— Hi
— What statement can i use to make a program that tell the number of digits of entered integer ? Help me guys
— It is not one statement, it is a routine of several statements.
— U can use while loop and division on 10.
— Or u can use simple strlen(str), but u can't make mistakes when entering numbers and should typing only digit chars.
— The simplest way to do this is to enter a number (integer for example) , then convert integer to a string and count its characters which are digits by definition.
If you wanna train yourself you can do binary-to-decimal transformation yourself.
