Question

I have a task to complete the task is to print Star(*)Triangle on right side in C++ using For Loop/if statement i write program but it give output like this.

But i want to output like this.

        **
         *

So, please help or tell me by making what changes in my code i can print triangle like this.

//Program to print triangle on Right Side.

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{int number, i,j;
 cout << "Enter the Number :";
 cin >> number;

 for (i=number; i>=1; i--)
 {
 for (j=1; j<=i; j++)
 {
     if (j==1 || j==i || i==number)
     {
        cout << "*";
     }
     else
     {
         cout << " ";
     }
 }
    cout << endl;
 }
 getch();
 return 0;
 }

I think that may be some changing in if statement can generate triangle that i want but i am unable to do give me some advice so i can solve this.

Solution

#include<iostream>
using namespace std;

int main()
{
    int i, j, k,number;
    cin>>number;
    for(i=number;i>=1;i--)
    {
        for(j=number;j>i;j--)
        {
            cout << " ";
        }
        for(k=1;k<=i;k++)
        {
            cout << "*";            
        }
        cout <<endl;
