Question

How can I add an integer variable to a string and char* variable? for example:
int a = 5;
string St1 = “Book”, St2;
char *Ch1 = “Note”, Ch2;

St2 = St1 + a –> Book5
Ch2 = Ch1 + a –> Note5

Thanks

The C++ way of doing this is:

std::stringstream temp;
temp << St1 << a;
std::string St2 = temp.str();

You can also do the same thing with Ch1:

std::stringstream temp;
temp << Ch1 << a;
char* Ch2 = new char[temp.str().length() + 1];
strcpy(Ch2, temp.str().c_str());
