Answer:
backup() {
read dirname;
if [[ whereis . /`$dirname` 2> sterr.exe]]

Explanation:
The bash script above is used to backup C++ source files in a directory to a backup directory which is created if it does not exist, and copy's each .cpp file to backup, then sends a message to declare its completion.
Answer:
//here is code in c++.
#include <bits/stdc++.h>
using namespace std;
int main()
{
// variable
int temp;
cout<<"Please enter the temperature:";
//read temperature from user
cin>>temp;
int n;
// reduce the case for switch
n=temp/10;
// print output according to the switch case
switch (n) {
case 7:
case 6:
cout<<"tennis"<<endl;
break;
case 5:
case 4:
cout<<"golf"<<endl;
break;
default:
if(temp>=80)
cout<<"swimming"<<endl;
else
cout<<"skiing"<<endl;
break;
}
return 0;
}
Explanation:
Read the value of temperature from user and assign it to variable "temp".
Calculate n=temp/10, to limit the number of cases in the switch statement.
if temperature is greater or equal 60 & less than 80, it will print "tennis".
If temperature is greater or equal 40 & less than 60, it will print "golf".
in default case, if temperature is greater than 80, it will print "swimming".
if less than 40, print "skiing".
Output:
Please enter the temperature::67
tennis
Answer:
In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is then forced through the indoor evaporator coil or cooling compartment. The indoor unit's fan circulates the inside air to pass across the evaporator fins.
