C-programming - Installing c on linux os, Gcc install on linux

Installing c on linux os

It was difficult to install C in olden days, but no it has become very easy to
install c / c++ compiler. GCC stands for GNU Compiler Collection. And it contains compilers for various languages such as C,C++,Java and so on. It is one of the most efficient free implementation of a compiler one can hope to get ones hands on and is available for multiple platforms and OSes including Windows.

To find what version of gcc is installed on your machine, type the below command

 # gcc -v

If the gcc is package is already present it will print the gcc version or else
it will start installing the gcc and will install the package as below.

output:
[root@localhost]# gcc -v
bash: gcc: command not found...
