Where is my Linux GNU C or gcc compiler installed?

Q. Where is my GNU C compiler? Where does the GNU C (gcc) compiler reside in the CentOS Linux installation? How do I install if it is not installed by default?

A. Use which command to locate c compiler binary called gcc. Usually it is installed in /usr/bin directory.

Type following command to see Linux C Compiler location:

$ which gccOutput:

/usr/bin/gcc

Display gcc version:

$ gcc -vOutput:
