Chapter 6, Problem 1MC

Program Description Answer

The data that are written to a file are known as output file.

Hence, the correct answer is option “B”.

Expert Solution & Answer

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.

Sample Output

Output:

Data written to my_name.txt

Screenshot of “my_name.txt” file
