Question

我刚开始编程，我不知道自己在做什么。我的教授给了我们程序集，我已经完成了，但是当我编译文件时，我得到了

“J：\ Untitled1.cpp在函数`int main（）'中：

“36 J：\ Untitled1.cpp期望在'＆lt;＆lt;'之前的primary-expression令牌“

这是全套，现在记住我是初学者：

/** CONCEPTS PROGRAM #1, TEMPLATE
PROGRAM Name: Yay.cpp
Program/assignment: 
Description: Finds total
Input(s): 
Output(s): 
suffering_with_c++
Date of completion 
*/
//included libraries
#include <iostream>
#include <iomanip>
#include <stdlib.h>
#include <time.h.>

#define cls system("cls")
#define pauseOutput system("pause")//

using namespace std;
int main() 
{
    //variable declaration/initialization
    time_t nowIsTheMoment;
    time(&nowIsTheMoment); 
    string dateTime;//

    cls;
    cout <<"\new live in the moment--only this moment is ours. The Current Date and time is: "
    <<ctime (&nowIsTheMoment); << endl;//
    cout << "\nMy name is Moe Joe." <<endl;//
    cout << endl << "I think Computer Programming with C++ will be a bit more PHUN now!" 
         << endl;
    dateTime = ctime(&nowIsTheMoment);//
    cout << endl << "\nYo ho! I am here now...\n" << endl;
    cout << endl << "The Current Date and time is: "
     <<dateTime <<endl;//
    cout << "\nI know clearly that, if I DO NOT comment my programs/project work thorougly, I will lose substantial points.\n" ;

    cout << "\bHere is Pause Output in action....\n" << endl;//
    pauseOutput; //
    cls;//
    return 0; 
}

Answer 1

删除第36行的分号

<<ctime (&nowIsTheMoment); << endl;
                         ^
                         |

Answer 2

您忘记了#include <string>并使用string限定cout和std::。

Answer 3

首先删除.后<time.h>应该有所帮助。然后你得到了这个

ctime（＆amp; nowIsTheMoment）; ＆LT;＆LT; ENDL;

无法编译，因为<<需要左操作数（即：删除分号）。

我不是故意粗鲁，但在StackOverflow上提问之前你应该稍微努力一下......

我如何纠正“...之前的预期初级表达？”
