WAP in C++ to swap first and last digits of any number.

C++ Program

WAP to swap first and last digits of any number. (For ex:-n=12345, Output:-52341)

CODE:

#include <iostream>

#include <math.h>

using namespace std;

int main()

{

int n, first, last, sum, digits, nn, a, b;

cout <<"\n\n Find the number after swapping the first and last digits:\n";

cout <<"-------------------------------------------------------------\n";

cout <<" Input any number: ";

cin >> n;

digits =(int)log10(n);

first = n /pow(10, digits);

last = n %10;

a = first *(pow(10, digits));

b = n % a;

n = b /10;

nn = last *(pow(10, digits))+(n *10+ first);

cout <<" The number after swaping the first and last digits are: "<< nn << endl;

}
