Task 1: Character Search
Write a program that reads a sentence from the user and then proceeds to ask the user to enter a character. Your program should then search for words in the sentence that start with the entered character and display them along with the number of words starting with that character.
Sample Interaction:
Enter a sentence: Hello World, this is Tom Clancy!
Enter a character: t
Words starting with 't' in the sentence are: this Tom
Number of words starting with 't': 2
