I've started to learn C++ and I'm reading this book (in the title).
I got stuck in this exercise.
I've done half of it but I can't clearly understand what it's asking me to do next
This is what the exercise says:
Using default arguments, write a function that asks the user for a number and returns that number. The function should accept a string prompt from the calling code. If the caller doesn't supply a string for the prompt, the function should use a generic prompt.(until here I understand)
Next, using function overloading, write a function that achieves the same results.
How could I make an overloaded function to make the same thing?
I thought (perhaps wrong) that overloaded functions were only created to handle different types of data (int, string, bool...)
This is what I've done:
using namespace std;
string userInput(string prompt = "Please enter a number: ");
string input1 = userInput();
cout \<\< input1 \<\< " - This is what you've entered 1st.\n\n";
string userInput(string prompt)
cout \<\< prompt;
cin >> number;
