Write a program that does the following.The program asks the user to enter a positive integer n.  The program prints a triangle with n rows using the number r to make the characters on row number r. For example, if the user enters 4 for n the output is as follows:
1
22
333
4444

 Code:- 

/*program to make triangle with n rows using the number r to make the

characters on row number r. */

#include<iostream>

using namespace std;

int main()

{

       int n,r,a,b=1;

       cout<<"Enter positive Integer= ";

       for(n=0;n<a;n++)

       {

              for(r=0;r<=n;r++)
