Question

File Letter Counter

Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Use Notepad or another text editor to create a sample file that can be used to test the program.

Answer 1

The solution code is written in Python.

1. fileName = input("Enter file name: ")
2. target = input("Enter target character: ")
4. with open(fileName, "r")as reader:
5. content = reader.read()
6. print(content.count(target))

Step-by-step explanation:

Firstly, use input() function to prompt user for a file name. (Line 1)

Next, we use input() function again to prompt user input a target character (Line 2)

Create a reader object and user read() method to copy entire texts from to the variable content (Line 4 - 5).

At last we can get the number of times the specified character appears in the file using the Python string built-in method count() (Line 6)
