## SOURCE CODE : :

```/* C++ Program to Find Sum and Average of three numbers  */

#include<iostream>
using namespace std;

int main()
{
float a,b,c,sum,avg;
cout<<"Enter 1st number :: ";
cin>>a;
cout<<"\nEnter 2nd number :: ";
cin>>b;
cout<<"\nEnter 3rd number :: ";
cin>>c;

sum=a+b+c;

avg=sum/3;

cout<<"\nThe SUM of 3 Numbers [ "<<a<<" + "<<b<<" + "<<c<<" ] = "<<sum<<"\n";
cout<<"\nThe AVERAGE of 3 Numbers [ "<<a<<", "<<b<<", "<<c<<" ] = "<<avg<<"\n";

return 0;
}```
