C# Control Flow

What is the purpose of if-else statements in C#?

• To make the code more readable

• To increase the speed of execution

• The purpose of if-else statements in C# is to control the flow of the program based on specified conditions.

• To add unnecessary complexity

Explain the difference between while and do-while loops in C#.

• While loop checks the condition before executing the block of code, whereas do-while loop executes the block of code at least once before checking the condition.

• While loop and do-while loop have the same syntax and functionality.

• While loop and do-while loop are interchangeable and can be used in the same scenarios.

• While loop executes the block of code at least once before checking the condition, whereas do-while loop checks the condition before executing the block of code.

How can a switch statement be used in C#?

• Switch statements in C# can only be used with integer values

• In C#, a switch statement can be used to execute different blocks of code based on the value of a given expression.

• Switch statements in C# are equivalent to if-else statements

• A switch statement in C# is used to loop through a collection of items

What is the role of the 'break' keyword in loops in C#?

• The 'break' keyword is used to pause the loop

• The 'break' keyword is used to restart the loop

• The 'break' keyword is used to skip the loop iteration

• The 'break' keyword is used to exit a loop prematurely.

Discuss the concept of nested if-else statements in C#.

• Nested if-else statements in C# are not supported by the language

• Nested if-else statements in C# are used for loop iterations

• Nested if-else statements in C# are used to handle multiple conditions in a structured manner by nesting one if-else block inside another.

• Nested if-else statements in C# can only have one condition

What are the advantages of using the 'continue' keyword in loops in C#?

• Using 'continue' keyword in loops in C# causes an infinite loop

• Using 'continue' keyword in loops in C# stops the loop entirely

• Using 'continue' keyword in loops in C# helps in skipping the current iteration and moving to the next one without executing the remaining code in the loop body.

• The 'continue' keyword in loops in C# executes the remaining code in the loop body

How can you implement a for loop in C#?

• for(int i = 0; i < n; i++) { // code block }

• for(initialization; condition; increment/decrement) { // code block to be executed }

• for(i = 0; i < n; i++) { // code block }

• for(init; condition; update) { // code block }

Explain the use of the 'return' statement in C#.

• The 'return' statement in C# is used to print a value on the console.

• The 'return' statement in C# is used to declare a variable.

• The 'return' statement in C# is used to explicitly return a value from a method.

• The 'return' statement in C# is used to loop through an array.

Discuss the importance of using 'else if' statements in C#.

• Else if statements in C# are important for handling multiple conditional cases in a structured and efficient manner.

• Else if statements in C# are only used for debugging purposes

• There is no difference between using 'else if' and 'if' statements in C#

• Using 'else if' statements in C# is optional and not recommended

What are the benefits of using ternary operators in C#?

• Using ternary operators in C# increases the complexity of the code.

• Ternary operators in C# can only be used for simple conditional statements.

• Ternary operators in C# are not supported by all versions of the language.

• Using ternary operators in C# can improve code readability and reduce the amount of code needed for simple conditional statements.
