void main()
{
    char notes[15];
    char grd;
 
    printf("Input the grade :");
    scanf("%c", &grd);

    grd = toupper(grd);
    switch(grd)
    {
    case 'E':
        strcpy(notes, " Excellent");
        break;
    case 'V':
        strcpy(notes, " Very Good");
        break;
    case 'G':
        strcpy(notes, " Good ");
        break;
    case 'A':
        strcpy(notes, " Average");
        break;
    case 'F':
        strcpy(notes, " Fails");
        break;
    default :
        strcpy(notes, "Invalid Grade Found. \n");
        break;
    }
    printf("You have chosen  : %s\n", notes);
}

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
