The std::string has a data member that holds its size. Calculating the size of a string object is therefore a fast constant time operation, which is independent of the number of characters currently stored in the string object. On the other hand, the performance of strlen() is proportional to the number of characters stored in a C-string. When large strings are used and size computations are frequent, std::string is more efficient than a C-string.
