Working with two StringsWorking with two Strings

This chapter explains how to compare, copy, and swap strings.
Let's start with

Comparing strings

You can compare strings using the == or != operators.
Those operators work pretty much as expected. One thing to note is that they are case-sensitive, so "Code" is not equal to "code".

cpp

main.cpp

There are also <, <=, >, and >= operators for strings.
They compare strings by their length first.
If lengths are equal they compare the characters of the strings based on their ASCII values.

cpp

main.cpp

Copying

To copy the string, just use the assignment operator (=):

Here is an example:

cpp

main.cpp

Swapping

You can swap the values of two strings using the .swap() method with the following syntax:

Here is an example:

cpp

main.cpp

Task

Ensure a string named shorter is shorter than longer.
If it's not true, swap their values.
