Creation and use of lists in Python
Creation and use of ranges in Python
On this mastery I’ll show you what are strings and how to use them in C++.
String are things that are represented by a sequence of characters.
We will create a function that works as a palindrome and tells the user if the word he input is a palindrome or not. Do as follows:
- Create a main program and leave a space before it for the function
- Create a function of type string called palindrome
- Condition the user input with VARIABLE.rbegin and VARIABLE.rend. This iterators make the string return reversed to the beginning and end. This is the Palindrome “function”
- In main(), ask the user for the input and call for the function.
Your program should look something like this:
Now let’s test it:
Great! Now you know how to do a basic program using string. If you want to learn more about strings, go to this webpage:
#Mastery25 A string means an ordered sequence of characters, and in most programming languages such strings are enclosed in either single or double quotes.
In C++ the enclosing delimiters are double quotes. IFor example, the usual first C++ program displays the string literal “Hello, world!” on the screen with the following output statement.
Strings are objects that represent characters, it is actually a one-dimensional array of characters. It is kind of like the same way you declare an array but instead you use characters. Which is the structure of a string?
char name[number of elements] ={‘a’, ‘b’, ‘c’};
or
char name[] ={“abc” };
You can represent a string the same way you represent an array.

A standard library in C++ provides a string class type.
There are other ways to declare a different type of string.
Using namespace std;
String name;
Or
Std:: string name;
A string can be also assigned to each other or appended together using the + operator.
Strings can also be found as compsrisons…
One of the most confusing part of using char*s as strings is that comparisons tricky.
Here is a simple example of the usage of a string;

I KNOW HOW TO USE RANGES IN PYTHON
HERE IS AN EXAMPLE WHERE I USE A RANGE IN PYTHON
Hey today we are going to learn how to create and use ranges in Pythons 3 : creating and using ranges #Mastery25
Here are masteries 23 and 25, about strings and vectors. Maybe the most complicated for me since I just learned how to use vectors. Enjoy: https://www.youtube.com/watch?v=llPuSsueAfY
