char： 通常占用1个字节。在C语言中，char 用于表示字符，而标准规定一个字符占用1个字节。int： int 的大小在不同的系统上可以变化，但通常是4个字节或者2个字节。在大多数现代计算机上，int 被设计为能够表示计算机的自然字大小，即32位或64位。在一些嵌入式系统或特殊体系结构中，int 也可能是2个字节。如果...
C语言中的char数据类型是一种整数类型(integer type),它的大小被定义为1个Byte。亦即 sizeof (char) ≡ 1 若需要知道某个具体编译器的Byte究竟是多少位,可以查看编译器提供的limits.h。其中定义的符号常量CHAR_BIT就是char类型的位数,也就是Byte的位数。 补充: C标准的矛盾? "addressable unit of data large ...
char * const:顶层const,const修饰指针本身,说明指针本身是常量,表示定义的指针不可以再指向其他的地址; 2.2 C语言中处理字符的函数 求字符串的长度: strlen:可以用于计算字符数组中,字符的长度;也可用于计算字符指针所指向的字符串长度; sizeof:用于求字符数组的长度; char *str1 = "hello!";//sizeof(str1)...
The C++ standard does not specify the size of integral types in bytes, but it specifies minimum ranges they must be able to hold. You can infer minimum size in bits from the required range and the value of CHAR_BIT macro, that defines the number of bits in a byte (in all but the m...

Hi, I'm trying to pass some bytes from a C function into a Python function, but it's always terminated by the 0x00 byte in it. I know that the 0x00 byte is supposed to be the terminator of strings in C. But in pure C, it's not difficult ...

Fixed-size string data. n defines the string size in bytes and must be a value from 1 through 8,000. For single-byte encoding character sets such as Latin, the storage size is n bytes and the number of characters that can be stored is also n. For multibyte encoding character sets, th...
