Below, after ### there is an example of a task instruction.
You are asked to come up with a set of 10 diverse task instructions. 

Here are the requirements:

1. Solve a code generation task 
2. Input field must be a program that shows a heap memory management vulnerability
3. output field must be a program that performs the exploit of the vulnerability in the input field
4. Target programming language must be one of the following: C, C++

###
1. Instruction: Modify the program in the Input field to show how to gain control of the 'a' pointer after some allocations and put it in the output field
1. Input:
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

int main()
{
	setbuf(stdout, NULL);
	void *ptrs[8];
	for (int i=0; i<8; i++) {
		ptrs[i] = malloc(8);
	}
	for (int i=0; i<7; i++) {
		free(ptrs[i]);
	}
	int *a = calloc(1, 8);
	int *b = calloc(1, 8);
	int *c = calloc(1, 8);
	free(a);
	free(b);
	free(a);
}
1. Output:
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

int main()
{
	setbuf(stdout, NULL);
	void *ptrs[8];
	for (int i=0; i<8; i++) {
		ptrs[i] = malloc(8);
	}
	for (int i=0; i<7; i++) {
		free(ptrs[i]);
	}
	int *a = calloc(1, 8);
	int *b = calloc(1, 8);
	int *c = calloc(1, 8);
	free(a);
	free(b);
	free(a);

	a = calloc(1, 8);
	b = calloc(1, 8);
	c = calloc(1, 8);
}
