Which statement about program control in C++ is TRUE?

• Program control only manages the sequence of function calls

• Program control can alter the order in which statements are executed

• Program control is used solely for looping structures

• Program control only affects the flow of main() function

What does a selection statement allow a program to do?

• To repeat a set of instructions a specific number of times

• To decide which of several actions to take based on a condition

• To terminate the execution of a loop or function

• To store values that will be used in later operations

Which characteristic distinguishes a switch statement from an if statement in C++?

• An if statement is less versatile than a switch statement for multiple options

• An if statement can only evaluate simple conditions

• A switch statement can evaluate complex boolean expressions

• A switch statement is restricted to comparing integral values

Which of the following operators is used to check for equality in a C++ conditional statement?

• =

• ==

• &&

• ||

Which selection structure allows you to evaluate multiple conditions, where each condition can lead to a different block of code being executed?

• if

• switch

• for

• while

Which of the following is NOT a valid condition to be used in a switch statement in C++?

Which operator combination is correctly used to check if two conditions are both true in a C++ if statement?

• &&

• ||

• ==

• ><

Why might nested if statements be preferred over a switch statement in certain C++ scenarios?

• Because nested if statements are simpler to write and understand

• Because nested if statements are inherently faster

• Because nested if statements consume less memory

• Because nested if statements can handle more complex conditions

Which of the following conditions would you use to check if a variable age is between 12 and 17 inclusive?

• age > 12 && age < 17

• age < 12 || age > 17

• age >= 12 && age <= 17

• age == 12 || age == 17

What is the primary purpose of an if-else statement?

• To repeat a set of statements until a condition is met

• To choose between two alternative blocks of code based on a condition

• To decide the number of times a block of code is executed

• To exit a loop
