Question

我的教授说我的代码缺少这两个方面

必须使用默认值开头-2的init变量
您的程序缺少变量分配语句-3

但是我不确定它们的含义。

我已将int变量设置为默认值0，但我不知道如何为它们分配新值。

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

 using namespace std;

 int main ()
 {
    string theatre = "AMC Universal CityWalk";
    string present = "Presenting";
    string movie = "A Star is Born Encore";
    string show = "Show time";
    string time = "PM";
    string day = "Date";
    string room = "Theatre";
    string rating = "PG-13";
    string admission = "Adult Admission";
    string ad = "Don't forget to get your free small popcorn"
        " with 4 tickets or more!!!";
  /*
    int timeHour = 3;
    int timeMinute = 20;
    int dateMonth = 04;
    int dateDay = 12;
    int dateYear = 2019;
    int roomNumber = 10;
    float price = 12.75;
  */
    int timeHour = 0;

    int timeMinute = 0;
    int dateMonth = 0;
    int dateDay = 0;
    int dateYear = 0;
    int roomNumber = 0;
    float price = 0.0;

    cout << "\t\t" << theatre << endl;
    cout << "\t\t\t" << present << endl;
    cout << "\t\t" << movie << endl;
    cout << show << ": " << timeHour << ":" << timeMinute << " " << time;
    cout << "\t" << day << ": " << dateMonth << "/" << dateDay <<     "/" <<
        + dateYear << endl;
    cout << room << ": " << roomNumber;
    cout << "\t\t\t" << rating << endl;
    cout << admission << ": $" << price << endl;
    cout << ad << endl;


}

我需要打印出注释部分中的值，但是我无法弄清楚如何为int变量分配新值。

首先阅读此https://en.wikipedia.org/wiki/Assignment_(computer_science) 如果要为变量设置新值，请执行以下操作：

int timeHour = 0;
timeHour = 10;
