The ____ line for any e-mail messages you write should clearly state the intention of the e-mail..
KatRina [158]

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.

Write a program that allows the user to enter a start time and a future time. Include a function named compute Difference that t
Aleonysh [2.5K]

Step 1

Following is the c++ program:

Variables used:

startHours, startMins are used to store the starting time of time machine.

futureHours, futureMins are used to store the future time of time machine.

xAM variable is used to store meridiem of start and future time.

isSAM is boolean variable that is true if starting time is AM.

isFAM is boolean variable that is true if future time is AM.

 

Functions:

main() is used to call computeDifference() function that will calculate the difference between the start and future time.

computeDifference() takes as input six variables from the user and then apply the following logic to compute the difference between the start and future time:

If Meridien of both start and future time are the same, then simply subtract the start time from the future time.

Difference = future minutes – start minutes

If Meridien of both start and future time are different, then apply the following formula to calculate difference:

Difference = (12 * 60 – start minutes) + future minutes

Step 2

Program :

#include <iostream> //header file for input and output

 

using namespace std;

//calculate the time difference(in minutes) between start time and future time.

int computeDifference(int startHours, int startMins, bool isSAM, int futureHours, int futureMins, bool isFAM) {

 int difference = 0; //to store difference

 startMins = startHours * 60 + startMins; //converting in minutes.

 futureMins = futureHours * 60 + futureMins; //converting in minutes.

 //applying formula for difference.

 if (isSAM == isFAM) {

   difference = futureMins - startMins;

 } else if (isSAM == true && isFAM == false) {

   difference = (12 * 60 - startMins) + futureMins;

 }

}

int main() {

 int startHours, startMins; //it will store start time

 int futureHours, futureMins; //it will store future time.

 string xAM; //it will store meridiem.

 bool isSAM; //it will be true if start time is AM.

 bool isFAM; //it will be true if future time is in AM.

 int difference = 0; //it will store difference.

 cout << "Enter start time of time machine as 'HH MM AM/PM': "; //take input from
