Course Description

Overview

Module 1: Learn the difference between many data types, how they work, what they do, and how to choose one over another.

In this module, you will:

Learn the fundamental differences between value types and reference types.
Describe the properties of many new numeric data types, including new integral types and floating point types.
Write code that returns the maximum and minimum values that numeric data types can store.
Use the new keyword to create new instances of a reference type.
Determine which data type you should choose for a given application.

Module 2: Take control of the data in your applications, knowing when to apply the correct technique to change data types as needed.

In this module, you will:

Use the casting operator to cast a value into a different data type.
Use conversion methods to convert a value into a different data type.
Guard against the loss of data when performing a cast or conversion operation.
Use the TryParse() method to safely convert a string into a numeric data type.

Module 3: Use powerful helper methods to manipulate and control the content of arrays.

In this module, you will:

Sort and reverse the order of array elements.
Clear and resize the elements of an array.
Split a string into an array of strings or characters (chars).
Join array elements into a string.

Module 4: Use C# to format strings with white space, special characters, padding, and alignment. Give context to numeric data like currency, percentages, and numbers with decimals.

In this module, you will:

Use character escape sequences to add tabs, new lines, and Unicode characters to our strings
Create verbatim string literals, and escape common characters like backslash and double-quotes
Merge templates with variables using composite formatting and string interpolation
Include various format specifiers for percentages, currency, and numbers

Module 5: Use built in methods to extract, remove, or replace data in strings.

In this module, you will:

Identify the position of a character or string inside of another string
Extract portions of strings
Remove portions of strings
Replace values in strings with different values
