﻿ C++ : Right angle triangle pattern with number increase by 1

# C++ Exercises: Display the pattern like right angle triangle with number increased by 1

## C++ For Loop: Exercise-38 with Solution

Write a C++ program to make such a pattern like a right angle triangle with the number increased by 1.

Visual Presentation:

Sample Solution:

C++ Code :

``````#include <iostream> // Include the input/output stream library
#include <string>   // Include the string handling library
using namespace std; // Using standard namespace

int main() // Main function where the execution of the program starts
{
int i, j, rows, k = 1; // Declare integer variables i, j, rows, and k with k initialized to 1

// Display message asking for input
cout << "\n\n Display such a pattern like right angle triangle with number increased by 1:\n";
cout << "---------------------------------------------------------------------------------\n";
cout << " Input number of rows: ";
cin >> rows; // Read input for the number of rows from the user

// Loop to print the pattern with numbers increased by 1 in a right-angle triangle shape
for (i = 1; i <= rows; i++) // Loop for the number of rows
{
for (j = 1; j <= i; j++) // Nested loop for printing numbers in each row
{
cout << k++ << " "; // Print the value of 'k' (increased by 1) and increment 'k' afterwards
}
cout << endl; // Move to the next line after each row is printed
}
}
``````

Sample Output:

``` Display such a pattern like right angle triangle with number increased by 1:
---------------------------------------------------------------------------------
Input number of rows: 4
1
2 3
4 5 6
7 8 9 10
```
