Selection Control Structure in Programming Fundamentals

What is the purpose of the 'if' statement in programming?

• Defining functions

• Printing output

• Looping

• Conditional execution

When is the 'else' statement executed in relation to the 'if' statement?

• When the 'if' statement is not present

• When the condition in the 'if' statement is true

• When the 'if' statement is commented out

• When the condition in the 'if' statement is false

Explain the concept of nested if-else statements in programming.

• Nested if-else statements can only have one if statement inside another.

• Nested if-else statements are used to create loops in programming.

• Nested if-else statements provide a way to handle complex decision-making scenarios by nesting one if-else statement inside another.

• Nested if-else statements are not supported in most programming languages.

What is the advantage of using a switch case statement over multiple if-else statements?

• Switch case statements are less flexible.

• Switch case statements are harder to read and understand.

• Switch case statements are more efficient.

• Switch case statements are not supported in all programming languages.

In an 'if' statement, what happens if the condition is false?

• The 'if' statement will skip to the next line of code.

• The 'if' statement will throw an error.

• The code block inside the 'if' statement will not be executed.

• The code block inside the 'if' statement will be executed twice.

How many 'else' statements can be associated with a single 'if' statement?

• 4

• 1

• 3

• 2

What is the syntax for a nested if-else statement in most programming languages?

• if (condition1) { if (condition2) { // code block } else { // code block } } else { // code block }

• if (condition1) { if (condition2) { // code block } else { // code block } } else { // code block }

• if (condition1) { if (condition2) { // code block } } else { // code block }

• if (condition1) { if (condition2) { // code block } else { // code block } else { // code block }

What is the default case used for in a switch case statement?

• To execute a specific case when no other cases match

• To handle the scenario when none of the cases match the given expression.

• To skip the switch case statement entirely

• To provide an alternative expression for the switch case

What happens if none of the cases in a switch case statement match the given value?

• An error message is displayed

• Default case (if present) will be executed, otherwise program moves to the next line of code outside the switch statement.

• The switch statement repeats indefinitely

• The program crashes

Can a switch case statement be used with strings as cases?

• Yes

• Maybe

• Sometimes

• No
