MCSR

Before using the Intel C compiler, you will need to setup your environment correctly. Once you have done that, you can compile by using the following commands:
icc -o program_name program_name.c (for C)
icc -o program_name program_name.cpp (for C++)

You can get more information about using the Intel compiler by running:
icc --help

GNU Compiler

To compile with GCC, run:
gcc -o program_name program_name.c (for C)
g++ -o program_name program_name.cpp (for C++)

Executing a compiled program

After compiling your program with either compiler, the program can then be executed using the command:
./program_name
