#include <stdio.h>

int main()
{
    int a,b,larger;

    printf("Enter value A: ");
    scanf("%d",&a);
    printf("Enter different value B: ");
    scanf("%d",&b);

    larger = (a > b) ? a : b;
    printf("Value %d is larger.\n",larger);
    return(0);
}

Notes

* Some programmers prefer ?: because it's cryptic.

* Fortunately, only a few situations exist where the ternary structure is really the best way to make a decision. An example can be found in the book in Chapter 17.

* If the ?: thing frustrates you, then you can generally construct a handy if-else structure to replace it. Even so, be aware that the ?: thing is one of those aspects of the C language that's heavily borrowed by other languages. It may come back to haunt you!
