Control structures are fundamental building blocks in programming that dictate the flow of execution in a program. They allow developers to make decisions, repeat actions, and manage program logic efficiently. Here's an overview of common control structures:
Conditional Statements
Conditional statements execute code based on whether a condition is true or false.
- If-Else: Executes a block of code if a condition is met; otherwise, it runs an alternative block.
- Switch Case: Evaluates an expression and executes different blocks of code depending on the value.
- Ternary Operator: A concise way to write simple if-else logic.
Loop Structures
Loops enable the repeated execution of a block of code.
- For Loop: Iterates over a sequence or a range of numbers.
- While Loop: Repeats as long as a condition is true.
- Do-While Loop: Executes at least once before checking the condition.
Jump Statements
Jump statements alter the normal flow of program execution.
- Break: Exits a loop or switch statement immediately.
- Continue: Skips the current iteration of a loop.
- Return: Exits a function and optionally returns a value.
