Question

Use C++ to program a system that lets people guess a random number between 506 and 783 twice. The guesser must know if the number is correct. If not, then they must know how much higher or lower their guess is from the randomly selected number.

Expert Solution

Step 1: Write an Algorithm

Include necessary C++ libraries for input and output, as well as for generating random numbers.
Seed the random number generator with the current time.
Generate a random number between 506 and 783 using rand() % 278 + 506. Store it in the variable randomNumber.
Prompt the user to make their first guess and store it in the variable guess1.
Compare guess1 with randomNumber.
1. If guess1 is equal to randomNumber, display "Congratulations! Your guess is correct."
2. If guess1 is less than randomNumber, display "Your guess is lower than the random number."
3. If guess1 is greater than randomNumber, display "Your guess is higher than the random number."
Prompt the user to make their second guess and store it in the variable guess2.
Compare guess2 with randomNumber.
1. If guess2 is equal to randomNumber, display "Congratulations! Your guess is correct."
2. If guess2 is less than randomNumber, display "Your guess is lower than the random number."
3. If guess2 is greater than randomNumber, display "Your guess is higher than the random number."
Display the actual random number to the user.
Terminate the program.
