Strings in C and Strings in C++ are the same. And they are not basic data types. Strings in C and Strings in C++ are constructed as an array of characters. Because of this a character pointer also can be used for handling strings. Handling strings either as character arrays or character pointers requires a good understanding of the C programming fundamentals.

In this video, we've explored some important concepts behind strings in C and strings in C++. Also, we have some interview questions and answers for freshers as well as interview questions and answers for experienced candidates.

Topics covered: Strings in C, Strings in C++, strlen, and similar string library functions, How sting library functions in C are relying on the null termination byte, sizeof vs strlen, pointer to string in C, pointer to string in C++, string literal, string initialization in C by concatenating string literals.

More importantly, all these topics are explained with example programs that are basic for all string related coding questions in C++ and C.
