C++ Programming: Generating Random Puzzles

How does the program in C++ randomly select a puzzle from a specific category?

Can you explain the process of selecting a puzzle and hiding its letters using '#'?

The problem statement provided describes a C++ program where the player selects a category, and the program then randomly selects a puzzle from the array of Puzzle structs within that category. The Puzzle struct contains the category and the puzzle itself.

In order to select a puzzle from a particular category, the program first generates a random integer ranging from 0 to the total number of puzzles in that category minus one. This random integer serves as the index to select a puzzle from the array of puzzles in that category.

If the selected puzzle is not from the desired category, the program repeats the process of generating a random integer and selecting a puzzle until one from the desired category is found.

Once a puzzle from the desired category is selected, the program uses the character '#' to hide the letters of the puzzle. However, any spaces or dashes ('-') in the puzzle are revealed to the player.

For example, if the player chooses the 'Household Items' category and there are two puzzles in that category: 'FULL-LENGTH WALL MIRROR' and 'PORCELAIN VASE', the program will randomly select one of these puzzles from the array.

After selecting a puzzle, the program displays it with the letters hidden using '#'. For instance, if the puzzle is "FULL-LENGTH WALL MIRROR", it will be shown as "####-###### #### ######", indicating that spaces and dashes have been revealed while the letters are hidden.
