| 46 | Word Frequency Finder |
Knowing how often a word appears in a sentence or block of text is helpful for creating word clouds and other types of word analysis. And it’s more useful when running it against lots of text.
Create a program that reads in a file and counts the frequency of words in the file. Then construct a histogram displaying the words and the frequency, and display the histogram to the screen.
Example Output
Given the text file words.txt with this content
| | badger badger badger badger mushroom mushroom |
| | snake badger badger badger |
the program would produce the following output:
| | badger: ******* |
| | mushroom: ** |
| | snake: * |
Constraint
-
Ensure that the most used word is at the top of the report and the least used words are at the bottom.
