Question

I am searching a std::string for certain letters so I am using:

for (int i = 0; i < word.length; i++)
...

But I then get the error:

Error 2 error C3867: ‘std::basic_string<_Elem,_Traits,_Alloc>::length’: function call missing argument list; use ‘&std::basic_string<_Elem,_Traits,_Alloc>::length’ to create a pointer to member

So I put:

for (int i = 0; i < &word.length; i++)
...

And then get the error:

Error 2 error C2276: ‘&’ : illegal operation on bound member function expression

How can I fix this and search the string? Thanks in advance.

Answer 1

You’re just missing the () after length.

std::string::length() is a function which has no parameters.
