c++ - Const char * 与 const wchar_t*(串联)

Question

哪种连接方式最好？

const char * s1= "\nInit() failed: ";
const char * s2 = "\n";
char buf[100];
strcpy(buf, s1);
strcat(buf, initError);
strcat(buf, s2);
wprintf(buf);

它给出了错误。正确的做法应该是什么？

谢谢。

我认为正确的做法是:

std::string msg = std::string("Init() Failed ") + initError + "\n";
std::cout<<msg;

或

std::cout<<"Init() Failed "<<initError<<"\n";
