Question

所以我应该从文档中做一行矩阵，但是编译器会继续打印错误的答案。更不用说在用另一个元素替换一个元素时，程序不会对命令做出反应。

#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>

const char FV[] = "Masyvas.txt";
using namespace std;
int main()
{
    int A[10];
    int i,j, m, n;
    ifstream Mas(FV);
    cout << "Parasykite masyvo elemento indekso numeri, pries kuri iterpsite nauja elementa - ";
    cin >> n;
    cout << "irasykite iterpiamo elemento reiksme - ";
    cin >> m;
    for (i = 0; i < 5; i++)
    {
        Mas >> A[i];
    }
    for ( j = n; j < 5; j++)
    {
        A[j + 1] = A[j];
        A[n] = m;
    }
    for (i = 0; i < 5; i)
    {
        cout << " " << A[i] << endl;
    }
    Mas.close();
    return 0;
}

问题出在这一行：

for (i = 0; i < 5; i++)

这里有无限循环，因为条件<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Domene informasjon</title>  <link href="css/bootstrap.min.css" rel="stylesheet" />  <script src="jquery/jquery-2.1.4.min.js" type="text/javascript"></script> <script src="js/bootstrap.min.js" type="text/javascript"></script> <script src="js/bootstrap.js" type="text/javascript"></script> </head> <body> <div class="container-fluid"> <div class="row"> <div class="col-xs-12"> <div class="table-responsive"> <?php if(!isset($_GET['field'])) $field = 'ID'; else $field = $_GET['field']; if(!isset($_GET['sorting'])) $sort = 'ASC'; else $sort = $_GET['sorting']; $sql = "SELECT * FROM server1 ORDER BY " .$field."

很容易找到你的身边！下次使用任何调试器来分析这么简单的问题。

所以，只需用这一行替换该行来修复它：
