F inding average is one of the simplest programs. Here we input 5 variables, then added together for ‘sum’ and the ‘sum’ is divided by the 5 to produce the average. The Program //program to find average. #include<iostream.h> #include<conio.h> void main() { int i,x,sum=0,avg; clrscr(); cout<<"Enter the 5 elements\n"; for(i=0;i<5;i++)                 {                 cin>>x;                 sum=sum+x;                 } avg=sum/5; cout<<"sum="<<sum; cout<<"avg="<<avg; getch(); } Run the program after compilation.
