$18\mathrm{.}32\mathrm{.}1$: PRACTICE: Loops$**$: Word count

Many text processing tools like Microsoft Word or Google Docs will count the number of "words" in text. A word is a sequence of any characters other than a space. Write a program that reads an input line of text, and outputs the number of words in that text. If the input is "I have a bike." then the output is $4.$

Hints:

in c$++$

Use getline to read the line of text

Use a for loop to walk through each character in the string. Count the words as you go through that loop. You'll need a variable to keep that count. Initialize it to $0$ before the loop, and then increment it whenever you see a new word.

Use a boolean variable to indicate whether you are currently $"$in$"$ a word or not. If you see a space, set that variable with false. Else, set it to true.

There are actually three cases to consider in each loop iteration. Either you are at a space $($so are not in a word$),$ you are not at a space and you are NOT already in a word $($so you found a new word$),$ or you are not at a space and you ARE already in a word $($so there's nothing to do$).$ So create an if $--$ else if $--$ else branch statement.
