How to Validate the Length of a String in C++

How to Validate the Length of a String in C++

Greetings, today we are here with a C++ tutorial. We shall be doing a length check validation on a string. This can be useful if you want to control the size of the user's input.

This will be a 4 part series. In this video we are covering how to check if the user has inputted a string of a specific length.

If we set the desired length to be 5, if the user inputs a word that is 4 characters long, it will be invalid. If the user inputs a word that is 5 characters long, it will be a valid input. This could be useful for when asking the user for their postcode, phone number, pin, date of birth or credit card number as these can be fixed lengths.

Thanks for watching this C++ length check tutorial.

This tutorial is aimed at beginners.
