This is pretty easy once you know how to distinguish it and analyze the problem. I'll even have it show some text like "ODD" and "EVEN" for you...


Code:
#include <stdio.h>

int main(void)
{
     int input;
     char strings[1][5];
     
     strcpy(strings[0], "ODD\0");
     strcpy(strings[1], "EVEN\0");

     printf("Give me a number: ");
     scanf("%i", &input);

     printf("This is a(n) %s number!", &strings[(input+1)%2]);

     getch();
     return 0;
}
