Solution for Exercise 8-1

ex0801

#include <stdio.h>

int main()
{
    int a,b;

    a = 6;
    b = a - 2;

    if( a > b)
    {
        printf("%d is greater than %d\n",a,b);
    }
    return(0);
}

Output

6 is greater than 4

Notes

* Comparisons, or evaluations, are made in code when you can't really predict what the outcome will be. In this example, it's pretty easy to figure out what the result will be. In a more realistic example, the comparison of a and b would be based on input or other conditions unknown at runtime.
