Answer:
PLCs (Programmable logic controller) were original designed as replacement for relay control panels. Relay is another word for a switch. Relay control panels were made for the control of electronic instrumentents or devices. Later on PLCs were made to replace these timers and relay control panels. PLCs are more reliable, flexible and can work better in the harsh environmental situations then the relay control panels.
Answer: It arranges text in a list alphabetically from A to Z.
Explanation: It's always easier and more systematic to arrange alphabetically. With numbers there is the possibility of infinity but not with alphabet which have a defined range.
Answer:
C++ code is given below
Explanation:
#include<iostream>
#include <cstring>
using namespace std;
int housekeeping(string EOFNAME);
int mainLoop(string name,string EOFNAME);
int finish();
void main()
{
string name;
string EOFNAME = "ZZZZ";
cout << "enter the name" << endl;
cin >> name;
if (name != EOFNAME)
{
housekeeping(EOFNAME);
}
if (name != EOFNAME)
{
mainLoop(name , EOFNAME);
}
if (name != EOFNAME)
{
finish();
}
system("pause");
}
int housekeeping(string EOFNAME)
{
cout << "enter first name " << EOFNAME << " to quit " << endl;
return 0;
}
int mainLoop(string name, string EOFNAME)
{
int hours;
int rate,gross;
int DEDUCTION = 45;
int net;
cout << "enter hours worked for " << name << endl;
cin >> hours;
cout << "enter hourly rate for " << name << endl;
cin >> rate;
gross = hours*rate;
net = gross - DEDUCTION;
if (net > 0)
{
cout << "net pay for " << name << " is " << net << endl;
}
else
{
cout << "dedections not covered.net is 0.";
}
cout << "enter next name or " << EOFNAME << " to quit" << endl;
cin >> name;
return 0;
}
int finish()
{
cout << "end of job"<<endl;
return 0;
}
This is an incomplete question. The complete question is given below:
Mike has never used slide presentation software before but he needs to create a presentation by the end of the week what resource would be most helpful to mike
a. The 350-page printed manual from the slide presentation software publisher
b. A free tutorial the slide presentation software publisher has posted on the company website
c. A trouble-shooting website created by a third party
d. The 350-page online manual from the slide presentation software publisher
Answer:
b - A free tutorial the slide presentation software publisher has posted on the company website
Explanation:
As Mike has a short time and no prior experience with a slide software, then in this scenario, the best, simplest and fastest way to learn and create a presentation a free tutorial which the slide presentation software publisher has posted on the company website as this is the same company that has created this particular software so he can be rest-assured that the resource he is relying on is authentic and up-to-date with information on latest features.
Moreover, it's efficient and quick way to learn from a free tutorial rather than from 350-page printed or online manual especially for a beginner.
Besides, his purpose is to create the presentation using the software and not trouble-shooting so trouble-shooting website created by a third party is not useful for him and it also might not be authentic or updated as well.
