brute-force search program with C++ -

i new c++. going through tutorial google developer: https://developers.google.com/edu/c++/getting-started

here simple match puzzle brute force search solution: horses cost $10, pigs cost $3, , rabbits $0.50. farmer buys 100 animals $100, how many of each animal did buy?

here code:

#include <iostream> using namespace std;  int main() {     int phorse = 10;     int ppig = 3;     int prabbit = 0.5;     (int = 0; <= 100 / phorse; ++i) {         (int j = 0; j <= ((100 - * phorse) / ppig); ++j) {             int money = (100 - phorse * - ppig * j);             if (prabbit * (100 - - j) == money) {                 cout << "the number of horses are: " << << endl;                 cout << "the number of pigs are: " << j << endl;                 cout << "the number of rabbits are: " << 100 - - j << endl;             }         }     }     return 0; } 

however, giving me ridiculous answers [10 0 90], not correct obviously.

i not figure out problem. idea? in advance.

instead of

int prabbit = 0.5; 

try

double prabbit = 0.5;
