Question

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. Next, using function overloading,
write a function that achieves the same results.

here is my code, but I keep getting error

.#include <iostream>
#include <string>

using namespace std;

int askNumber(string prompt = 1);

int main()
{
int answer = askNumber("Please enter a number: ");
cout << "The number you entered is: " << answer << "\n\n";

return 0;
}

int askNumber(string prompt)
{
int num;
cout << prompt;
cin >> num;
return num;
}

I know the default argument in the parameter there (string prompt = 1) is illegal. I've tried different codes, this one brings less errors than others i've tried. What am I supposed to do?

You simply need to use
int askNumber(string prompt = "generic prompt")
