Write a program that only uses getchar() for input, and can input a double number. You can use printf() to print the integer and confirm it was read in correctly. Assume the number is positive.
ı just started c.I have no idea how to solve this problem.Is there any help with this question?
It sounds like your instructions are contradictory: you are told "can input a double number" and also "print the integer and confirm it was read in correctly". So, is the input in the format of a double or an integer? Check with your instructor.
If your instructor says double, then also check what exactly is the format as double allows for scientific notation. I would guess it would only be a simple sequence of digits, decimal point, then more digits.

could you write as a code?
Yes, start by writing a getchar() loop which prints a message depending on whether the input character is '0' to '9' (good) or anything else (bad).

Not until you post some effort of your own.

If you want to cheat on your homework assignment, why don't you just google "c language getchar()"?
Involving us just seems like not learning with more steps.
