26_Reading Sentences - cin.get() & cin.getline().cpp

// DATE: 02-07-2023
/* PROGRAM: 26_Reading Sentences - cin.get() & cin.getline()
Read a sentence/paragraph and store it using cin.get() and cin.getline()
INPUT
This is a paragraph
ends with a dollar. $

OUTPUT
This is a paragraph
ends with a dollar.

EXPLANATION
-
- cin.get() reads a single character and use a loop to read characters till you get a new line '\n'
- cin.getline() is a inbuilt function which takes input for character arrays and we can specify the delimiter.
