$7\mathrm{.}10$ LAB: Acronyms

An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is

an acronym of the input. Append a period $(.)$ after each letter in the acronym. If a word begins with a lower case letter, don't include that

letter in the acronym. Assume the input has at least one upper case letter.

Ex: If the input is:

Institute of Electrical and Electronics Engineers

the output is:

I.E$.$E$.$E$.$

Ex: If the input is:

Association for computing MACHINERY

the output is:

A$.$M$.$

Although the letters $\frac{A}{C}HI$ NERY in MACHINERY are upper case, those letters are omitted for being a part of the word MACHINERY.

Hint: Use isupper$()$ to check if a letter is upper case.
