In this section, we are going to see how to reverse a number using various methods like while loop, recursion, for loop and do while loop with the help of examples. Example 1: Find Reverse Number in C++ Using While Loop Before moving to the program, let’s first understand how while l...
Inside the loop, the reversed number is computed using: reverse = reverse * 10 + remainder; Let us see how the while loop works when n = 2345. nn != 0remainderreverse 2345 true 5 0 * 10 + 5 = 5 234 true 4 5 * 10 + 4 = 54 23 true 3 54 * 10 + 3 = 543 2 true 2 54...

同样,shell能够区分开内部for循环和外部while循环各自的do和done命令。 如果真的想挑战脑力,可以混用until和while循环。 1$cattest162#!/bin/bash3# usinguntilandwhileloops4var1=35until[ $var1 -eq0]6do7echo"Outer loop: $var1"8var2=19while[ $var2 -lt5]10do11var3=$(echo"scale=4; $var1 ...

Let's see a simple C# example to reverse a given number. using System; public class ReverseExample { public static void Main(string[] args) { int n, reverse=0, rem; Console.Write("Enter a number: "); n= int.Parse(Console.ReadLine()); while(n!=0) { rem=n%10; reverse=reverse*...
So next, let’s translate this idea into Kotlin code using the division operator ‘/‘ and the modulus operator ‘%‘: fun reverseNumber(number: Int): Int { var n = number var result = 0 while (n > 0) { result = 10 * result + n % 10 n = n / 10 } return result } Next...
Explanation: In the exercise above the code defines a function named "string_reverse()" that takes a string as input and returns its reversed version using a while loop and string manipulation. The final print statement demonstrates the result of calling the "string_reverse()" function with the...
bash shell提供了for命令,允许你创建一个遍历一系列值的循环。每次迭代都使用其中一个值来执行已定义好的一组命令。下面是bash shell中for命令的基本格式。 1forvarinlist2do3commands4done 在list参数中,你需要提供迭代中要用到的一系列值。可以通过几种不同的方法指定列表中的值。
