How to get the number of characters in a std::string?

Question

How should I get the number of characters in a string in C++?

Answer 1

if you're using std::string, there are two common methods for that:

std::string Str("Some String");
size_t Size = 0;
Size = Str.size();
Size = Str.length();

if you're using the C style string (using char * or const char *) then you can use:

const char *pStr = "Some String";
size_t Size = strlen(pStr);
