A sentence or a paragraph without suitable punctuation marks does not give clarity to the meaning to a piece of writing, therefore, the function of marks of punctuation in a sentence or in a paragraph is very important. Without the use of proper punctuation marks, the writer fails to convey the proper meaning of the text. Read these examples to know how the use of punctuation marks alters the meanings of these two sentences:
The use of capital letters
The full stop is used to mark the end of a statement or an imperative sentence. It indicates the greatest pause and separation of one sentence from the other.
We use full stop:
a. at the end of all assertive and imperative sentences:
b. in abbreviations and initials: B.K. Chawla, (Baljeet Kumar Chawla) M.Com., N.C.C., H.U.D.C.O.
c. to indicate a decimal fraction: (It is read as 'point'.) 112.25, 91.70
The comma represents the shortest pause or break between parts of a sentence. It is used to:

b. set off a common noun or a proper noun of address: Will you help me, sir? (sir - common noun) Makrand, prepare a list of successful candidates. (Makrand-proper noun.)
c. when a very brief pause is needed: To meet his friend in jail, he took the assistance of the jailor. Do not hire a taxi, walk on foot.
d. indicate affirmative and negative expressions: Yes, ours was the best performance. No, they were not called on the stage.
e. express expressions like oh, well: Oh, we are sorry for our misbehaviour. Well, you are permitted to leave the room. ' ' is variant of 'oh'. 0 is used to introduce an invocation, entreaty, or the like in religious and literary contexts.
f. separate expressions like too, however, in fact: My sister, too, has many credentials to her credit. The weather is cold, however, she still thinks she should swim. The saint, in fact, is the accused himself.

The mark of exclamation is used after interjections, exclamatory phrases, exclamatory sentences and optative sentences. Alas! We have lost grandfather. What a hot cup of tea it is!
The quotation marks, also known as the inverted commas, are used to enclose the exact words of speaker or a quotation. Atul said, "My choicest career is to join Indian army." "Necessity is the mother of invention." The sign of quotation mark is always put after the full stop, the question mark and the exclamation mark.
