Nettet9. apr. 2024 · 一、标准库中的string类. 1. C语言中的字符串. C语言中,字符串是以’\0’结尾的一些字符的集合,为了操作方便,C标准库中提供了一些str系列的库函数,但是这些库函数与字符串是分离开的,不太符合OOP的思想,而且底层空间需要用户自己管理,稍不留神 … Nettetint bitOr( int x, int y); Completing this function will require determining an alternative way to compute OR; your knowledge of Boolean logic from Discrete Mathematics will be critical to your success. The restrictions stated in the header comment for the function are mandatory; no credit will be allowed for solutions that
