}

the instruction to this code is to make the user write numbers from 1-100 and the application should categorize the numbers in the following way

100 - A
90-99 - B
80-89 - C
70-79 - D
60-69 - E
other - F


the problem is with the other. it should go from 59 to 0.

however, the application categorizes any number as "others"

how can i cause the application to accept numbers from 0-100 and not accept numbers higher than 100?

Yeah...I would say your in the wrong section

I want to add that i cant use if or while function

You should be posting in the Java section not the C section.

i thought they are both the same.

java and c

Yep, wrong forum, yet I'll fix it.
String input; is wrong, change to:

String input = new String();

i thought they are both the same.

Do Apple's taste like Orange?

problem is solved.
