What does casting refer to in C#?
Explicit conversion of a value from one data type to another.
How does method overloading contribute to code flexibility?
It permits defining multiple methods with the same name but different parameter lists.
What do jagged arrays consist of in C#?
Arrays where each element is an array of different lengths.
What does the params keyword allow in C#?
It enables passing a variable number of arguments to a method without explicitly creating an array.
Why is understanding argument promotion and casting crucial in C# programming?
To ensure type safety and avoid unexpected behavior in code.
What is short-circuit evaluation in C#?
A technique to optimize code by stopping the evaluation of a logical expression as soon as the result can be determined
In logical AND operations (&&) in C#, when does short-circuit evaluation occur?
When the left operand evaluates to false
What is the purpose of the static keyword in C#?
To declare members that belong to the class itself rather than instances of the class
How are static members accessed in C#?
Directly using the class name
What kind of values can const variables hold in C#?
Values that cannot be changed once assigned
Why are static classes used in C#?
To provide utility functions and constants without needing instances of the class
Learn about short-circuit evaluation in C# where logical expressions halt evaluation once a result is determined. Understand how && and || operators work based on the left operand's value.
