In this chapter, students learn how to control the flow of a program using different control structures in C language. It explains how to make decisions in programs using if, if-else if, and switch statements. You will also understand the use of logical operators, which help check multiple conditions at the same time. These concepts help students write programs that can make decisions and work according to different situations.

❓ FAQs – Chapter 11 Decision Constructs
Q1: What is a control structure in C language?
A control structure is used to control the flow of execution in a program based on conditions.
Q2: What is the purpose of the if statement?
The if statement is used to execute a block of code when a specified condition is true.
Q3: What is an if-else if statement?
An if-else if statement is used to check multiple conditions one by one and execute the correct block of code.
Q4: Why are logical operators used in decision constructs?
Logical operators are used to combine multiple conditions and make more complex decisions.
Q5: When should we use a switch statement?
A switch statement is used when there are many possible values of a variable and each value requires a different action.
