write a program to allocate the memory dynamically using malloc.

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
int main()
{
int i,n;
int *ptr;
printf("enter the no. of elements\n");
scanf("%d",&n);
ptr=(int*)malloc(n*sizeof(int));
printf("memory allocated\n");
for(i=0;i<n;i++)
{
ptr[i]=i+1;
}
printf("elements in the array are\n");
for(i=0;i<n;i++)
{
printf("%d\n",ptr[i]);
}
return 0;
}
