What is C++?


If you haven't heard of c++, c++ is a general purpose language designed by Bjarne Stroustrup. C++ is object oriented and can be used to create almost all applications for desktop or mobile NDK. Since c++ is a bit closer to low level language it is usually called a middle level language. And yes c++ can be used in embeded system and game development.


C++ simply means C +1.



Board is open for all the citizens of C/C++ Republic.

WHY C++ IS THE RIGHT CHOICE


1. You can do everything with c++


Just think about that thing you wanna do with a programming language, c++ will do it with efficiency. From desktop apps, mobile apps, game development, embeded system, web apps like facebook, e.t.c


2. VERY FAST
Yes! since c++ is compiled and not interpreted, and also translated to assembly makes it the right choice when performance is the theme of the day!!

we are with you

welcome bro, i'm a beginner. What about you?

Nice thread!
You should consider posting some interesting questions or challenges so as to keep the thread 'warm' and interactive.

Welcome bro, just what i was thinking.


CHALLENGE 1: CALCULATOR v1


Write a program that helps us calculate addition and subtraction of two given input.


EG. USER chooses an operator like addition (+) then input two numbers like 1 and 3. The computer processes the input and give us 4.


You can write the code on http://ideone.com and share the link.

Gosh I love c++, I did it last year when I was in 200l, syntax so beautiful
#include <iostream> Using namespace std;
int main() { return 0; }
Gosh, but no time to code c++ again, java already got my soul

lol, welcome bro. Java?? maybe when i'm done learning cplusbae. Java dey scatter my brain but c++ just dey flow like fresh water.

I'm still at the beginners level in java, but I know what my codes can do....

At first, last year december to be precise, I saw one java syntax and it scared the shit outta me, I started android dev january this year, right now, you'd be amazed with what I have done, not bragging tho
.
.
So don't be scared, java is fun especially if you have an awesome IDE
.
.
Back to c++, what project do you think needs c++? Just pick up a big(not too big) c++ project and start executing, the more you get the work done, the more you learn c++, that was how I learn java

Yea thanks, Java has you paint it is okay, infact most programmers in Nigeria focus on Java but i'll learn java when i want to dive into android. As for now, i'm focusing on game development. Java can also be used but performance is important to me. I might even learn c#(looks like java), python before java. Like i said, i'll learn Java when i want to dive into android.


What big project can you suggest? i'll like to try em. I don't mind if it's android, i'll use ndk for it.

A big project can be anything, just think of something and start, my first android app was a game, not with too much graphics oh, just a small logical game, it took me 6months to get it 80% done, that was how I learn what java is all about, you too can just think of a game you can do with c++, on any platform and you'll see how fast you will learn

I'll try that. Thanks brother.

3. IDEAL FOR COMPETITIVE PROGRAMMING
Cause of its fastness, most competitive programmers recommend c++ as the go-to language when participating in the sport.

Thanks brother for that comment, are you a c++ programmer? if yes, your input will be appreciated sir.

I'm having problem using that online compiler but here is my code

I can't find the code.

For the online compiler, make sure you select c++11 as your language.

//The program does simple calculations like add and sub
#include <iostream>
#include <cstdlib>
using std::cout;
using std::cin;

int dosum(int a,int b);
int dosub(int a,int b);


int main()
{
char ans;
int a,b;

cout<<"What type of operation do wish to perform? enter a for additions or s for subtraction\n";
cin>>ans;
if(ans!='a'&& ans!='s')
{
cout<<"You entered the wrong answer for the opration to be performed\n";

exit(1); /*the program exits if the user enters a wrong specification for operation*/
}
cout<<"Input the two numbers\n";
cin>>a, cin>>b;


if (ans=='a'||ans=='A')
{
cout<<"The sum of the two numbers entered is "<<dosum(a,b)<<" \n";
}
else if(ans=='s'||ans=='S')
{
cout<<"The difference of the two numbers is "<<dosub(a,b)<<" \n";
}

return 0;
}

int dosum(int a,int b)
{
return a+b;
}

int dosub(int a,int b)
{
return a-b;
}

Where does it run? Any best IDE for it?

I'm using cppdroid....

@ibromodzi,
Great code brother, it worked. I would have replied earlier but i was banned.

I used the code to calculate 5-9 and it gave the right answer.

https://ideone.com/5Mb9CY
SUGGESTION: Try replace a and s with + and - respectively.

Any one for Windows Desktop?

No way you use ideone too

lol what'syour point There are lots of c++ library and framework to achieve great gui

check out:

*MFC

*COCOA
Rad

*QT

*wxWidgets

*JUCE


so your point

TobiTobiTobiWhy:
Meaning

u use ideone.com to test your codes right
