Number Guessing Logic

Goals

• Understand how a random target is generated and kept hidden
• Practice a while-loop that repeats until a condition is met
• Use conditional branches (higher / lower / equal) to guide the player
• Translate a real game rule into structured pseudocode

Prerequisites

• Variables and assignment
• if/else conditional statements
• while loops (or general loop concept)

Steps

2. 1

   Pick a secret number

   Declare a variable target and assign it a random integer between 1 and 100. In pseudocode you can write target ← random(1, 100). The value must be hidden from the player.

   CodeCopy

   target ← random(1, 100)
   print("I picked a number between 1 and 100.")

   Expected result

   The program announces it has a secret number; the player does not see the value.

4. 2

   Read the first guess

   Prompt the player for a guess and store it in a variable guess. Reading input is the only way the loop can make progress.

   CodeCopy

   print("Enter your guess: ")
   guess ← read_input()

   Expected result

   The program waits for the player to type a number.

6. 3

   Loop until correct

   Wrap the comparison in a while guess ≠ target loop. Inside the loop, print "Higher!", "Lower!", or break when equal. After each hint, read a new guess so the loop can terminate.

   CodeCopy

   while guess ≠ target:
       if guess < target:
           print("Higher!")
       else:
           print("Lower!")
       guess ← read_input()
   print("You got it!")

   Expected result

   Each wrong guess prints a hint and asks again; a correct guess exits the loop and prints a win message.

8. 4

   Count the attempts

   Add an attempts counter that starts at 0 and increments each time the player guesses. Print it at the end so the player sees their score.

   CodeCopy

   attempts ← 0
   while guess ≠ target:
       attempts ← attempts + 1
       ...
   print("Solved in", attempts, "tries.")

   Expected result

   After winning, the program shows how many guesses the player used.
