C++ Program to concept of function overloading with different data type

Program -

#include<iostream.h>

#include<conio.h>

int average(int a,int b,int c);

void main()

{

clrscr();

int a,b,c;

int average(int,int,int);

cout<<"enter the integer values:"<<endl;

cin>>a>>b>>c;

cout<<"a="<<a<<"b="<<b<<"c="<<c;

average(a,b,c);

cout<<endl;

getch();

}

int average(int a,int b,int c)

{

int av;

av=(a+b+c)/3;

cout<<"\n average of three integer no is:"<<av<<endl;

return(av);

}

Output - 

enter the integer values:

6 8 4

a=6b=8c=4

average of three integer no is:6
