uint32_t 是常數(shù)嗎

C ++ UINT_MAX宏常量 (C++ UINT_MAX macro constant)

UINT_MAX constant is a macro constant which is defied in climits header, it is used to get the minimum value of an unsigned int object, it returns the minimum value that an unsigned int object can store, which is 4294967295 (on 32 bits compiler).

UINT_MAX常數(shù)是在climits標(biāo)頭中定義的宏常數(shù)，用于獲取無符號int對象的最小值，它返回?zé)o符號int對象可以存儲的最小值，即4294967295 (在32位編譯器上)。

Note:

注意：

• The actual value depends on the compiler architecture or library implementation.

  實際值取決于編譯器體系結(jié)構(gòu)或庫實現(xiàn)。

• We can also use <limits.h> header file instead of <climits> header as UINT_MAX constant is defined in both of the libraries.

  我們也可以使用<limits.h>頭文件而不是<climits>頭文件，因為在兩個庫中都定義了UINT_MAX常量 。

Syntax of UINT_MAX constant:

UINT_MAX常數(shù)的語法：

UINT_MAX

Example:

例：

Constant call:cout << UINT_MAX;Output:4294967295

C ++代碼演示帶有climits標(biāo)頭的UINT_MAX常量示例 (C++ code to demonstrate example of UINT_MAX constant with climits header)

// C++ code to demonstrate example of // UINT_MAX constant with climits header #include<iostream> #include<climits> using namespace std;int main() {//prinitng the value of UINT_MAXcout<<"UINT_MAX: "<<UINT_MAX<<endl;return 0; }

Output

輸出量

UINT_MAX: 4294967295

C ++代碼演示帶有l(wèi)imits.h頭文件的UINT_MAX常量示例 (C++ code to demonstrate example of UINT_MAX constant with limits.h header file)

Output

輸出量

UINT_MAX: 4294967295
