Assignment 2 Question 6

I see no one has asked for help or had trouble with Assignment 2 Question 6. Has everyone else completed it no problem and am I just useless???
I can't make heads or tails of it [/img]

Have a look at section 6.14 in Cohoon and Davidson. The recursive function we needed to write is very similar.

* Scratches around for the text book * Dunno if i bought it though... it Was kinda expensive...

Here is the code for the simplest of all the questions.

#include <iostream>
#include <string>
using namespace std;

int gcd(int m,int n) {
if ((m % n) = 0) //evaluates whether m can be divided by n without a remainder then n is the gcd
return n;
else
return gcd(n,(m % n)); //use the c++ bult in function to return the gcd for u if you read the section on recursive functions you will have known this

}

int main() {
int m, n;
cout << "Please enter two integers: " << endl;
cin >> m >> n;
cout << " Greatest common divisor for " << m << " / " << " n " <<
" is: " << gcd(m,n) << endl;
return 0;
}

Please no insult, but gcd you were thought in std 7 or 8 I think can't remember. Now just code it, it is simple.

You're probably gonna need to shell out for the textbook at some point. The study guide doesn't cover most of the material, it just tells you what to read in the textbook.

I had never touched C++ before starting COS111 & COS112 this year, and the textbook has been a lifesaver! That and the COS111 study guide.

Damn. I didnt purchase the text book. Is it possible to pass the end year exam with just the Study Guide from Unisa?

Thanks Guys
