C program to find the sum of all elements in given array

/* Write a C program to read N integers and store them in an array A, and so find the sum of all these elements using pointer. Output the given array and and the computed sum with suitable heading*/

#include <stdio.h>
#include <conio.h>
#include <malloc.h>

void main()
{
  int i,n,sum=0;
  int *a;

  clrscr();

  printf("Enter the size of array A\n");

  a=(int *) malloc(n*sizeof(int));   /*Dynamix Memory Allocation */

  printf("Enter Elements of First List\n");

/*----------------------------
Output
Enter the size of array A
4
Enter Elements of First List
10
20
30
40
