Solution for Exercise 8-17

ex0817

#include <stdio.h>

int main()
{
    int code;

    printf("Enter the error code (1-3): ");
    scanf("%d",&code);

    switch(code)
    {
        case 1:
            puts("Drive Fault, not your fault.");
            break;
        case 2:
            puts("Illegal format, call a lawyer.");
            break;
        case 3:
            puts("Bad filename, spank it.");
            break;
        default:
            puts("That's not 1, 2, or 3");
    }
    return(0);
}

Notes

* The item specified by switch must be a single value. It cannot be a string or anything other than a single value. Functions that return a single value are okay, but a comparison or logical expression doesn't belong.

* A case statement specifies a single value which is compared with the item in the parentheses after switch. Single characters can be specified, in which case they're enclosed in single quotes.

* The break statement is not required. If it's omitted, execution falls through to the next case statement.

* The default item doesn't need a break statement as it's the last item in the structure.

* The default statement can be blank. Heck, a case statement can be blank as well.
