Jan 11, 2025 · C/C++ provides macros INT_MAX and INT_MIN to represent the maximum and minimum values of the integer data type, facilitating easier variable assignments and overflow checks.

Aug 2, 2021 · The limits for integer types are listed in the following table. Preprocessor macros for these limits are also defined when you include the standard header file <climits>. Limits on Integer Constants

Mar 20, 2024 · INT_MAX 和 INT_MIN 是 C++ 的两个 预定义宏，代表了整型变量能够存储的 最大正整数和最小负整数，分别为 2147483647 和 -2147483648。 这两个宏在头文件 <climits> 中定义。 INT_MAX 表示一个 32 位符号整数所能够表示的最大值，也就是 2^31 − 1。 而 INT_MIN 则表示最小的负整数。 这个值是相对于二进制补码表示法的，也就是说，负数的范围比正数大 1。 …

Dec 6, 2009 · Is there any code to find the maximum value of integer (accordingly to the compiler) in C/C++ like Integer.MaxValue function in java?

Aug 3, 2022 · INT_MAX is a macro which represents the maximum integer value. Similarly, INT_MIN represents the minimum integer value. These macros are defined in the header file <limits.h> , so you must include it.

Dec 9, 2020 · The maximum value that can be stored in int is stored as a constant in <climits> header file whose value can be used as INT_MAX. A minimum integer value that can be stored in an int data type is typically -2, 147, 483, 648 , around -2 31 , but is compiler dependent.

Dec 16, 2022 · You can use either __INT_MAX__ or INT_MAX to get the maximum value of an int type, but it is generally recommended to use INT_MAX since it is defined in a standard library header file and is therefore more portable.

Feb 3, 2025 · The types of these constants, other than CHAR_BIT and MB_LEN_MAX, are required to match the results of the integral promotions as applied to objects of the types they describe: CHAR_MAX may have type int or unsigned int, but never char.

Jan 14, 2025 · In C++ programming, understanding the boundaries of integer data types is crucial for preventing overflow and ensuring reliable code. The climits library provides these essential limits, with...

This header defines constants with the limits of fundamental integral types for the specific system and compiler implementation used. The limits for fundamental floating-point types are defined in <cfloat> (<float.h>). The limits for width-specific integral types and other typedef types are defined in <cstdint> (<stdint.h>).
