Question

analyze each program and figure out what is wrong with the memory management in the code and how to fix the code.

#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

// Hint: If you run this program repeatedly, with ever-larger numbers as input,
// eventually something (slightly) unexpected should happen.
int
main(int argc, char *argv[])
{
if (argc != 2) {
fprintf(stderr, "usage: broken2 <value>\n");
exit(1);
}
int size = atoi(argv[1]);
int *p;
p = malloc(size*sizeof(int));
for (int i = 0 ; i < size; i++) {
p[i] = i;
}
int *q;
q = malloc(sizeof(p));
for (int i = 0 ; i < size; i++) {
q[i] = p[i];
}

free(p);
free(q);
return 0;
}
