FAQs on C++ Control Structures - 2 Video Lecture - Crash Course for EmSAT Achieve

1. What are control structures in programming?
Ans. Control structures in programming are statements that determine the flow of execution in a program. They allow programmers to control the order in which statements are executed based on certain conditions or loops.
2. How many types of control structures are there in programming?
Ans. There are three main types of control structures in programming: sequential control, selection control, and repetition control. Sequential control structures execute statements in a sequential order, selection control structures execute statements based on certain conditions, and repetition control structures repeat a set of statements until a condition is met.
3. What is the purpose of using control structures in programming?
Ans. The purpose of using control structures in programming is to control the flow of execution in a program. They allow programmers to make decisions, perform different actions based on conditions, and repeat a set of statements multiple times. Control structures help in creating more efficient and flexible programs.
4. Can you give an example of a selection control structure?
Ans. Yes, an example of a selection control structure is the if-else statement. It allows the program to execute different statements based on whether a certain condition is true or false. For example: ``` if (x > 0) { // Execute statements if x is greater than 0 } else { // Execute statements if x is less than or equal to 0 } ```
5. How does a repetition control structure work in programming?
Ans. A repetition control structure, also known as a loop, allows a set of statements to be repeated until a certain condition is met. There are different types of loops, such as the for loop, while loop, and do-while loop. The condition is checked before each iteration, and if it is true, the statements inside the loop are executed. The loop continues until the condition becomes false.
