Let’s Write Code
Now that we have GitHub ready and Git installed, we can start writing code. We will make a simple C++ program that calculates the sum of two numbers.
Create Project
Inside the code
directory we made a few chapters ago, we will create a new directory called CS000
. This will hold our sum.cpp
file.
#include <iostream>
using namespace std;
int main() {
int a = 5;
int b = 10;
int sum = a + b;
cout << "The sum is: " << sum << endl;
return 0;
}
Compile Code
If you are using Dev C++, then you can compile and run the code by clicking the green arrow button in the top right corner of the window. If you are using Visual Studio Code, then you can use G++ to compile the project.
g++ sum.cpp -o sum
After compiling, you will notice that a new .exe
file was created. This is the file you can click to run the program. Your Folder structure should look like this:
code
└── CS000
├── sum.cpp
└── sum.exe
