44. Program that inputs the height of a triangle and displays it using loop.

Chapter 6: 

Looping Structures

Programming Exercise

Problem # 44:

Write a program that inputs the height of a triangle and displays it using loop. For example, if the user enters height as 5, the program should print the following:
    &&&&&&&&&
       &&&&&&&
          &&&&&
             &&&
                &

Solution:

#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
    int i, j, n, k, m=1, l;
    cout<<"Enter the height of triangle:";
    cin>>n;
    for(j=1;j<=n;j++)
    {
        m=m+2;
    }  
    for(i=1;i<=n;i++)
    {
      
        for(k=i;k>1;k--)
        {
        cout<<" ";  
        }
      
        for(l=i;l<(m-i);l++)
        {
        cout<<"&";  
        }
        k--;
        cout<<"\n";      
    }
  
    getch();
}
