**5. Control Structures: Control structures dictate the flow of a program. Common structures include:
- Conditionals: Allow the program to make decisions (e.g.,
if
,else
). - Loops: Enable the program to repeat actions (e.g.,
for
,while
).
**6. Functions: Functions are reusable blocks of code that perform specific tasks. They help organize code and make it more modular. For example, in Python, a function might be defined as follows:
pythonCopy codedef greet(name):
return f"Hello, {name}!"
**7. Error Handling: Handling errors and exceptions is crucial for creating robust programs. Programming languages provide mechanisms to handle unexpected situations and prevent crashes.
