#include <iostream>
using namespace std;

unsigned int reverseDigits(unsigned int n) {
int i, m;
m = 0;
while (n != 0) {
m = m*10 + n%10;
n = n/10;
}
return m;
}

int main() {
unsigned int n;
cout << "Reverse digits" << endl;
cout << "Please enter a number: ";
cin >> n;
cout << n << endl;
cout << reverseDigits(n) << endl;
return 0;
}

Answer 2

#include <iostream>
using namespace std;
int main() {
long int dig,i,rev;
cout<<"Enter the digit\t:: ";
cin>>dig;

// reversing digit

cout<<"The reversed digit is \t:"<<endl;
for(i=1;dig!=0;i*=1){
rev=dig%10;
dig/=10;
cout<<rev;
}
return 0;
}

Answer 3

u can simple use string functions to reverse digits

Answer 4

u want to reverse string or numbers?

Answer 5

Let getReversedNumber(N) is a function, which returns reverse of N. Then, we can use recursion to reverse the digits if a number using below mention recursive equation.
getReversedNumber(N) = (N%10)X pow(10, (log10(N/10) + 1)) + getReversedNumber(N/10)

Here is the c program to reverse a number using recursion

Reversing a number using loop

while(number != 0){
rightDigit = number % 10;
reverse = (reverse * 10) + rightDigit;
number = number/10;
}

Answer 6

#include<iostream.h>
int maun()
{
int a=5,i;

for(i=0;i<=a;i++)
{
cout<<a<<endl;
a--;

}

return 0;
}
