    A global variable is a variable which is defined outside all functions. Hope the example explains:

    Code:
    #include <stdio.h>
    
    int global_var = 5;
    
    int main ()
    {
        printf ("Global variable global_var has value %d\n", global_var);
        return 0;
    }
    A variable declared in a function is only known by that function and therefore called local.
