Reverse Number code example

Example 1: reverse number in java

public class ReverseNumber {
    public static void main(String[] args) {
        int num = 1234, reversed = 0;

        while(num != 0) {
            int digit = num % 10;
            reversed = reversed * 10 + digit;
            num = num / 10;
        }
        System.out.println("Reversed Number: " + reversed);
}}

Example 2: reverse a number in c

#include <stdio.h>
int main() {
    int n, rev = 0, remainder;
    printf("Enter an integer: ");
    scanf("%d", &n);
    while (n != 0) {
        remainder = n % 10;
        rev = rev * 10 + remainder;
        n /= 10;
    }
    printf("Reversed number = %d", rev);
    return 0;
}

Example 3: php random number

// $min and $max are optional
rand($min,$max);

Example 4: program to reverse a number in c

#include <stdio.h>
int main() {
    int n, rev = 0, remainder;
    printf("Enter an integer: ");
    scanf("%d", &n);
    while (n != 0) {
        remainder = n % 10;
        rev = rev * 10 + remainder;
        n /= 10;
    }
    printf("Reversed number = %d", rev);
    return 0;
}

Example 5: print reverse number

void printReverse(int n) {
  if (n < 1) return;
  cout << n << endl;
  printReverse(n - 1);
}

printReverse(10);  /// 10 9 8 7 6 5 4 3 2 1
