For example: If input number is 12345 Then reversed number will be 54321 To make a program like that we need to access every digit individually of entered number from last Modulus operator provides such condition so first we take modulus of number until it become zero and add the every single digit which produce by modulus operator into our new integer variable which is named as reverse in the program with at each iteration of for loop When for loop is break variable revers will have the reverse of entered number #include<iostream> using namespace std; int main() { int number, reverse = 0; cout<<"Input a Number to Reverse and press Enter: "; cin>> number; // Taking Input Number in variable number for( ; number!= 0 ; ) { reverse = reverse * 10; reverse = reverse + number%10; number = number/10; } cout<<"New Reversed Number is: "<<reverse; return 0; }
