LIMITS.H

This header file provides constants that define the limits of fundamental data types. These constants help ensure that programs handle integer values safely within the boundaries supported by the system. For example, it defines the maximum and minimum values for types like int, char, and long, with constants such as INT_MAX, INT_MIN, CHAR_BIT, and LONG_MAX. These constants are crucial for ensuring that operations on numbers, like arithmetic, avoid overflow and underflow errors. Additionally, the file includes constants for size-specific types like SHRT_MAX for short integers and LLONG_MAX for long long integers. By including <limits.h>, developers can write more portable and robust code, as the constants adapt to the underlying hardware and system architecture.
