Null character
Jun 5, 2013 at 4:25pm
Character strings in C++ are automatically terminated by null character. Explain how this feature helps in string manipulations.

This feature allows to determine the actual size of a string.

It doesn't help, C++ strings would be manipulated just fine without that extra character. It helps the code that expects a C string to work, given a pointer to a character in a C++ string.

Really? Because it's worded exactly like a question in a homework assignment, or an exam, or a test.

@SameerThigale - Are you asking Cubbi? Please use @Cubbi if you're not responding to the OP.
As Cubbi implied, std::string keeps track of of how long a string is, so the trailing null character is not required. Any operation on (manipulation of) std::string objects implicitly knows how long each string object is. This is not true of C character strings.

I am mostly pointing out the ambiguity in the question: both C++ strings and string literals are "automatically terminated by null character", and both hold strings of characters.
