﻿ C : Display the pattern like pyramid using the alphabet

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

## C For Loop: Exercise-40 with Solution

Write a C program to display the pyramid pattern using the alphabet.
The pattern is as follows :

```     A
A B A
A B C B A
A B C D C B A
```

Visual Presentation: Sample Solution:

C Code:

``````#include <stdio.h> // Include the standard input/output header file.

int main()
{
int i, j; // Declare variables for iteration.
char alph = 'A'; // Initialize a character variable to 'A'.
int n, blk; // Declare variables for user input and block counter.
int ctr = 1; // Initialize a counter.

printf("Input the number of Letters (less than 26) in the Pyramid : ");
scanf("%d", &n); // Prompt user for input and store it in variable 'n'.

for (i = 1; i <= n; i++) // Outer loop for rows.
{
for(blk = 1; blk <= n - i; blk++) // Loop to print spaces before letters.
printf("  ");

for (j = 0; j <= (ctr / 2); j++) // Loop to print letters in ascending order.
{
printf("%c ", alph++);
}

alph = alph - 2; // Decrement the character after printing half.

for (j = 0; j < (ctr / 2); j++) // Loop to print letters in descending order.
{
printf("%c ", alph--);
}

ctr = ctr + 2; // Increment the counter for the next row.
alph = 'A'; // Reset the character to 'A' for the next row.

printf("\n"); // Move to the next line after printing a row.
}
return 0;  // Indicate that the program has executed successfully.
}
```
```

Sample Output:

```Input the number of Letters (less than 26) in the Pyramid : 6
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
A B C D E F E D C B A
```
