Exercise 1 #

Let’s get used to the rules of implicit type casts by arithmetic operations. Call the add function that we studied earlier with different arguments and ask for the return type of each operation with typeid.

Here are a few examples:

std::cout << typeid( add(1, false) ).name() << std::endl; 
std::cout << typeid( add('a', 1) ).name() << std::endl; 
std::cout << typeid( add(false, false) ).name() << std::endl; 
std::cout << typeid( add(true, 3.14) ).name() << std::endl; 
std::cout << typeid( add(1, 4.0) ).name() << std::endl;
