如何初始化unsigned char数组？
我真正想要实现的是一组动态字节模式，当我缓冲二进制文件时，我可以将其用作模式搜索器。 但我现在开始基本。 我有以下代码，我基于StackOverflow上的示例。
如何在C中初始化多维Char数组？
typedef unsigned char BYTE; int main() { BYTE *p[2][4] = { {0x44,0x58,0x54,0x31}, {0x44,0x58,0x54,0x00} }; return 0; } 我使用mingw32 for Windows编译它。
D:\> gcc example.c -o example.exe
我尝试编译时收到以下警告。
example.c: In function 'main': example.c:6:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:6:3: warning: (near initialization for 'p[0][0]') [enabled by default] example.c:6:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:6:3: warning: (near initialization for 'p[0][1]') [enabled by default] example.c:6:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:6:3: warning: (near initialization for 'p[0][2]') [enabled by default] example.c:6:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:6:3: warning: (near initialization for 'p[0][3]') [enabled by default] example.c:7:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:7:3: warning: (near initialization for 'p[1][0]') [enabled by default] example.c:7:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:7:3: warning: (near initialization for 'p[1][1]') [enabled by default] example.c:7:3: warning: initialization makes pointer from integer without a cast [enabled by default] example.c:7:3: warning: (near initialization for 'p[1][2]') [enabled by default]
我不明白这个警告的性质。 我该如何解决它？ 谢谢。
从BYTE *p[2][4]删除* ：
BYTE p[2][4] = { {0x44,0x58,0x54,0x31}, {0x44,0x58,0x54,0x00} };
你想要一个char的多维数组： BYTE p[2][4]而不是pointer-to-char的多维数组。
