Write "3" in C++ program that prints a LOGO consisting of 20 X 20 characters

Algorithm: Create a LOGO-like Program to Print the Number "3" in a 20x20 Grid

1. Start

2. Define a constant variable "size" as 20 to represent the size of the grid.

3. Declare a 2D character array "logo" with dimensions [size][size] to represent the grid.

4. Initialize the "logo" grid:
   - Loop through each row and column of the grid.
   - Set each element of the grid to a space character (' ').

5. Define the pattern for the number "3" in the "logo" grid:
   - Loop through each row and column of the grid.
   - Set the following elements to the specified characters to form the number "3":
     - Vertical line on the right: Set logo[i][size - 1] = '|'
     - Top horizontal line: Set logo[0][i] = '_'
     - Middle horizontal line: Set logo[size / 2][i] = '_'
     - Bottom horizontal line: Set logo[size - 1][i] = '_'

6. Print the "logo" grid:
   - Loop through each row and column of the grid.
   - Print each character in the grid.
   - Print a newline character ('\n') after each row.

7. End
