Question

I need to create a program that creates a random number in assembly and keep guessing until i get it between 1 -100.

So the first part of the program will generate a random number between 1 to 100. The next part will ask me in a loop to keep guessing until I get the correct number and asks me if I want to play again.. I just need that, nothing more, nothing less.

For example, the program randomly generates 51

"I am thinking of a number between 1-100"

Guess a number: 70

>too high, guess again

25

>too low, guess again

51

>correct! Would you like to play again?

n
