u are really a life saver bro. I comment only when I see d need to. I have really seen d need in did thread. thumps up

Bro, do you do php?

Ezechinwa:

hey guys, sorry for keeping you waiting i was really busy... so lets head back to business...

note: after we complete this tutorial on cpp, i will make the pdf file available for download.... i will also design an andriod app where u can extract codes... and execute them... .. isn't that what friends are for?

today we will discuss on conditional statements.. what we have been writing so far, are just simple programs... lets dig into what cpp has to offer... before i proceed I want to thank you guys sharing, commenting , liking , replying.. that's really nice.. i hope to meet you guys someday..

back to business..

We are going to design programs capable of controlling program flow( in program flow, i mean making decisions).. take for instance, your driving on a busy Lagos road.. imaging a situation where the traffic light only had a green signal...?( that would be disastrous wouldn't it?..) but with the help of the red, and yellow light, cars can move in a controlled order. so, guys learn to obey that traffic light, programmers obey the rules don't they?... lol..

now you get the gist, don't you?...

the first item on our menu is using the ''IF'' then '' ELSE'' statement to control the flow of our program..

look carefully, this format goes like this:

if ( condition)
{
// this is what you should do, if the condition above is true
}

else
{
// this is what you should do if the condition above is not true..
}

.. lets try out an example about what i mean...

Example..

consider two variables.. lets name them ''case1'' and ''case2''...... these variables are numbers.. we are to test the magnitude of this numbers ( using a comparative sign..( in this case let's a simple > sign)..

see what happens below....

solution...

// TESTING THE MAGNITUDE OF TWO VARIABLES

// declare our header files

#include <cstdio>
#include <cstdlib>
#include <iostream>

using namespace std;
int main()

{
// declare variables
int case1;
int case2;
int difference12; // difference between (case1-case2)
int difference21; // difference between (case2-case1)

// get questions and answers from the user
cout<<" Welcome sir/ma, kindly enter your first number for case1";
cin >> case1;

cout <<''Welcome sir/ma, kindly enter your second number for case2;
cin>> case2;

// perform so mathematical operations

difference12= case1-case2; // stating the gap between case1 and case2

difference21= case2-case1; //stating the gap between case2 and case1

// now, define the program flow
if ( case1 > case2) // don't add semi colon because its just a condition not a statement.. take note...
{

cout << '' the first number you entered is greater than the second number and by '';
cout << difference12;

}
else
{
cout <<'' the second number you entered is greater than the first number and by'';
cout << difference21;
}

// wait until user is ready before terminating program

system (''PAUSE'');
return 0;

}

OP. ur d best..... THNKS

Ezechinwa:


let me explain what happened above...... unlike other programs we have done so far, this one gets to a point where it has to make a decision on where to go... if the condition where to be true, it will perform operations within the ''if {}'' , but if false, it does the other in the ''else {}''..

so you see, i wont rush this on you and just move on, it is important you understand the decision making techniques... so i will take more examples., but after you guys read and comment on the first one.........

Project::: After more examples on ''IF & ELSE'', we are then going to create a program that can calculate the GPA (grade point) of a student....... you guys can kindly list the units and courses we can use for this project...... thank you and good night..

shares.. comments... replies. etc are very important...... let's build Nigeria....

Ezechinwa:
hello great minds... we are back again , what you saw in my previous posts were programs that can't make decisions...

so, later on today, i will show you how to develop programs that can make decision...

i haven't used variable types like boolean & string... so far, i will find problems needing such in future....

so later tonight... we move futher, for now i don't think my boss will find it funny seeing me posting rather dan working.. lol.. so, later guys...

plz ss wats the difference btw #C nd C++

Ezechinwa:


Good day sir. depends on the angle your looking at it from.... all i know is c++ was derived from #C.... both have different ways of defining objects and class.. from my own prospective, C is more like JAVA... unlike C++ that can contain a single class, containing different type of objects........

for the record, the compilation time of c++ is much slower than that of C...... due to their structure........ in a quintessential summary, their main differences lies in their structure of programming..............

thanks.....

EZECHINWA PLS WHEN ARE WE GOING TO WORK ON THE GP PROJECT?THATS VERY AWESOME

codemarshal08:

Do u Mean to say c# or C
For the Latter, C programming Language is a procedural language i.e it does not support the use of classes, polymorphism etc. WHILE C++ is an Object Oriented Language. Hence, it supports objects, classes , polymorphism etc

classiclee:
Bro am going on with this topic and I love this post am getting confused somewhere on Like Java when we want to echo someting we say
System.out.print("Hello sir/ma";
Does that mean that in C++
It is cout<<"Hello sir/ma"<<endl;
Is this an input type or echo
Because am noticing you run this cout in the ways
cout<<"Hello sir/ma"<<endl;
cout<<"Hello sir/ma";
cout<<"Hello sir/ma case1;
Sorry God Bless you as you help me out

classiclee:
Yea Bro Did you believe in the topic review today I went on google and learnt more I understood things like this
#include <iostream>
#include <string>
//instead of using namespace std
calc(int a,int b)
{
int c;
a=a*b;
c=a+b;
return(c);
}
int main()
{
string abbey="Abiodun";
std::cout<<"Hello sir ma my name is \n "<<abbey;
/*it. Prints hello sir and goes to next line
Right It seems am learning than my brain */
//now executing else
void echo=(3==3) ? "It is true" : "It is false";
std::cout<<echo;
calc(1,2);
//result should be 4
}
Any error help me out I just started 3hours ago...

Hello guys.....
how did your weekend go? well, if you ask me about mine, i will boldly tell you that i had a splendid weekend...... a win for Chelseafc also spiced it up.. so, am going to use a blue text format..

in the last post, i showed you a program capable of making decision and also i gave a detailed illustration using the traffic light, well, before i proceed, it is important you understand what a conditional statement is, or how it works.

Conditional statement in cpp compares two or more objects..... it mostly use the following signs ,namely

> greater than,
<less than,
<= less than or equal to
>= greater than or equal to
!= not equal to

and many more......

for example
condition1 and condition2

IF ( condition1 >= condition2)
{}
ELSE
{}... you see what i mean right?



for more you can always search on-line .... but always remember what conditional statement are and how to run a test on them..........

PROJECT;;;

Write a simple program on cplusplus capable of determining a students grade point avarage (gpa)... use the following information

Grading system =( A=5 , B=4, C=3 , D =2 , E=1, F=0)
GPA system; 5.0
Department : Computer science
Level ; 400 level
Courses offered and unit:

1 Operations research = Mth 401 (3-unit)
2 Numerical analysis = Mth 421 (3-unit)
3 Programming = Csc 401 (3-unit)
4 Database = Csc 411 (3 unit)
5 Computer and society = Csc 421 (3 unit)
6 Algorithm = CSC 431 ( 3 unit)
7 Oracle = Csc 441 (3 unit)

total unit = 21.

wow...... with the following information, lets break them down together........ lets use our programming skills to solve real life programs....

before we proceed...... lets get more comments, more shares , more questions......... thank you and stay tuned...

this lovely mehn would trying using ur idea to write a similar program using VB.NET

Am really following before You go futher Were does c++ Codes get inserted is it in code.c or how and how to compile it to an app for we to make our practicals our selves
