2. resize(size_t n) 与 resize(size_t n, char c) 都是将字符串中有效字符个数改变到 n 个,不 同的是当字符个数增多时: resize(n) 用 0 来填充多出的元素空间, resize(size_t n, char c) 用字符 c 来填充多出的元素空间。注意: resize 在改变元素个数时,如果是将元素个数 增多,可能会改变...
Learn about the C++ string empty() function, which checks if a string is empty and returns a boolean value. Explore its usage with examples.
String function are the functions that are used to perform operations on a string. C++ uses <string.h> library to provides various string functions like strcat, strlen, strcmp, strcpy, swap, and many more where strcat is used to concatenate string, strlen will calculate the length of the str...

根据定义,任何字符串(包括 String.Empty)都会比较大于 null 引用,而两个空引用相互比较相等。 可以通过 options 参数进一步指定比较,该参数由 System.Globalization.CompareOptions 枚举的一个或多个成员组成。 但是,由于此方法的目的是执行区分区域性的字符串比较,因此 CompareOptions.Ordinal 和CompareOptions....
