please anyone tell about this code, i cant understand ( rekursif )

Question

#include <iostream>

void cetak(int n){
if(n == 0) return;

cetak(n-1);
std::cout << n << " ";
}

int main(){
cetak(10);
return 0;
}

Answer 1

cetak(10) -> 10==0? no, then << 1 cetak(10-1)-> 9==0? no, then << 2
cetak(9-1)-> 8==0? no, then << 3
cetak(8-1)-> 7==0? no, then << 4
cetak(7-1)-> 6==0? no, then << 5
cetak(6-1)-> 5==0? no, then << 6
cetak(5-1)-> 4==0? no, then << 7
cetak(4-1)-> 3==0? no, then << 8
cetak(3-1)-> 2==0? no, then << 9
cetak(2-1)-> 1==0? no, then << 10
cetak(1-1)-> 0==0? yes, return;
while not exit from the last recursive function, we will not go forward.
