How to Edit, Compile, and Execute a C++ Program?
Create a new cpp file using your text editor. Enter the following in it −
#include<iostream>
int main() {
std::cout << "Hello world";
}Save this file as source.cpp.
Once you've got your compiler and source program ready, it is very easy to compile and run a C++ program. Assuming that you've installed GCC compiler, and you have a source.cpp file that you want to compile, follow the following instructions to compile and run it.
Open a new terminal window or cmd if you are on windows.
Change the directory to the directory in which you have your source.cpp file. For example, if it is in C:/Users/Dell/Documents, enter your command line −
$ cd 'C:/Users/Dell/Documents'
Now enter the following command to compile the source file using g++.
$ g++ -o <name-you-want-to-give> source.cpp
In place of <name-you-want-to-give> replace it by any name like myprogram, etc.
Run it! Now you can run the program using −
$ ./myprogram
