Sample questions

1. What is a control structure in programming?

   1. A way to manage hardware
   2. A method to build desktop applications
   3. A way to manage the flow of a program
   4. A technique to optimize code
   Show answer

   Answer: C. A way to manage the flow of a program

   Control structures are used to dictate the order of execution of the statements in a program.

2. What is the default flow of control in a program?

   1. Sequential execution
   2. Parallel execution
   3. Random execution
   4. Condensed execution
   Show answer

   Answer: A. Sequential execution

   Programs execute in a sequential order unless control structures dictate otherwise.

3. Which symbol marks the beginning of a block in most syntax?

   1. #
   2. {}
   3. ()
   4. <>
   Show answer

   Answer: B. {}

   In many programming languages, curly braces '{}' are used to define the start and end of a block of code.

4. When should 'if-else' be preferred over 'switch' statement?

   1. When there are multiple precise comparisons
   2. When dealing with a single integer
   3. When optimizing for memory
   4. When all decisions can be computed with arithmetic
   Show answer

   Answer: A. When there are multiple precise comparisons

   An 'if-else' chain is more suitable for precise or logical conditions, unlike 'switch', which is better for predefined constant values.

5. Which of the following can be used as a synonym for 'control structure'?

   1. Data handling
   2. Flow control
   3. Loop architecture
   4. Simple block
   Show answer

   Answer: B. Flow control

   Control structures are frequently referred to as flow control; they determine the path that execution will follow.
