Write a C++ Program to Swap First and Last Digit in a Number with an example. This C++ program allows the user to enter any numeric value, and it finds the first and last digit, and swap them.
#include<iostream>
#include<cmath>
using namespace std;
int main()
{
int number, firstDigit, lastDigit, count, a, b, SwapNum;
cout << "\nPlease Enter Any Number to find First and Last Digit = ";
cin >> number;
count = log10(number);
firstDigit = number / pow(10, count);
lastDigit = number % 10;
a = firstDigit * (pow(10, count));
b = number % a;
number = b / 10;
SwapNum = lastDigit * (pow(10, count)) + (number * 10 + firstDigit);
cout << "\nThe First Digit in a Given Number = " <<firstDigit;
cout << "\nThe Last Digit in a Given Number = " << lastDigit;
cout << "\nAfter Swapping First and Last Digit = " << SwapNum;
return 0;
}
C++ Program to Swap First and Last Digit in a Number Example 2
#include<iostream>
#include<cmath>
using namespace std;
int main()
{
int number, firstDigit, lastDigit, count, SwapNum;
cout << "\nPlease Enter Any Number to find First and Last Digit = ";
cin >> number;
count = log10(number);
firstDigit = number / pow(10, count);
lastDigit = number % 10;
SwapNum = lastDigit;
SwapNum = SwapNum * (round(pow(10, count)));
SwapNum = SwapNum + number % (int)(round(pow(10, count)));
SwapNum = SwapNum - lastDigit;
SwapNum = SwapNum + firstDigit;
cout << "\nThe First Digit in a Given Number = " <<firstDigit;
cout << "\nThe Last Digit in a Given Number = " << lastDigit;
cout << "\nAfter Swapping First and Last Digit = " << SwapNum;
return 0;
}
