C++ Program:

- To print full odd reverse triangle pattern using *

Example:

User Input: 3

Output:

*   *   *
  *   *
    *
#include <iostream>
using namespace std;

int main() {
  int rows;
  cout <<"Enter number of rows: ";
  cin >> rows;
  for(int i=1; i<=rows; i++) {
    for(int j=1; j<=(2*rows-i); j++) {
      if(j>=i && (j+i)%2==0)cout<<"* ";
      else cout<<"  ";
    }
    cout<<endl;
  }
  return 0;
}

Output:

Enter number of rows: 4

pattern

Main Logic :

for(int i=1; i<=rows; i++) {
  for(int j=1; j<=(2*rows-i); j++) {
    if(j>=i && (j+i)%2==0)cout<<"* ";
    else cout<<"  ";
  }
  cout<<endl;
}

You can print any thing in this pattern, just replace your value with *
