Answer:
The solution code is written in Python.
- fileName = input("Enter file name: ")
- target = input("Enter target character: ")
-
- with open(fileName, "r")as reader:
- content = reader.read()
- print(content.count(target))
Explanation:
Firstly, use <em>input() </em>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 <em>read() </em>method to copy entire texts from to the variable<em> content </em>(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 <em>count() </em>(Line 6)
