can you explain this while

Question

#include <stdio.h>
int main ()
{
int A[10]= {64,56,42,55,58,46,44,64,42,46};
int B[10]= {72,96,86,72,92,96,84,72,68,82};
int N,m,n,s,X;

N = 1;
m = A[N]; n = B[N];
if (m<n)
{X = m; m=n; n=X;
}
while (n != 0)
{X = m/n;
s = m - X * n;
m = n;
n = s;
}
printf ("%i", m);
}

Answer 1

If you are asking for a while then I think it's easy, correct me if wrong.

While loop
Do u know about while?
It runs specific code block
ex: { printf("hello"); }
As long as x = 2
If x changes value it will stop.

Here while loop will work as Long as n is not equal to 0,
As long as n's value not equal to 0, x's value will be the quotient of the division between m and n

S's value will be subtraction X and multiplied by n
M will be equal to n
And n will be equal to s.
