Why no output?
#include <iostream> using namespace std; int main() { #define root = 40; for(int x = root, k = 0; x > 0, k > 0; x/=10, k++) { cout << k << endl; } return 0; }

using namespace std;
int main()
{
int k;
for(int x = root;k = 0,x > 0, k > 0, x/=10, k++)

k = 0 isn't condition

The body of your for loop will be executed as long as “x > 0” and “k > 0” are true.
But initially k = 0, so the condition “k > 0” is false and the loop is exited.
