Someone run through this and explain why C++(Reset explained in the body of the question)

Question

A Im getting random crazy numbers for a simple solution

B Im getting more than two bowls per frame

#include <iostream>
#include <ctime>
#include <cstdlib>
#include <string>

using namespace std;
    

int bowl()
