Question

1. (10 pts) Write the code for a simple C program with the following
features (the exact details are completely upto you): (i) main() calls a
function foo() which in turn calls a function bar(), (ii) has a global
variable int *a, and (iii) bar() dynamically allocates an integer and
assigns its address to a. On a time-line, show the contents of the
process address space: (a) just before the dynamic memory allocation
in bar(), (b) just after the dynamic memory allocation in bar(), and
(c) just after bar() returns. Be sure to identify speci c contents within
the frames of the process stack.

Explanation / Answer

Answer:

#include<iostream>

#include<stdio.h>

#include<stack>

using namespace std;

void foo();

int bar();

int*a;

int main()

{

cout<<" Here i m main hey foo i m calling you";

foo();

}

void foo()

{

printf("hi my name is foo hey main i m calling bar");

bar();

}

int bar()

{

int n=10;

cout<<" contents of a "<<10;

a=new int(n);

stack<int>c;

c.push(n);

c.push(n);

bar();

}
