Question

I need to revise a c++ code that asks to: enter up to 5 digits positive integer number, then reverse the order of the digits. The program outputs both numbers and calculates their square roots in the following way

Please enter a 5-digits integer: ( inputs 56789) output as follow

The square root of 566789 is:
The number in reverse is: 98765
The square root of the reversed number 98765 is:

Answer 1

CODE FOR THE PROBLEM

1 #include<iostream>

2 #include<math.h> // for calculating square root

3 using namespace std;

4 int main()

5 {

6 int num;

7 cout<<"enter upto 5 digit integer "<<endl;

8 cin>>num; // taking input of number

9 int q=num,r; // storing number in q

10 int num2=0; // declaring num2 to store reverse of num

11 while(q!=0) // begin of while loop

12 {

13 r=q%10;

14 q=q/10;

15 num2=num2*10+r;

16 } // end of while loop

17 // sqrt is used to find square root.

18 cout<<"The square root of "<< num <<" is: "<<sqrt(num)<<endl;

19 cout<<"The number in reverse is: "<<num2<<endl;

20 cout<<"The square root of the reversed number "<< num2 <<" is: "<<sqrt(num2)<<endl;

21 }

22

23

24 /** while loop is used here to reverse the number , every time the number is

25 divided by 10 and the remainder is stored in num2 and the quotient becomes new

26 q so that the number can be reversed .**/

Screenshot is below

#include<iostream> #include<math.h> using namespace std; int main( { // for calculating square root int num; cout<<"enter upto 5 digit integer "<<endl; cin>>num; int q=num, r; int num2=0; while ( q ! = 0) { r q%10; q=q/10; num2 num2*10+r; 7 taking input of number / storing number in q // declaring num2 to store reverse of num / begin of while loop // end of while loop / sqrt is used to find square root. cout<<"The square root of "<< num <<" is: "<«sqrt(num) <<endl; cout<<"The number in reverse is: "<<num2<<endl; cout<<"The square root of the reversed number "<< num2 <<" is: "<<sqrt (num2 ) <<endl; } **while loop is used here to reverse the number divided by 10 and the remainder is sto red in num2 and the quotient becomes n ew q so that the number can be revesed.**/ , every time the number is scree shot of code
