nested looping C++

Question

i want to asking this problem. this output is the expected output

*
*#
*#%
*#%*
*#%*#
*#%*#%

and this is my solution

#include <iostream>

using namespace std;


int main(){

  int a,b,n;

  cout << "Input the row";
  cin >> n;


  for (a = 1; a <= n; a++){
    for(b = 1; b <= a; b++){
        if (b == 1 || b == 1 + 3){
            cout << "*";
        }
        if (b ==2 || b == 2 + 3){
            cout << "#";
        }
        if (b ==3 || b == 3 + 3){
            cout << "%";
        }
    }
    cout << endl;
  }
}

this solution is only work if the n = 6. what should i do if i want this work in every row when user input the row to the n thank you in advance.

Here, I tried using the modulo "%" on your if's

#include <iostream>

using namespace std;


int main(){

  int a,b,n;

  cout << "Input the row";
  cin >> n;


  for (a = 1; a <= n; a++){
    for(b = 1; b <= a; b++){
        // After every first digits will cout #
        if (b % 3 == 2){
            cout << "#";
        }
        // The first after the third digit will cout *
        if (b % 3 == 1){
            cout << "*";
        }
        // The third digit after the second digit will cout % 
        if (b % 3 == 0){
            cout << "%";
        }
    }
    cout << endl;
  }
}
