如果循环，则为2的幂 [英] Power of 2 if loop

问题描述

尝试这样做：

使用FOR循环，从1到50显示2的幂。   （2到1的功率到2到50的功率）。使用长变量来存储结果。示例：2到4的幂是2 x 2 x 2 x 2. 

Using a FOR loop, display the powers of 2 from 1 to 50.   (2 to the 1st power through 2 to the 50th power). Use a long variable to store your results. Example: 2 to the 4th power is 2 x 2 x 2 x 2. 

我见过有人使用Math.pow （）但我不知道如何插入这里，因为我没有要求用户提供任何输入。 

I've seen people using the Math.pow() but I don't know how it would work being plugged in here as I'm not asking a user to provide any input. 

仅供参考我这是我编程的第二周所以请保持简单。请

FYI this is my second week in programming so keep it simple, please. 

推荐答案

将长整数设置为1 。

Set a long integer to 1.

写一个执行50次的'for'循环。每次循环，将你的整数乘以2并显示结果。

Write a 'for' loop that executes 50 times. Each time through the loop, multiply your integer by 2 and display the result.

我们不应该在这个论坛上做家庭作业，所以这和我能告诉你的一样多。如果你遇到困难，我们可以（可能）帮助你解决代码中的特定问题。

We are not supposed to do homework assignments on this forum, so that's about as much as I can tell you. Have a go, and if you get stuck we can (might) help with specific problems in your code.
