I'm writing a program which prompts the user to enter a sentence and then prompt the user to enter a single letter of the alphabet (into a char value). It's also supposed to count and display the number of words containing the letter entered (not case sensitive) and the total number of occurrences of the letter entered (not case sensitive). An example if the user entered the sentence: 'She sells seashells by the seashore.' and the letter 'S', the output from the program would be:
4 words contain the letters S.
8 S are found in the sentence.
