Answer:
// program in C++.
// headers
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// Variable
int num;
cout << "Enter a number between 1 and 10: ";
// read input

// validate input number
while(num<1||num>10)
{
// if input is wrong then print error message

Explanation:
Read a number from usr and assign it to variable "num". If the input number is less than 1 or greater than 10 then ask again to enter a number until user enter a number between 1-10 only.Then with the help of switch() function print the equivalent Roman number.
Output:
Enter a number between 1 and 10: -5
Wrong input!!Enter again:12
Wrong input!!Enter again:6
The Roman numeral for 6 is:VI

Answer:
MS access objects help the user list , information and designed reports .
Explanation:
MS access objects are create a forms, data base, tables,queries, and modules. There are many objects are following:-Tables, Forms,Reports, Queries.
Table:- These are objects used into a define and store the data,tables are contain the columns and the store of different data.
Form:- Form is the object that designed by the data input and control application queries or tables, forms are used in viewing records.
Reports:- Reports are the designed to the printing and calculating data,reports are used because data in read to easy format.
Queries:- Queries are provides that data from one or more table,you can define the update ,delete, insert, select data.
Answer:
#include <iostream>
using namespace std;
int main(){
int arr1[5], arr2[5], k = 7;
arr1 = {1,3,5,3,6}
arr2 = {1,3,2,4,4}
int reverseA2[5];
for (int x = 5; x > 0; x++){
reverseA2[5-x] = arr2[x-1];
}
for (int i = 0; i < 5; i++){
if ( arr1[i] + reverseA2[i] < k){
cout<< arr1[i] << " , "<<reverseA2[i];
}
}
}
Explanation:
The C++ source code prints a pair of values from the arr1 and reverse arr2 arrays whose sum is less than the value of the integer variable value k.
