在C语言中,可以通过使用for循环来代替while循环来实现strstr函数。下面是一个示例代码: #include <stdio.h> #include <string.h> char* my_strstr(const char* haystack, const char* needle) { int len1 = strlen(haystack); int len2 = strlen(needle); for (int i = 0; i <= len1 - len2; i...

Immutability means that an instance, once created, will not change—or at least won't change during a fixed and well known period of time. A CLR string, for example, is immutable and therefore doesn't require a lock around accesses to its individual characters. If state isn't in motion,...
