Correcting Code

The following example contains a coding error: the function returns the maximum value instead of the minimum value:

1 int minimum (int a, int b)

2 {

3 int result; /* Return the minimum */

4 if (a < b)

5 result = b;

6 else

7 result = a;

8 return (result);

9 }

Correct this error by adding the following code to an eval point at line 4:

if (a < b) goto 7; else goto 5;

This effectively replaces the if statement on line 4 with the code in the eval point.
