CString与const char*转换

Format函数也是很不错的.

1. string转const char*   string s = "abc";   const char* c_s = s.c_str();2. const char*转string   直接赋值即可   const char* c_s = "abc";   string s(c_s);3. string转char*   string s = "abc";   char* c;   const int len = s.length();   c = new char[len+1];   strcpy(c,s.c_str());4. char*转string   char* c = "abc";   string s(c);5. const char*转char*   const char* cpc = "abc";   char* pc = new char[100];//足够长   strcpy(pc,cpc);6. char*转const char*   直接赋值即可   char* pc = "abc";   const char* cpc = pc;
