Write a C++ program to find the mean value of a given number using friend function.

Program Algorithm:
Step 1: Include the header files
Step 2: Declare the class name as base with data members and member functions.
Step 3: The function get () is used to read the 2 inputs from the user.
Step 4: Declare the friend function mean (base ob) inside the class.
Step 5: Outside the class to define the friend function and do the following.
Step 6: Return the mean value (ob.val1+ob.val2)/2 as a float.

Program Code in C++:
class base
int val1,val2;
void get()
cout<<"Enter two values:";
friend float mean(base ob);
float mean(base ob)
return float(ob.val1+ob.val2)/2;
void main()
base obj;
cout<<"\n Mean value is : "<<mean(obj);

Program Output:
Enter two values: 100, 200
Mean Value is: 150
