新学生使用字符串和函数 [英] New student working with strings and functions

问题描述

我需要询问用户3个职位，然后创建一个程序，预测的工作，用户将有...像一个财富出纳员。此分配的说明是为输入的作业的摘要创建一个函数，然后显示算命师。我很困惑如何发送字符串日期到函数，然后再次调用它。我不断收到读取太多参数发送到函数的错误，以及在第89行之前<<<<>之前的预期主表达式

  using namespace std; 
 
 void splash（）; 
 void welcome（）; 
 void summary（string，string，string，string）;

 int num1; 
 
 splash（）; 
 welcome（）;

 unsigned seed = time（0）;

 getline（cin，career1）;

 cout<<< down12; 
 cout< ;<Enter Career 2：; 
 getline（cin，career2）; 
 system（CLS）; 
 
 cout< down12; 
 cout<< over3< Enter Career 3：; 
 getline（cin，career3）; 
 system（CLS）; 
 
 cout<< down10; 
 
 if（num1 == 1）
 summary（career1，career2，career3，career1）; 
 else if（num1 == 2）
 summary（career1，career2，career3，career2）; 
 else if（num1 == 3）
 summary（career1，career2，career3，career3）; 
 else 
 summary（career1，career2，career3，none of these jobs ...）; 
 
 cout<< down10; 
 return EXIT_SUCCESS; 
 
} 
 
 void summary（string，string，string，string）
 {
 cout< down5; 
 cout<< over3< 你输入的工作是：< endl; 
 cout<< over3< __________________________< endl; 
 cout<< over3< 1.< string<< endl; 
 cout<< over3< 2.< string<< endl; 
 cout<< over3< 3.< string<< endl; 
 cout<< over3< 你的工作将是< string<< endl; 
} 
  

解决方案

的函数定义如下：

  void summary（string string1，string string2，string string3，string string4）; 
  

此外，您还需要确保为输出使用适当的变量名。

希望有所帮助！

I need to ask the user for 3 job titles and then create a program that will "predict" the job the user will have...like a Fortune Teller. The instructions for this assignment was to create a function for the summary of the jobs entered and then display the fortune teller. I am confused as to how to send string date to the function and then call it again. I keep getting errors that read too many parameters sent to function and "expected primary-expression before << on line 89

    using namespace std;

void splash();
void welcome();
void summary(string,string,string,string);

int main(int argc, char *argv[]) 
{
    string career1, career2, career3;
    int num1;

    splash ();
    welcome ();

    system("CLS");

    unsigned seed = time(0);
    srand(seed);
    num1 = 1 +rand() % 4;   

    cout << down12;
    cout << over3 << "Enter Career 1: ";
    getline(cin, career1);
    system("CLS");

    cout << down12;
    cout << over3 << "Enter Career 2: ";
    getline(cin, career2);
    system("CLS");

    cout << down12;
    cout << over3 << "Enter Career 3: ";
    getline(cin, career3);
    system("CLS");

    cout << down10;

    if (num1 == 1)
        summary(career1,career2,career3,career1);
    else if (num1 == 2)
        summary(career1,career2,career3,career2);
    else if (num1 ==3)
        summary(career1,career2,career3,career3);
    else 
        summary(career1,career2,career3,"none of these jobs...");

    cout << down10;
    return EXIT_SUCCESS;

}

void summary(string,string,string,string)
{
    cout << down5;
    cout << over3 << "The jobs you entered were:" << endl;
    cout << over3 << "__________________________" << endl;
    cout << over3 << "1. " << string << endl;
    cout << over3 << "2. " << string << endl;
    cout << over3 << "3. " << string << endl;
    cout << over3 << "Your job will be " << string <<endl;  
}

解决方案

I would just adjust the parameters of the function definition like so:

void summary(string string1, string string2, string string3, string string4);

Also, you'll want to be sure that you're using the appropriate variable names for your output.

Hope that helps!
