I've tried implementing a couple different changes, but had no success. I have about 2 hours left before I have to submit the program. If anyone can help me understand my mistake, I would greatly appreciate it.
Code:

#include <stdio.h> // for input/output
#include <time.h> // to use the internal system clock for random number generation
#include <stdlib.h> // to use the random number generator
#define MAXGUESSES 6
#define MAXGAMES 20
#define MAXNUMBER 100
//function prototypes
