Download the Program

Syntax:

ptr = (cast_type  *) calloc (number_of_blocks, size_in_bytes);

#include<stdio.h>

void main()

{

    int i,n;

    int *arr;

    printf("\nEnter the number of elements: ");

    scanf("%d", &n);

    arr = (int *)calloc(n, sizeof(int));

    if(arr == NULL)

    {

        printf("\nInsufficient memory allocation");

        exit(0);

    }

    printf("\nEnter the array elements: ");

    for(i=0; i<n; i++)

        scanf("%d", (arr+i));

    printf("\nThe array elements are: ");

    for(i=0; i<n; i++)

        printf("%d ", *(arr+i));

     free(arr);

}

Output:

Enter the number of elements: 5

Enter the array elements: 11    22     33    44    55

The array elements are: 11    22    33    44    55
