Alot of methods that I have seen take a const char * (which also might be the 'string' that he is refering to) will loop through the variable until they hit a NULL \0 character.

This often is how 'string arrays' are ended and will usually be a good stop to calculate the string length.

The function strlen does not take a string, but an array of chars. Please see this reference for examples. If you are using the type string you will find it's length by using the function length(), like this: 

std::string text = "Some text"; 
int length = text.length();

For more examples see this other question.

string s;

declares a string named s, not an array of strings, which would be 

string array[10];

for instance. To get the length of a string, you call its size() or length() method:

size_t len = s.size();

Use the member function length().
