How to compile and run the C++ program?

Step 1 − Open a new terminal window or cmd if you are on windows.

Step 2 − 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'

Step 3 − 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.

Step 4 − Run it! Now you can run the program using −

$ ./myprogram
