have u tried na ??

I guess you are suppose to be on Industrial training now ?

I would suggest you look for friends with similar interest or get a mentor !

@WhiZTiM, dat was a whole lot of nice explanation ! Kudos....

crotonite:
thanks bro!, i think your the best on nl. can i folow, folow you on nl ?








more wisdoms to your bucket of wisdom

you 're welcome bro. Sure you could. Remember: we all are here to share ideas !

choose4me:
Hello, Please help me with java code for a student register application I want to build.. It would be a GUI, where a student inputs his/her matric and the app generates a random question unique to the entered matric number.. If answer is right, it marks student present and vice versa..

Please help me as a matter of urgency..Thanks..

Though i dont do java, but i think your request is not specific enough. Where do you really need help ?, random question generation or program logic ? what have you been able to achieve ?

crotonite:
but what i want is a very flexibly array like the 1d array that i can pass an array of any size of row or column. but it seems the above col is cons. isn't it?


by the way thanks so much

hehe. i am sorry, in c++ you are not allowed to do such. Compiliers need to know at least how wide the column is. ANYWAY, you could go for a VECTOR . It is a good alternative !

crotonite:
//how about passing a 2d array to a function?


//for 1d array array 1 could simply write

void take1DArr( int arr[], int len]{

int i; //do array indexing with var i

while(i < (len-1))

{ //do something magical with array arr[]

}
}//end of func.




//a buggy function that accepts 2d array

void take2DArr( int arr[][]){

// this doesn't compile whatz wrong

}


how is the right way to pass a 2d array to a funtion?

if you work with c++ then you must supply at least the Number of columns when passing a multi-dimensional array to a function. So your options are , either supply both sizes OR only supply the size of the columns

so your code should be like this :
const int cols = 6:
void take2DArr( int arr[][cols]){

// do your array processing here !

}

You better find a way to complete your schooling. Not everyone in school has a sponsor.

Coding is a serious task and time-consuming. The time you invest in learning it can be used in other 'hussles' that will see you through school.

There is no questions of wether it is lucrative, you already know few names that made it big through programming. But the sad truth is they are the lucky few. Majority of programmers are broke How times do you see them advertise for 10k web design on here

It is a risky vocation just like football. We only get to hear the amount the European clubs are paying but no one bothers about the take home pay of an average Nigerian league player...and truly not all career footballers got a chance to play in Europe.

So bro, take programming as a spare-time hobby and not a chosen career at this stage, you can still hit it big if it is your destiny. Most of the big names started this way........just do a little research.

you said it all bro..

Bro BlueMAgnificent, i sight u ! ........

peterincredible:
pls help mee ooo i tried to compile my own wx widget but it taking too much time, much time than i expected my is taking more than 2 hours till the extent i got tired and icancelled the installation pls nairalanders pls help me solve or advice me what to do the qt installation too is a serious matter pls your help is needed pls thanks God bless you all

hehe , Do them first ok ? I wish u well

Jengbetiele:
Thanks so much. All my time as I am 100percent free at the moment!

here is wat i have for u

1) Get a c++ IDE . either CodeBlocks http://www.codeblocks.org/ or Vs studio
2) Get yourself a good c++ book (http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list).

if u would learn better thru visual stuffs, u might prefer some video tutorials on utube (
https://www.youtube.com/watch?v=tvC1WCdV1XU)
3) Get Your Self familiar with StackOverflow http://stackoverflow.com/ and google
4) practice , practice .....Keep coding
5) Feel free to ask for help !

Good luck

how much time are u willing to dedicate to this learning process because its a step by step thing

Jengbetiele:
Can someone help me out, I really wish to learn C++ programming language somebody help...............

we should help u on wat ?

if u would prefer already made , take this:

#include <iostream>
using namespace std;
int main()
{
double fahrenheit;
double celcius;

cout << "\t Enter temperature Value in Fahrenheit " << endl;
cin >> fahrenheit;

// using the formula u gave c=5/9(℉-32)
celcius = (5/9.0) * (fahrenheit - 32); // note d .0 stuff to avoid integer division

cout << "\t Temperature in fahrenheit = " << fahrenheit << endl;
cout << "\t " << fahrenheit << " degree fahrenheit = " << celcius << " degree in celcius " << endl;

return 0;
}
