﻿ C++ : Show a pattern like pyramid using the alphabet

# C++ Exercises: Display the pattern like pyramid using the alphabet

## C++ For Loop: Exercise-48 with Solution

Write a program in C++ to display the pyramid pattern using the alphabet.

Sample Solution:

C++ Code :

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

int main() // Main function where the execution of the program starts
{
int i, j; // Declare integer variables i and j
char alph = 'A'; // Declare and initialize a character variable alph with 'A'
int n, blk; // Declare integer variables n and blk
int ctr = 1; // Initialize an integer variable ctr with value 1

// Display message asking for input
cout << "\n\n Display the pattern like pyramid using the alphabet:\n";
cout << "---------------------------------------------------------\n";
cout << " Input the number of Letters (less than 26) in the Pyramid: ";
cin >> n; // Read input for the number of letters from the user

for (i = 1; i <= n; i++) // Loop for the number of rows
{
for (blk = 1; blk <= n - i; blk++) // Loop to print spaces before the characters
cout << "  "; // Print two spaces for formatting

for (j = 0; j <= (ctr / 2); j++) // Loop to print characters in ascending order
{
cout << alph++ << " "; // Print the character and increment the value of alph
}

alph = alph - 2; // Decrement alph by 2 to get the previous character
for (j = 0; j > (ctr / 2); j++) // Loop to print characters in descending order
{
cout << alph-- << " "; // Print the character and decrement the value of alph
}

ctr = ctr + 2; // Increment ctr by 2 for the next row
alph = 'A'; // Reset alph to 'A' for the next row
cout << endl; // Move to the next line after each row is printed
}
}
``````

Sample Output:

``` Display the pattern like pyramid using the alphabet:
---------------------------------------------------------
Input the number of Letters (less than 26) in the Pyramid: 5
A
A B A
A B C B A
A B C D C B A
A B C D E D C B A
```
