Create a program that prompts the user to enter a number (from 1-3000 only) then output the number and its corresponding roman numeral number.

[2] 12Hr clock  24Hr clock
Create a program that will prompt the user to input time based on a 12-hour clock and output the corresponding time based on a 24-hour clock. Check all possible invalid input data.

Re: Switch Statement Problem

Code:

printf("[display menu]");

char buf[32];

fgets(buf,30,stdin);

switch (atoi(buf))

{

case 1: /* do the 1 stuff */ break;

case 2: /* do the 2 stuff */ break;

case 3: /* do the 3 stuff */ break;

default: printf("INVALID\n"); break;

}
