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...

Thus, the preprocessor searched inside string literals and character constants for characters that looked like macro parameters. ISO C recognized the importance of this feature, but could not condone operations on parts of tokens. In ISO C, all invocations of the above macro produce the string ...
