Now, for the final post in this mini-series, let's turn our attention to a feature that was originally scheduled for release in C# 10, but didn't quite make the cut: required properties.

💻 Capitalize the First Letter of Each Word | #easy

Create a function that takes a string as an argument and converts the first character of each word to uppercase. Return the newly formatted string.

Examples:

MakeTitle("This is a title") ➞ "This Is A Title"
MakeTitle("capitalize every word") ➞ "Capitalize Every Word"
MakeTitle("I Like Pizza") ➞ "I Like Pizza"
MakeTitle("PIZZA PIZZA PIZZA") ➞ "PIZZA PIZZA PIZZA"

For your convenience: dotnetfiddle.

Thx to Roman!

Have a great weekend and perfect first code 😉

📝 What is the difference between continue and break statements in C#?

🔸 using break statement, you can jump out of a loop

🔸 using continue statement, you can jump over one iteration and then resume your loop execution

📝 When to use Finalize vs Dispose?

🔸 The finalizer method is called when your object is garbage collected and you have no guarantee when this will happen (you can force it, but it will hurt performance).

🔸 The Dispose method, on the other hand, is meant to be called by the code that created your class so that you can clean up and release any resources you have acquired (unmanaged data, database connections, file handles, etc) the moment the code is done with your object.

The standard practice is to implement IDisposable and Dispose so that you can use your object in a using statement such as using(var foo = new MyObject()) { }.

And in your finalizer, you call Dispose, just in case the calling code forgot to dispose of you.

💻 Perfect Number | #easy

Create a function that tests whether or not an integer is a perfect number. A perfect number is a number that can be written as the sum of its factors, (equal to sum of its proper divisors) excluding the number itself.

For example, 6 is a perfect number, since 1 + 2 + 3 = 6, where 1, 2, and 3 are all factors of 6. Similarly, 28 is a perfect number, since 1 + 2 + 4 + 7 + 14 = 28.

Examples:

CheckPerfect(6) ➞ true
CheckPerfect(28) ➞ true
CheckPerfect(496) ➞ true
CheckPerfect(12) ➞ false
CheckPerfect(97) ➞ false

📝 What are Property Accessors?

The get and set portions or blocks of a property are called accessors.

These are useful to restrict the accessibility of a property.

🔸 The set accessor specifies that we can assign a value to a private field in a property and without the set accessor property it is like a read-only field.

🔸 By the get accessor we can access the value of the private field. A Get accessor specifies that we can access the value of a field publicly.
