C++ Exercises: Display the pattern like right angle triangle with number

C++ For Loop: Exercise-36 with Solution

Write a program in C++ to display the pattern like right angle triangle with number.

Pictorial Presentation:

Sample Solution:-

C++ Code :

#include <iostream>
using namespace std;

int main()
{
   int i,j,rows;
    cout << "\n\n Display the pattern using number starting from 1:\n";
    cout << "------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows;
   for(i=1;i<=rows;i++)
   {
	for(j=1;j<=i;j++)
	   cout<<j;
	cout<<endl;
   }	
}

Sample Output:

 Display the pattern using number starting from 1:                     
------------------------------------------------------                 
 Input number of rows: 5                                               
1                                                                      
12                                                                     
123                                                                    
1234
