Write a program that compute this formula: s^2 + p *(s - x) * (p + y) in C++

Given the following pseudocode, write a program that executes it. Use floating-point types for all values.
read x;
 read y;
 compute p = x * y;
 compute s = x + y;
Total = s^2 + p *(s - x) * (p + y);
 print total.  

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

#include <iostream.h> #include <conio.h> int main () { float x, y, p, s, s2, Total; cout << " Enter a value of x? \n"; cin >> x; cout << " Enter a value of y? \n"; cin >> y; p = x * y; s = x + y; s2 = s * s; Total = s2 + (p * ((s - x) * (p + y))); cout << " s = x + y; p = x * y \n"; cout << "\n s^2 + (p * ((s - x) * (p + y))) = " << Total ; getch (); return 0; }// main

Result:

 Enter a value of x? 
2
 Enter a value of y? 
5
 s = x + y; p = x * y 

 s^2 + (p * ((s - x) * (p + y))) = 7999
