int strcmp(const char *string1, const char *string2); 比较字符串string1和string2大小. 返回值< 0, 表示string1小于string2; 返回值为0, 表示string1等于string2; 返回值> 0, 表示string1大于string2. int stricmp(const char *string1, const char *string2); 比较字符串string1和string2大小,和strc...
1、substr函数格式 (俗称:字符截取函数) 格式1: substr(string string, int a, int b); 格式2:substr(string string, int a) ; 解析: 格式1: 1、string 需要截取的字符串 2、a 截取字符串的开始位置(注:当a等于0或1时,都是从第一位开始截取) ...

C-String, SubStr, and Strtok So, this might be the most confusing part of C++ for me thus far. Even having my friend show me a code for supposedly SubStr and Strtok has me dumbfounded (See his example code below) from what i understand it removes the spaces and any/all punctuation. ...
