So I've just gotten started properly in programming now, after playing around with it lightly for far too long and not really learning anything. I'm currently at the end of chapter 5 (of Beginning C++ game programming), and stuck on the last exercise..
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.
Now the code I've written so far is below... But I don't see how, or even what the point would be in rewriting this to allow it to be done with function overloading... Have I stupidly misunderstood the exercise? If so, could someone explain it a bit more clearly. Thank you. #include <iostream> #include <string> using namespace std; int number(string stringInput = "Please enter a number: "); int main() { int firstNum, secondNum; firstNum = number(); cout << firstNum << endl; secondNum = number("Please put your here here -> "); cout << secondNum << endl; return 0; } int number(string stringInput) { int value; cout << stringInput; cin >> value; return value; } [Edited by - Mukunda on April 9, 2007 9:09:21 PM]
