How to run a C program

• Create a c file (filename.c, example hello.c)
• Write some code

    #include<stdio.h>

    int main()
    {
        printf("Hello, world");
        return 0;
    }

• Execute in Terminal

    $ gcc -o hello hello.c
    $./hello

syntax:  gcc -o <filename(whatever you can give)> filename.c

         $ ./hii
