Print the pattern by using one loop | Set 2 (Using Continue Statement)

Given a number n, print triangular pattern. We are allowed to use only one loop.
Example:
Input: 7 Output: * * * * * * * * * * * * * * * * * * * * * * * * * * * *
We use single for-loop and in the loop we maintain two variables for line count and current star count. If current star count is less than current line count, we print a star and continue. Else we print a new line and increment line count.
// C++ program to print a pattern using single
// loop and continue statement
#include<bits/stdc++.h>
using namespace std;
// printPattern function to print pattern
void printPattern(int n)
{
// Variable initialization
int line_no = 1; // Line count
// Loop to print desired pattern
int curr_star = 0;
for (int line_no = 1; line_no <= n; )
{
// If current star count is less than
// current line number
if (curr_star < line_no)
{
cout << "* ";
curr_star++;
continue;
}
// Else time to print a new line
if (curr_star == line_no)
{
cout << "\n";
line_no++;
curr_star = 0;
}
}
}

Output:
* * * * * * * * * * * * * * * * * * * * * * * * * * * *
Time Complexity: O(n2)
Auxiliary Space: O(1)
