Solution for Exercise 8-3

ex0803

#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

* It's customary to indent the sole statement belonging to if, but it's not required. Sometimes, especially when the statement is short, they're both combined on the same line:

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

* For readability sake, and until you have a lot of coding under your belt, I recommend keeping if and a sole statement belonging to it on two lines. Further, I recommend using the curly braces to block a single statement until you're comfortable knowing when they're required and when they're optional.
