Answer:
// program in C++.
#include <bits/stdc++.h>
using namespace std;
int main() {
// variable
int num;
cout<<"Enter the number between 20 and 98: ";
// read number
cin >> num;
while(num<20||num>98)
{
cout<<"Wrong input!!enter number between 20-98 only:";
cin>>num;
}
cout<<"The output is: ";
while(num % 10 != num /10)
{
// print numbers.
cout<<num<<" ";
// update num.
num--;
}
// display the number.
cout<<num<<endl;;
return 0;
}
Explanation:
Read a number from user and assign it to variable "num".Check if entered number is in between 20-98 or not.If input number is less than 20 or greater than 98 then ask again to enter a number between 20-98 until user enter a valid input.Then print the countdown from input number till both the digit of number are same.
Output:
Enter the number between 20 and 98: 99
Wrong input!!enter number between 20-98 only:12
Wrong input!!enter number between 20-98 only:93
The output is: 93 92 91 90 89 88
Enter the number between 20 and 98: 77
The output is: 77

The code is tested and is correct. If you put a semi colon ' ; ' at the end of every statement then your answer will be calculated but matlab doesn't show it until you ask i.e. typing the variable (Va, Vb, Vc )and press enter.

A tool in administrative tools which you should open if you want to view messages to troubleshoot errors is an: b. event viewer.
<h3>What is an operating system?</h3>
An operating system (OS) can be defined as a system software that's usually pre-installed on a computing device by the manufacturers, so as to manage random access memory (RAM), software programs, computer hardware and all user processes.
<h3>What is an
event viewer?</h3>
An event viewer can be defined as an administrative tool that is found in all versions of Windows Operating System (OS) which is designed and developed to enable administrators and end users in viewing the event logs of software application and system messages such as errors on a local or remote machine.
In this context, we can reasonably infer and logically deduce that an event viewer is a tool in administrative tools which you should open if you want to view messages to troubleshoot errors.
