Hi,
Can someone help me with an idea on how to start writing a C++ code
for generating
greatest common divisor and the linear combination of two intergers
represented as gcd(m, n)= mx + ny and adding them it will give us the
greatest common divisor and I need to use the extended Euclidean
algorithm.
I already have the code for the greatest common divisor but I dont
know how to do the linear combination.
This is what I have:
#include <iostream>
#include <iomanip>
using namespace std;
void gcd(int, int);
void extended_gcd(in t, int, int, int);
int main()
{
int m=0, n=0;
cout<<"Welcome to the Greatest Common Divisor Program\n\n";
cout<<"Enter the first number: ";
cin>>m;
cout<<endl;
cout<<"Enter the second number: ";
cin>>n;
cout<<endl;
cout<<"gcd("<<m <<", "<<n<<") = ";
gcd(m, n);
return 0;
}
void gcd(int m, int n)
{
int r, q, d;
while (n!=0)
{
r = m % n;
q = m / n;
r = m - n * q; // I was thinking on put it on the stack
but I dont know how
m = n;
n = r;
}
d = m;
cout<<d<<endl;
//then pop the stack as d=r-q*n
}
