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...

In this method the long atribute is a reference to a string which by the way is a ip adress of a machine. I cannot change the c api, so how can I in c#, get the pointer of such string and pass it to the function? I have already tried marshalling and all that stuff but nothing...

<string.h>是C语言中和字符串相关的头文件。C语言的内置数据类型中不包括字符串,只有字符数组char[],<string.h>中将字符数组的一些常用操作封装在其中,包含比如strlen、strcmp、strcpy、strcat之类的字符串处理函数。要注意它对应的是字符数组,本身并不是字符串数据类型。
Unless otherwise noted, passing a null argument to a constructor or method in this class will cause a NullPointerException to be thrown. A String represents a string in the UTF-16 format in which supplementary characters are represented by surrogate pairs (see the section Unicode Character Repre...
