Program Overview

This Python program uses nested loops to draw the uppercase letter 'C' using the '*' character.
The number of rows is taken as input and determines the height of the letter.
This exercise helps practice loop structures and conditional logic for rendering text-based shapes.

Python Code:

def draw_letter_c(rows):
    cols = rows  # Width of the letter C equals its height in this example
    for i in range(rows):
        for j in range(cols):
            if i == 0 or i == rows - 1:
                print("*", end="")
            elif j == 0:
                print("*", end="")
            else:
                print(" ", end="")
        print()

# Run the program
rows = int(input("Enter number of rows: "))
draw_letter_c(rows)

Sample Output (input: 6):

******
*     
*     
*     
*     
******

Step-by-Step Explanation:

- The outer loop iterates over rows, and the inner loop over columns
- The first and last rows are filled entirely with asterisks
- In other rows, only the first column contains an asterisk, creating a hollow shape
- This structure visually resembles the letter 'C'
