Character Pattern: Repeating Letters

Introduction:

In this section, we will explore the repeating letters pattern, which demonstrates how to use loops & character manipulation in programming.

Visual Representation:

Letter pattern:

AAAAA
BBBBB
CCCCC
DDDDD
EEEEEE

Pattern Explanation:

The pattern of repeating letters consists of n rows, each row containing an increasing letter (starting from 'A') repeated n times.

Code Explanation: 

Here's the code to generate a repeating letter pattern in C:

include<stdio.h> 
int main()
{
int row_size;//Declaration of row size
printf("Enter Number of Rows:");
scanf("%d",&row_size);//User Input of row_size
int row, col;//Declaration for rows & columns
for(row=65;row<(65+row_size);row++)//ASCII value of 'A'=65
{
       for(col=0;col<row_size;col++)       {
           printf("%c", row);
       }
       printf("\n");
}
return 0;
}

Breakdown of Code:

• Variable Declaration: We declare row_size to hold the number of rows, row and col for iteration.
• Input Prompt: The user is prompted to enter the number of rows.
• Outer Loop: The outer loop iterates through the rows, starting from ASCII value of 'A'(65).
• Inner Loop: The inner loop prints the current character row , repeated n times.
• New Line: After printing each row, a new line is printed.

Common Mistakes:

->Incorrect ASCII Handling: Ensure correct handling of ASCII values to print the desired characters.

->Loop Bounds: Verify that the loop bounds are set correctly to avoid out-of-bounds errors.

FAQ:

Q1. Why use ASCII values for characters?

Ans: Using ASCII values allows for easier manipulation of character sequences and ensures compatibility.

Q2. Can I use lowercase letters instead?

Ans: Yes! You can adjust the starting ASCII value to 97 for 'a' to print lowercase letters.

Q2. Can I use direct characters instead of ASCII values?

Ans: Yes! You can use direct characters; the compiler will convert them into equivalent ASCII values. However, it is suggested that you use ASCII values.
