C Programming Control Flow

What is the syntax of an if else statement in C?

• if (condition) { // code to be executed if the condition is true } else { // code to be executed if the condition is false }

• if (condition) { // code to be executed if the condition is true } else { // code to be executed if the condition is false }

• if (condition) { // code to be executed if the condition is true } else { // code to be executed if the condition is false }

• if (condition) { // code to be executed if the condition is true } else { // code to be executed if the condition is false }

How can logical operators be used in if else statements in C?

• Logical operators can only be used in loops in C

• Logical operators can be used to create compound conditions in if else statements in C.

• Logical operators are not supported in if else statements in C

• Logical operators can only be used in switch statements in C

Explain the purpose of switch case statements in C.

• Switch case statements in C are used to iterate over arrays.

• Switch case statements in C are used to control the flow of the program based on the value of a variable.

• Switch case statements in C are used for mathematical calculations only.

• Switch case statements in C are used to define custom data types.

What happens if no case matches in a switch statement in C?

• The default case (if present) will be executed, otherwise the control will exit the switch statement.

• An error message will be displayed

• The switch statement will loop indefinitely

• The program will crash

How can multiple cases be handled in a single switch case in C?

• By omitting the break statement at the end of each case in the switch statement.

• By using if-else statements instead of switch case

• By adding a default case for all possible cases

• By using multiple switch statements within the same switch block

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

• To execute a specific case when none of the cases match the given expression.

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

• To terminate the switch statement when none of the cases match the given expression.

• To skip the default case and move to the next case when none of the cases match the given expression.

Can if else statements be nested in C programming?

• Rarely

• Sometimes

• No

• Yes

What is the role of the else statement in an if else block in C?

• It specifies the code to be executed if the condition in the if statement is false.

• It determines the code to be executed if the condition in the if statement is true.

• It specifies the code to be executed if the condition in the if statement is partially true.

• It is used to end the if else block.

How are if else statements different from switch case statements in C?

• If else statements can only have one condition, while switch case statements can have multiple conditions.

• If else statements are used to execute a block of code if a condition is true, while switch case statements are used to select one of many code blocks to be executed.

• If else statements are more efficient than switch case statements in terms of execution speed.

• If else statements can only handle boolean expressions, while switch case statements can handle multiple data types.

Explain the importance of break statements in switch case statements in C.

• Break statements in switch case statements are optional and can be omitted without affecting the program's behavior.

• Break statements in switch case statements help control the flow of execution by exiting the switch block after a case is matched.

• Break statements in switch case statements are used to jump to the next case without executing the current case.

• Break statements in switch case statements are used to repeat the execution of a case multiple times.
