Why file handling is required in C - Quick Recap

Recall & Review

beginner

What is file handling in C?

File handling in C is the process of creating, reading, writing, and closing files to store data permanently on disk.

beginner

Why do we need file handling instead of just using variables?

Variables store data temporarily in memory and lose it when the program ends. File handling allows data to be saved permanently for later use.

beginner

Give a real-life example where file handling is useful.

Saving user information like names and scores in a game so that the data is available even after the game is closed.

beginner

What happens if you don't use file handling for data that needs to be saved?

The data will be lost once the program stops running because it is only stored temporarily in memory.

beginner

Name two common operations you can do with files in C.

Reading data from a file and writing data to a file.

Why is file handling important in C programming?

A To make the program run faster

B To store data permanently on disk

C To use more memory

D To avoid using variables

File handling allows data to be saved permanently, unlike variables which lose data when the program ends.

What happens to data stored in variables when the program ends?

A It is saved permanently

B It is copied to another program

C It is sent to the printer

D It is lost

Variables store data temporarily in memory, so data is lost when the program stops.

Which of these is NOT a file handling operation?

A Opening a file

B Reading from a file

C Printing to screen

D Writing to a file

Printing to screen is an output operation, not related to file handling.

What is a real-life use of file handling?

A Saving game scores

B Changing screen color

C Running the program faster

D Making variables bigger

Saving game scores is a common example where file handling stores data permanently.

Which statement is true about file handling?

A It helps keep data after the program ends

B It deletes all data automatically

C It only works with images

D It replaces variables completely

File handling helps save data permanently so it can be used later.
