convert unsigned char* to std::string

Question

I am little poor in typecasting. I have a string in xmlChar* (which is unsigned char*), I want to convert this unsigned char to a std::string type.

xmlChar* name = "Some data";

I tried my best to typecast, but I couldn't find a way to convert it.

Answer 1

std::string sName(reinterpret_cast<char*>(name));

reinterpret_cast<char*>(name) casts from unsigned char* to char* in an unsafe way but that's the one which should be used here. Then you call the ordinary constructor of std::string .

You could also do it C-style (not recommended):

std::string sName((char*) name);

Answer 2

I think the accepted solution is a little bit risky and not that good to be honest. I think the better solution is using std::to_string :

unsinged char char1{192};
auto result = std::to_string(char1)

now char1 equals to std::string("192")
