Write A C++ Program To Find Average Of N Numbers.

#include<iostream.h> 
 #include<conio.h> 
 void main ( ) 
 { 
       int n, a[50], i, s; 
       float av; 
       clrscr(); 
       cout<<"\n Enter the Value of n : "; 
       cin>>n; 
       cout<<"\n Enter the Different "<<n<<" Values : "; 
       for (i = 0; i < n; i++) 
          { 
                cin>>a[i]; 
          } 
                s=0; 
                 for(i=0; i<n; i++) 
                     { 
                           s=s+a[i]; 
                     } 
                           cout<<"\nSum of  " <<n <<" Value is : " <<s; 
                           av=(float)s/n; 
                           cout<<"\nAverage of "<<n <<" Value is : "<<av; 
                           getche();
