FAQs on C++ Programming Tutorials - Tips for File Handling Video Lecture - Learn to Program with C++: Beginner to Expert - Back-End Programming
| 1. What is file handling in C programming? |  |
Ans. File handling in C programming refers to the process of creating, reading, updating, and deleting files on a computer's storage. It involves using various file handling functions and data types to perform operations on files, such as opening, closing, reading, and writing data to and from files.
| 2. How do you open a file in C programming? | |
Ans. To open a file in C programming, you can use the fopen() function. It takes two arguments: the name of the file to be opened and the mode in which the file should be opened. The mode can be "r" for reading, "w" for writing (creates a new file or overwrites an existing file), "a" for appending (creates a new file or appends to an existing file), or "r+" for both reading and writing.
| 3. How do you read data from a file in C programming? | |
Ans. To read data from a file in C programming, you can use the fscanf() function. It takes three arguments: the file pointer, the format specifier, and the address of the variable where the read data should be stored. The format specifier specifies the data type of the data to be read from the file.
| 4. How do you write data to a file in C programming? | |
Ans. To write data to a file in C programming, you can use the fprintf() function. It takes three arguments: the file pointer, the format specifier, and the data to be written to the file. The format specifier specifies the data type of the data to be written. You can also use the fputs() function to write a string to a file.
| 5. How do you close a file in C programming? | |
Ans. To close a file in C programming, you can use the fclose() function. It takes one argument: the file pointer of the file to be closed. Closing a file is important to release the resources associated with the file and to ensure that all the data is written to the file before closing it.
