The item that you would most likely to keep in a database is a Payroll record. Payroll records are numbers and inputs/outputs of employees of a certain company. Numbers are easier to manipulate and easier to manage than statements, letters and addresses that are basically letters.
Let me re-write the proposition:
p↔q⊕(¬p↔¬r)∧¬q.
Generally, the number of rows in a truth table depends on the number of Variables. Here we have 3 Variables: p,q and r. Each of them can have either the value of 1 or 0, which gives us 2*2*2 possibilities, or 2³, that is 8 possibilities and 8 rows:
p=0, q=0, r=0
p=0, q=0, r=1
p=0, q=1, r=0
p=0, q=1, r=1
p=1, q=0, r=0
p=1, q=0, r=1
p=1, q=1, r=0
p=1, q=1, r=1
The <u>subject </u>line for any e-mail messages you write should clearly state the intention of the e-mail.
Electronic mail (e-mail) is a method of digital communications in which messages are exchanged through the internet. The messages are sent from a sender to one or more receivers. Depending on user’s perspective, every user uses e-mail differently. Communicating via e-mail requires e-mail platforms such as G*mail, Ya*hoo! Mail, Hot*mail, and Out*look etc. In the every e-mail, there is a subject line that clearly state the intention of the e-mail.
Subject line is an important element of an e-mail. Through the subject line, the message written in the e-mail is briefly summarized in six to eight words. A clearly written subject line provides the recipient a clear understanding that why the email has been sent. When recipient replies back to the e-mail, the subject line is changed accordingly.
This is the subject line of the e-mail that convince the receiver whether to open and read the e-mail. So, it should be written in the way that gives clear intention of the e-mail. We can say that the subject line of the e-mail is the most significant few words in the whole e-mail to convey the main purpose of the e-mail.
