Answer:
Following are the program in C++ language
#include<iostream> // header file
using namespace std; // namespace std
int reverse(int n1); // function prototype
int main() // main function()
{
int num; // Variable declaration
cout << "Enter the number" << endl;
cin >> num; // Read the number bu the user
cout<<"After Reverse the digit:\n";
int res= reverse(num); // calling function reverse
cout<<res; // display
}
int reverse(int n1) // function definition of reverse
{
if (n1<10) // checking the base condition
{
return n1;
}
else
{
cout << n1 % 10; // Printed the last digit
return reverse(n1/10); // calling itsself
}
}
Output:
Enter the number:
76538
After Reverse the digit:
83567
Explanation:
Following are the description of the program
- In the main function read the number by user in the "num" variable of int type.
- Calling the reverse and pass that "num" variable into it.
- After calling the control moves to the body of the reverse function.In this function we check the two condition
1 base condition
if (n1<10) // checking the base condition
{
return n1;
}
2 General condition
else
{
cout << n1 % 10; // Printed the last digit
return reverse(n1/10); // calling itsself
}
- Finally return the reverse number and display them into the main function.
