Question

This is my coded "multipath adventure" that I created. Now I have to modify it to include loops but I am really struggling to do so. Below are the instructions and my current code that needs to be modified. Thank you in advance!

• You must have at least 1 for loop in your code
  • The for loop must actually be used as a loop, and it must have real effect in your program (it is theoretically possible to use the for loop syntax without actually using it as a loop or creating any real effect, but if you do this you will lose points)
• You must have at least 1 while loop in your code
  • The note on for loops above applies equally to this deduction regarding while loops
• You must have at least 1 instance of rand() in your code
  • Your use of rand() must have real effect in your program (it is possible to use rand() to generate a random number without actually using the random number, but if you do this you will lose points
• The above are REQUIREMENTS and below are just some SUGGESTIONS
  • Use a while loop to enable the player to play your game multiple times
  • Create an input function that utilizes a loop to prompt for and validate user input
    • Takes a prompt (string) as the argument
    • Returns the valid input (string)
  • For the requirement to use at least 1 for loop:
    • Consider using for loop(s) to draw box or stars around prompt in your input function (see above)
  • For the requirement to use at least 1 instance of rand():
    • Consider including a randomized process in your game, such as rolling a die, and using rand() to simulate the process
    • Consider including a point where the game randomly selects between multiple possible descriptions. For example, you could have the game randomly decide whether to describe the weather as "sunny" or "rainy".

#include<iostream>

choice1=arr[rand() % MAX]; // the function in RHS generates a random character either 'a' or 'b' and gets stored in the LHS variable.

Here I am attaching a screenshot of result for your reference.

All the choices were chosen randomly. You just need to make a choice after each iteration i.e whether you want to play again or not.

changes made to your code:

-> use of return(0) statement in every conditional block terminated the program there itself.Hence, while loop failed to work.

-> use of rand() function to make random choices.

-> use of goto statements according to requirement.

This code makes the game completely automatic. If you want to make a specific part as automatic then make necessary changes. If you need any help, Please make me know in the comment box.

Thank you.
