#include <iostream>
using namespace std;

int main () {
    int  a = 5;
    int  b = 10;
    char c = 'c';
    char d = 'd';
    bool t = true;
    bool f = false;

    cout << "int + int = "   << (a + b) << endl;
    cout << "char + char = " << (c + d) << endl;
    cout << "int + char = "  << (a + c) << endl;
    cout << "bool + bool = " << (t + f) << endl;
    cout << "int + char + bool = " << (a + c + t) << endl;
    return 0;
