本文介绍了C ++数据类型与C#数据类型的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

作为一个专业的C#程序员学习C ++,我想保持数据类型与C#相同。我写了一个头文件,应该帮助这个。我想知道的是如果是正确的。

  // boolean 
//#DEFINE bool char
//#DEFINE true 0x01
//#DEFINE false 0x00

// 8位整数
#DEFINE字节unsigned char
#DEFINE UInt8 unsigned char
#DEFINE字节无符号字符
#DEFINE sbyte char
#DEFINE Int8 char
#DEFINE SByte char

// 16位整数
#DEFINE ushort unsigned short int
#DEFINE UInt16 unsigned short int
#DEFINE short short int
#DEFINE Int16 short int

// 32位整数
#DEFINE uint unsigned int
#DEFINE UInt32 unsigned int
//#DEFINE int int
#DEFINE Int32 int

// 64位整数
#DEFINE long long long
#DEFINE Int64 long long
#DEFINE ulong unsigned long long
#DEFINE UInt64 unsigned long long

// 32位浮点
//#DEFINE float float
#DEFINE单浮点

// 64位浮点
//#DEFINE double double
# DEFINE Double double


解决方案

除了可怕的风格,

  #define long long long 





反转宏定义的顺序无法完全解决问题。





也会出现类似问题。

  #define short short int

As a professional C# programmer learning C++, I would like to keep data types the same as in C#. I wrote a header file that should help with this. What I want to know is if it is correct.

// boolean
//#DEFINE bool char
//#DEFINE true 0x01
//#DEFINE false 0x00

// 8-bit integers
#DEFINE byte unsigned char
#DEFINE UInt8 unsigned char
#DEFINE Byte unsigned char
#DEFINE sbyte char
#DEFINE Int8 char
#DEFINE SByte char

// 16-bit integers
#DEFINE ushort unsigned short int
#DEFINE UInt16 unsigned short int
#DEFINE short short int
#DEFINE Int16 short int

// 32-bit integers
#DEFINE uint unsigned int
#DEFINE UInt32 unsigned int
//#DEFINE int int
#DEFINE Int32 int

// 64-bit integers
#DEFINE long long long
#DEFINE Int64 long long
#DEFINE ulong unsigned long long
#DEFINE UInt64 unsigned long long

// 32-bit floating point
//#DEFINE float float
#DEFINE Single float

// 64-bit floating point
//#DEFINE double double
#DEFINE Double double
解决方案

Aside from the horrendous style, these macros don't even work the way you expect.

#define long long long

is prone to all sorts of problems.

Reversing the order of the macro definitions doesn't fix the problem completely either.

Similar problems occur with

#define short short int
