Is there anything similar to Java's Integer.MIN_VALUE in C, which gives the smallest possible value of a signed integer, or do I just have to hard code the value myself?

  • Do not hard-code the value yourself; you will get the value wrong for some platforms that your code is moved to (because an `int` could have 16 bits, or 32 bits — by far the most common size — or 64 bits, or indeed other sizes). But it is good that you asked before heading in the wrong direction. – Jonathan Leffler Aug 22 '15 at 17:46

You can use limits.h http://en.cppreference.com/w/c/types/limits

I think this is what you're looking for: INT_MIN = minimum value for an int

You will find INT_MIN and INT_MAX in <limits.h> (for plain int). Indeed, the header defines the limits for all the integer types: signed char, short, plain int, long and long long, with the prefixes SCHAR_, SHORT_, INT_, LONG_ and LLONG_. All these are required to exist per ISO C99 and C11 (and, except for long long, in C89).

In header limits.h you will get minimum and maximum value of data types.

For integer you can use -

  INT_MAX            //max value for signed integer

  INT_MIN           //min value for signed integer
