Can someone help me out here? I have a bunch of test statements in the
program and my test printf("Do I have trouble here after
GetNumbers()?\n"); does not display rather I get garbage. Please help.
#include <stdio.h>
#include <system.h>

int arrNumb[10]; /* user input into array */
int *parrNumb; /* pointer to array */
int i=0; /* used as a counter in array */
for (i=0; i<10; i++) /* initialize array to 0's */
arrNumb[i] = 0;
//display the title of the program
quitNow = DisplayTitle();
if (quitNow=='Q' || quitNow=='q')
{
return 0;
}
//printf("Do I have trouble here before GetNumbers()?\n");
//Get all 10 numbers from user
GetNumbers(arrNumb[10]);
printf("Do I have trouble here after GetNumbers()?\n");
//Find minimum number in array

printf("\nmin is: %i",min);
//Find maximum number in array

printf("Do I have trouble here before DisplayNumbers()?\n");
//display the output
