Visual Studio 2019：RangeChecks 检测代码检测到超出范围的数组访问。

Question

写了一个关于抽取学号的程序，如下：

    #include<iostream>
    #include<fstream>

    #include<cstring>
    #include<sstream>

    #include<iomanip>
    #include<algorithm>
    #include<cstdio>
    #include<ctime>
    #include<cstdlib>

    using namespace std;

    const string PASSWORD = "070714";
    int a, j, k, i, co = 0;
    int arr[55] = {};
    char m[200] = {};
    string in = "", n = "";

    void instructions() {
        cout << setw(60) << "使用说明";
        cout << "重启程序请输入“重启”，关闭程序请输入“退出”。" << endl;
        cout << "输入一个小于班级人数的数字，将输出一些随机数。" << endl;
        cout << "输入记事本模式以进入记事本模式，此时你可以输入文本，按Enter键确定。" << endl;
        cout << "输入打开记事本以查看记事本的内容。" << endl;
        cout << "\n\n\n还有彩蛋等你来试！\n\n\n";
        system("pause");
    }

    void show() {

Answer 1

main中的

        arr[55] = {};
        m[200] = {};

这两行去了
