While loop error

I don't understand why program doesn't work. It should print 3,6,9,12,15,18; #include <iostream> using namespace std; int main() { //change the code int num = 0; while(num<=20){ if (num%3=0) cout <<num; else num+=1; return 0; }

There are a few things, you can see in the update as follows: #include <iostream> using namespace std; int main() { //change the code int num = 0; while(num<=20){ if (num%3==0) cout <<num<<" "; // else num+=1; } return 0; }

So i have this: #include <iostream> using namespace std; int main() { //change the code int num = 0; while(num<=20){ cout<<num<<endl; num+=1; } return 0; } and I need to change the program to only print 3,6,9,12,15,18 instead of all from 1 to 20

#include <iostream> #include <string> using namespace std; int num=20; while (num >= 1){ num-=1; If((num%3)==0){ cout<<num; continue; } else{ continue; } } /*IMHO this should work*/
