Secret Number
This program is a secret number game. The object is to guess the
randomly chosen number between 1 and an upper limit you inpllt
For each guess. you enter two numbers: a low and a high guess.
The computer will tell you if the secret number is less than. greater
than. or between the two numbers you enter. When yOll think yOll
know the number. enter the same value for both the low and high
guesses.
The RANDOMiZE statement ensures a different sequence of
numbers each time the program is run, MSGl$ and MSG2$ are
repeatedly used in PRINT statements. The CALL CLEAR
statement clears the screen
The INPUT statement stops the program and waits for you to enter
a limit. Then the secret number is generated. and the screen is
cleared. N is used to
keep track of the number of guesses you
make.
This INPUT statement accepts your low and high guesses. If you
enter the same number for both guesses and you guess the secret
number. the program transfers to line 300. If the senet number is
less than your low number, the program transfers to line 260. If the
secret number is greater than your high number, the program
transfers to line 280. If the secret llumbcI i~ uel ween yuur two
numbers or equal to one of your numbers. the program continues.
These statements print a message to tell you where the secret
number is in relation to your guesses. Then the program transfers
to line 180 to allow you to guess again. If you guessed the secret
numher, the ('flmpllter tells you how many guesses you took.
