In 1971 I began to extend the B language by adding a character type and also rewrote its compiler to generate PDP-11 machine instructions instead of threaded code. Thus the transition from B to C was contemporaneous with the creation of a compiler capable of producing programs fast and small ...

1.char类型数组与null字符 C语言没有用于专门存储字符串的变量类型,字符串都被存储在char类型的数组中。数组由连续的存储单元组成,字符串中的字符被存储在相邻的存储单元中,每个单元存储一个字符。 2.字符串与字符 字符串常量"x"与字符常量'x'不同,前者是派生类型(char数组),后者是基本类型(char)。字符串常量"...

char_16_t and char32_t You can no longer use char16_t or char32_t as aliases in a typedef, because these types are now treated as built-in. It was common for users and library authors to define char16_t and char32_t as aliases of uint16_t and uint32_t, respectively. C++ Cop...
