如何向用户询问0到255之间的三个整数，因为无符号字符的范围可以是0到622537 [英] How to ask the user to inter three integers from 0 to 255, since unsigned character can range from 0 to 622537

问题描述

我们如何在c中编程输入0到255之间的整数，因为无符号字符的范围是0到622537



我尝试过：



如何在c中编程输入0到255之间的整数，因为无符号字符的范围是0到622537

how can we program in c to enter integer from 0 to 255 , since unsigned character can range from 0 to 622537

What I have tried:

how can we program in c to enter integer from 0 to 255 , since unsigned character can range from 0 to 622537

推荐答案

如果存储大小为1byte，则无符号字符范围为0-255。您的问题有点不清楚。

Unsigned char range is 0-255 , if it is 1byte of storage size. Your questions is bit unclear.

首先，16位无符号字符的范围是0到65535.

使用户输入范围为0的整数255与char的范围无关。

问题表明你对C编程知之甚少。



学习C是一个漫长的过程，不要跳过步骤，暂时忘记你的项目，并真正学习C语言。

通过制作自己的项目来学习C就像通过赢得一级方程式锦标赛来学习开车一样，它不起作用。

First of all the range of a 16bits unsigned char is 0 to 65535.
Making the user enter an integer of range 0 to 255 is not related to the range of a char.
The question show that you have little understanding of C programming.

Learning C is a long process, don't skip steps, forget your project for now, and learn C really.
Learning C by making your own project is like learning to drive a car by winning the Formula 1 championship, it don't work.
