C++ Program:

- To print half opposite reverse triangle pattern using *

Example:

User Input: 4

Output:

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

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

Output:

  Enter number of rows : 4
        *
      * *
    * * *
  * * * *
Program
pattern

Main logic :

for(int i=rows; i>=1; i--) {  //rows : number of rows to print
  for(int j=1; j<=rows; j++) {
    if(j<i)cout<<"  ";
    else cout<<"* ";
  }
  cout<<endl;
}

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