Question

In this lab, you will implement your own dynamic memory allocator (heap manager) in C. We will use the simple (but somewhat inefficient) free list system of heap allocation. You will demonstrate how to use your allocator to allocate dynamic memory for a variety of C types.

Answer 1

Answer:

#include <stdio.h>

#include <stdlib.h>

 

int main()

{

   int *iVar;

   char *cVar;

   float *fVar;

     

   /*allocating memory dynamically*/

     

   iVar=(int*)malloc(1*sizeof(int));

   cVar=(char*)malloc(1*sizeof(char));

   fVar=(float*)malloc(1*sizeof(float));

     

   printf("Enter integer value: ");

   scanf("%d",iVar);

     

   printf("Enter character value: ");

   scanf(" %c",cVar);

     

   printf("Enter float value: ");

   scanf("%f",fVar);

     

   printf("Inputted value are: %d, %c, %.2f\n",*iVar,*cVar,*fVar);

     

   /*free allocated memory*/

   free(iVar);

   free(cVar);

   free(fVar);

 

   return 0;
