#include <stdio.h>

#include <stdlib.h>

  

int main()

{

  

    // This pointer will hold the

    // base address of the block created

    int* ptr;

    int n, i;

  

    // Get the number of elements for the array

    printf("Enter number of elements:");

    scanf("%d",&n);

    printf("Entered number of elements: %d\n", n);

  

    // Dynamically allocate memory using malloc()

    ptr = (int*)malloc(n * sizeof(int));

  

    // Check if the memory has been successfully

    // allocated by malloc or not

    if (ptr == NULL) {

        printf("Memory not allocated.\n");

        exit(0);

    }

    else {

  

        // Memory has been successfully allocated

        printf("Memory successfully allocated using malloc.\n");

  

        // Get the elements of the array

        for (i = 0; i < n; ++i) {

            ptr[i] = i + 1;

        }

  

        // Print the elements of the array

        printf("The elements of the array are: ");

        for (i = 0; i < n; ++i) {

            printf("%d, ", ptr[i]);

        }

    }

  

    return 0;

}

Enter number of elements: 10
Memory successfully allocated using malloc.
The elements of the array are: 1, 2, 3, 4, 5,6,7,8,9,10
