This code splits a comma-separated string into individual tokens.strtok_smaintains its state in thecontextpointer. The first call uses the string to tokenize, while subsequent calls use NULL. Each call returns a

应该这样用：char c[20];string s="1234";strcpy(c,s.c_str());这样才不会出错，c_str()返回的是一个临时指针，不能对其进行操作。语法: const char *c_str();c_str()函数返回一个指向正规C字符串的指针, 内容与本string串相同.，这是为了与c语言兼容，在c语言中没有string类型，故必须...
I have a string,"004-034556", that I want to split into two strings: 我有一个字符串,“004-034556”,我想把它分成两个字符串: string1=004 string2=034556 1. 2. That means the first string will contain the characters before'-', and the second string will contain the characters after'-...
