小编Chi*_*uri的帖子

I was recently asked this question in a programming test. I can't seem to understand why I am getting the answer '1'. I am a beginner in the C programming language.

Here is my code:

#include<stdio.h>
int main()
{
    float c = 0;
    int n, i = 1;
    printf("Enter the number here: ");
    n = getchar();
    while (i <= 2*n - 1)
    {
        c = c + (1/i);
        i = i + 2;
    }
    printf("%f", c);
}

I have already …

我已经使用 browserify 来捆绑我的 js 文件。我收到表格错误

Uncaught TypeError: util.TextEncoder is not a constructor
    at Object.1.util (bundle.js:3)
    at o (bundle.js:1)
    at r (bundle.js:1)
    at bundle.js:1

这是我的bundle.js 的最初几行

(function(){function r(e,n,t){function o(i,f){if(!n[i]){if(!e[i]){var c="function"==typeof require&&require;if(!f&&c)return c(i,!0);if(u)return u(i,!0);var a=new Error("Cannot find module '"+i+"'");throw a.code="MODULE_NOT_FOUND",a}var p=n[i]={exports:{}};e[i][0].call(p.exports,function(r){var n=e[i][1][r];return o(n||r)},p,p.exports,r,e,n,t)}return n[i].exports}for(var u="function"==typeof require&&require,i=0;i<t.length;i++)o(t[i]);return o}return r})()({1:[function(require,module,exports){
var util = require('util');
var utf8 = new util.TextEncoder();

let secretDataTxt=document.querySelector(`#SecretData`);
let passwordTxt=document.querySelector(`#Password`);
let result=document.querySelector(`#Result`);

let encryptBtn=document.querySelector(`#encrypt`);

有人可以帮我解决这个错误吗？

编辑：这是一个工作示例

const util = require('util');
const utf8 = new util.TextEncoder();

console.log(utf8.encode("Hello"));

输出：Uint8Array(5) [ 72, 101, 108, …

有人可以解释为什么代码打印 "HelloWorld" 而不是 "HelloWorldThere" 吗？另外，为什么它会打印任何内容，因为 if 或 switch 语句中没有条件？这是代码：

#include <stdio.h>

int main()
{
    int a, b;

    if(printf("Hello"))
        switch(printf("World"))
            while(printf("There"))
            {
                return 0;
            }
}
