Control Structure in C language

A control structure is a block of code that manages the flow of execution in a program.

Control structures dictate the order in which statements are executed based on certain conditions.

Types of control structures:

1. Sequential Structure
2. Selection Structure (Conditional Statements)
3. Repetition Structure (Loops)

Let’s see each of them in brief:

Sequential Structure

• The default structure is where statements are executed one after the other in sequence.
• Example:

Sequential Structure

Selection Structure (Conditional Statements)

• Allows the program to make decisions and execute different blocks of code based on specified conditions.
• All conditional statements available in C language are mentioned below:

1. if statement
2. if else
3. ladder
4. nested
5. ternary
6. switch case

• Let’s see the syntax of each of them:

Syntax of if statement

Syntax of if else statement

Syntax of a ladder if else statement

Syntax of a nested if else statement

Syntax of ternary conditional statement

Syntax of a switch case statement

Repetition Structure (Loops):

• Allows the execution of a block of code repeatedly as long as a specified condition is true.
• Types of loops in C language are mentioned below:

1. Entry Controlled Loop: while loop, and for loop
2. Exit Controlled Loop: do while loop

• Let’s see the syntax of each of them:

Syntax of a while loop

Syntax of a do while loop

Syntax of for loop
