How do i take the random number from a slot machine and use it to accordingly to calculate the wins and losses in C++?

I need to generate 3 random numbers between 2 and 7 and that part is okay. Now my if else statements are not working because I don't know how to use that random value to calculate the winnings. Also for some reason, my else statement which is supposed to be "you lost" is not working because I missed {} when I did not, its right there. And also, I need the program to automatically keep on going in the slot machine until you lose the game and that is not working either.

#include <iostream>

using namespace std;

    std::cout << op1 << endl;
