Answer 1

#include <iostream>
#include <string>
using namespace std;
int main(){
    int start = 200, stop = 2000, count = 0, count2 = 0;
    string s;
    cout<<"Enter the two integers\n";
    cin>>start; cin>>stop;
    for(int i = start; i <= stop; i++){
        count = 0;
        s = to_string(i);
        for(int j = 0; j < s.length(); j++) if(s[j] == '3') count++;
        if(count == 3) count2++;
    }
    cout<<count2;
    return 0;
}
