Thread: guessing a number

There is a program in which i am facing difficulties.
The question is that the user thinks of a number and the
computer guesses it. We have to guess the numbers from
1 to 100. If we guess 93 in our mind then we'll have to do
this step :

(50+100)/2=75

if the number we guessed is greater than 75 then.

( 100 + 75)/2= 87

if the number is greater than 87 then,

(100+87)/2=98

if the number is less than 98 then,

(98+87)/2=92

if the number is greater than 92 then,

(98+92)/2=95

if the number we guessed is less than 95 then,

(95+92)/2=93

93 was the number we guessed.


We have to take only '>' , '<' or '=' as inputs.
hope u understand.

try searching for binary search. but you will need:

high variable
low variable
mid variable

do this in a loop. use if statements to check if the number is equal to, less than, or greater than and adjust the variables accordingly.
