如何在C / C ++中定义字节数组？ [英] How to define byte array in C/C++?

问题描述

我必须在C / C ++中定义字节数组

我搜索网并找到各种例子，所以很困惑哪一个是正确的： -

其中一个是哪一个是正确的吗？

  unsigned   char  bytes [] = 0x43,0x4d，0x30,0x30,0x0f，0X0D}; 
 
  const   char  data3 [] = {0x43,0x4d，0x30,0x30 ，0xf0,0x0D}; 
 
  char 数据[ 4 ] =   CM00; 

解决方案

所有它们是有效的（当然，在第一个中，缺少开放的大括号）。

参见基本类型 [ ^ ]和下标 [ ^ ]。

字节测试[5 ] = {0xb4,0xaf，0x98,0x1a，0xB5执行};

i have to define byte array in C/C++
I searched net and found various examples,so confused which one is correct:-
Out of these which one is correct?

unsigned char bytes[]=0x43,0x4d,0x30,0x30,0x0f,0x0D};

const char data3[]={0x43,0x4d,0x30,0x30,0xf0,0x0D};

char data[4]="CM00";

解决方案

All of them are valid (of course, in the first one, the open curly brace is missing).

See fundamental types[^] and subscripts[^].

byte test[5]={0xb4,0xaf,0x98,0x1a,0xb5};
