Why do we use string in C++?

C++ provides programmers to use strings to make use of text wherever needed. Strings can be printed on screen, reversed, concatenated (i.e. joined), passed to a function, etc. Since C code can be run on C++ compiler, we can use C style strings in C++.

What is the data type for string in C++?

The std::string type is the main string datatype in standard C++ since 1998, but it was not always part of C++. From C, C++ inherited the convention of using null-terminated strings that are handled by a pointer to their first element, and a library of functions that manipulate such strings.
