1:What's wrong with this program? 
int main(void)
{
   int * fp;

2:What would the following program do? (Macintosh users can assume the program correctly uses console.h and the ccommand() function.) 
#include <stdio.h>
#include <stdlib.h>

         exit(1);
    while ( (ch= getc(fp)) != EOF )

fp2 = fopen("jerky", "w");
