Quiz on Strings in C++
String is one of the most important and confusing topics in C++. Strings are used to store sequences of characters(text). However, a string variable is a collection of characters. You may still need to revise the concepts if you feel that you need to, so please visit the tutorial first and then come to this page to check them. You will need to move forward to the arena of our quiz once you have the confidence.
Let’s get started with the C++ String quiz. Good luck!
