WebFeb 23, 2024 · INT_MAX is a macro that specifies that an integer variable cannot store any value beyond this limit. INT_MIN specifies that an integer variable cannot store any value below this limit. Values of INT_MAX and INT_MIN may vary from compiler to compiler. Following are typical values in a compiler where integers are stored using 32 bits. WebFeb 26, 2009 · 12. Nope, there is no standard for type sizes. Standard only requires that: sizeof (short int) <= sizeof (int) <= sizeof (long int) The best thing you can do if you want variables of a fixed sizes is to use macros like this: #ifdef SYSTEM_X #define WORD int #else #define WORD long int #endif.
