Sum and avg of array elements

Non-Recursive C Program:

Aim:
To insert a element into array.

Program:
#include<stdio.h>
#include<conio.h>
void main ( )
{
   int A[25],m,i,sum=0;
   float avg;
clrscr();
printf("\nEnter the size of array:");
scant("%d",&m);

printf("\nEntet the Elements:");
  for(i=0;i<m;i++)
    {
       scanf("%d",&A[i]);
     }

printf("\nThe Array is:");
  for(i=0;i<m;i++)
    {
       printf("%3d",A[i]);
     }

for(i=0;i<m;i++)
   {
     sum+ = A[i] ;
   }         
printf("\nThe sum of array Elements is %d",sum);
  avg = sum/m ;
printf("\nThe average of array Elements is %f",avg);
}
