cstring library

Question 1

Can you use cstring library functions on std::string objects?

Answer 1

No.

The library functions only work on c-strings. You would have to convert std::string objects to c-strings first.

Question 2

What does the strlen() function do?

Answer 2

Returns the length of a string.

It only returns the number of characters between the beginning of the string and the null character regardless of how large the c-string’s actual capacity is.

Question 3

What parameter(s) does strlen take?

Answer 3

strlen() takes a single c-string as its parameter.
