Ben Goes back to C++

Before I make an account on a more appropriate forum, I figure I'll try my luck here (besides, I've found that forums are generally hostile towards new members with beginner questions...)

Anyway, I am making a simple program that uses Euclidian method for finding the GCD. Very simple, but I can't get my program to comile. It's a simple error, but my c skills are a bit rusty.

  Code:

#include <iostream> using namespace std; double greatestCommonDivisor(double first, double second); int main () { //variables double first, second; do { cout << "Welcome to Euclid's method for finding the GCD." << endl << "To quit, enter 0 for either number." << endl; cout << "Enter the fist number:"; cin >> first; cout << "Enter the second number:"; cin >> second; greatestCommonDivisor(first, second); } while (first != 0 && second != 0); return 0; } double greatestCommonDivisor(first, second) { if(second == 0) return first; return greatestCommonDivisor(second, first % second); }

I get the error:
gcdc.cpp: In function `int main()':
gcdc.cpp:30: error: expected `;' before '{' token

seems like a missing semicolen, but I don't see it.

Thanks guys.

Not sure. You need to check in the IDE what makes the compiler happy.

Mine complains only about mixed input arguments for greatestCommonDivisor (declared double, but "first % second" appears to require int?). And refuses to build due to "LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt"

I had the int to double error before. I was able to fix it on my end though. Strange it persists for you.

LOL seems I needed only to take a break for a few hours. The problem was obvious: was missing parenthesis around 0 on return (0);

Now I have more syntax errors. grrr

Good luck! )

Ah C++, the language of love.
