I have been using std::string in my code. I was going to make a std::string and pass it by reference. However, someone suggested using a char * instead. Something about std::string is not reliable when porting code. Is that true? I have avoided using char * as I would need to do some memory management for it. Instead I find using the std::string much easier to use.
Basically I have a 10 digit output that I am storing in this string. Atm, I am not sure which would be better to use.
In C++, almost every string should be std::string unless another library requires a cstring, in which case you should still be using an std::string and passing string.c_str(), unless you’re using functions that work with buffers.
However, if you’re writing a library and exporting functions, it’s better to use const char* parameters rather than std::string parameters for portability.
