But in C programming language, a "bool" is defined in stdbool.h header file. Thus, to use a bool type in our program, we must include stdbool.h header files. As a standard feature, a bool variable can store either true (1) or false (0) value....
Is sizeof(bool) defined in the C++ language standard? 我在标准文档中找不到答案。 C ++语言标准是否要求sizeof(bool)始终为1(1字节),还是此大小由实现定义? sizeof(bool)是实现定义的,该标准特别强调了这一事实。 §5.3.3/ 1,摘要: sizeof(char),sizeof(signed char)andsizeof(unsigned char)are 1...
