Answer 1

Answer:

//C program to allocate a memory until no memory is available.

//Allocates memory from swap area when no memory is available.

#include<stdio.h>

//Header file for malloc ( method used to dynamically allocate a single large block of memory with the specified size)

#include<malloc.h>

int main(){

//Declare a pointer to store address of memory allocated

int *memory_allocator;

//while loop will be executed infinite time

while(1){

/Allocate a memory every time loop executes ,memory will be allocated until no memory is available

memory_allocator=(int *)malloc(sizeof(int));

}

return 0;

}
