<div style="color:#000000;">'''Tuples'''</div>
||
* <div style="color:#000000;margin-left:1.27cm;margin-right:0cm;">Tuple is a compound data type</div>
* <div style="color:#000000;margin-left:1.27cm;margin-right:0cm;">It is a group of values of different types, stored in a single variable.</div>
* <div style="color:#000000;margin-left:1.27cm;margin-right:0cm;">Tuples have a fixed length - once declared they cannot grow or shrink in size.</div>

<div style="color:#000000;">Press Ctrl+s</div>
|| <div style="color:#000000;">We have declared a variable called '''person''' with three different data types.</div>

<div style="color:#000000;">Here the tuple is declared with floating-point, integer and boolean data type.</div>

<div style="color:#000000;">We can access tuple elements using dot notation followed by the index of the element.</div>

<div style="color:#000000;">0 for the first element, 1 for the second, and so on.</div>

<div style="color:#000000;">'''Destructuring''' means it <span style="background-color:#ffffff;">breaks the tuple into individual variables.</span></div>

<div style="color:#000000;">Here, salary<span style="background-color:#ffffff;"> becomes "</span>18000<span style="background-color:#ffffff;">", age becomes 30, and status becomes “true”</span></div>

<div style="color:#000000;">Struct</div>

* <div style="color:#000000;margin-left:1.27cm;margin-right:0cm;">Structs are similar to tuples</div>

<div style="color:#000000;">Press Ctrl+s</div>
|| <div style="color:#000000;">Here’s an example of a struct.</div>

<div style="color:#000000;">We define a struct named '''User.'''</div>

<div style="color:#000000;">The fields with their names and data types are specified within the curly braces.</div>

<div style="color:#000000;">It groups together multiple pieces of data related to a user account.</div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;"></div>

<div style="color:#000000;">'''user1''' is a variable of type '''User'''.</div>

<div style="color:#000000;">'''User '''creates an instance of the '''User struct '''and assigns it to '''user1''' variable.</div>

<div style="color:#000000;">We have the flexibility to assign key value pairs in any order, as struct is just a template.</div>

<div style="color:#000000;">To get a specific value from a struct, we use dot notation.</div>

<div style="color:#000000;">For example, to access this user’s email address, we use '''user1.email'''</div>

<div style="color:#000000;">Save the program.</div>

<div style="color:#000000;">} </div>

<div style="color:#000000;">Press Ctrl+s</div>
|| <div style="color:#000000;">We define a struct named Rectangle with two fields: width and height, both of type u32.</div>

<div style="color:#000000;">We use an impl( '''implementation''')block to implement methods for the Rectangle struct.</div>

<div style="color:#000000;">Inside the impl block, we define a method named area that calculates the area of the rectangle.</div>

<div style="color:#000000;">'''&self '''means it borrows the Rectangle instance immutably.</div>

<div style="color:#000000;">self.width and self.height are the fields of the rectangle instance.</div>
