Download the Program

Syntax:
ptr = (cast_type *) malloc(size_in_bytes);


#include<stdio.h>
void main()
{
        int i, n;
        int *arr;

        printf("\nEnter the number of elements: ");
        scanf("%d", &n);

        arr = (int *)malloc(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
