﻿ C++ : Pattern like a pyramid with numbers increased by 1

# C++ Exercises: Display the pattern like a pyramid with numbers increased by 1

## C++ For Loop: Exercise-39 with Solution

Write a C++ program to make such a pattern like a pyramid with numbers 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, spc, rows, k, t = 1; // Declare integer variables i, j, spc, rows, k, and t with t initialized to 1

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

spc = rows + 4 - 1; // Calculate the number of spaces for formatting

// Loop to print the pyramid pattern with numbers increased by 1
for (i = 1; i <= rows; i++) // Loop for the number of rows
{
for (k = spc; k >= 1; k--) // Loop to print spaces before the numbers
{
cout << " "; // Print a space
}

for (j = 1; j <= i; j++) // Loop to print numbers in each row
{
cout << t++ << " "; // Print the value of 't' (increased by 1) and increment 't' afterwards
}

cout << endl; // Move to the next line after each row is printed
spc--; // Decrement the number of spaces for the next row
}
}
``````

Sample Output:

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