A file that data is written to is known as a(n).______.
a. input file
b. output file
c. sequential access file
d. binary file
The data that are written to a file are known as output file.
Hence, the correct answer is option “B”.
Explanation of Solution
Output file:
- A file where the data are written is called as “output file”. The output file is created on the disk and allows the program to write data on it.
- The “output file” must be accessed using the file name and must be closed after the usage of the file.
- If the file is not closed properly, it can cause loss of data because the data that are written to a file are stored in a buffer first.
- After closing a file, the buffer saves the contents into the disk.
Example for output file:
The following program is used to open an output file, write a name to it, and then close it:
#Function main
def main():
#Open an outfile for writing
outfile=open('my_name.txt','w')
#Write the name into file
outfile.write("Tom cruise")
#Close the file
outfile.close()
#Display statement
print('Data written to my_name.txt')
#Call the main function
main()
Explanation:
The above program is used to open an output file named “my_name.txt”, write a name to it, and then close it:
- In the “main()” function, open a file “my_name.txt” and write a name "Tom cruise" to the file using the “write()” method.
- Close the file using the “close()” method. Display the intimation message on the screen.
- Call the “main()” function.
Explanation for the incorrect options:
Input file:
A file from which the data are read is called as an input file. When a program gets input from the file, then it is called as input file.
Hence, option “A” is wrong.
Sequential access file:
In sequential access method, the contents of the file are accessed from the beginning to the end.
Hence, option “C” is wrong.
Binary file:
Binary file holds data that are not represented in the form of text. The executable programs are stored in the type of binary file.
- Due to this, the contents present in the binary file cannot be viewed with normal text editors.
Hence, option “D” is wrong.
Output:
Data written to my_name.txt
Screenshot of “my_name.txt” file

- Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10.
