Term 2了。。。開始學web development了。。有問題會問

就float pay；
double我沒學過。。。是怎樣的command？
然后可以if（choice=='Y','y')這樣用嗎？

double 類型沒學過也太牽強些了吧?
把 choice 轉換成小寫或大寫字母比對就可解決

完了。。。
今天去show demo給lecturer看
他說我的program還不夠convenient for the user
要我改更convenient的。。。
我想到頭快爆炸了
請高人指點我好嗎

1. #include<iostream>
   
2. using namespace std;
   
3. 
   
4. int main()
   
5. {
   
6. int a,b,c,d,i,j,k,l;
   
7. double pay;
   
8. cout<<"Please enter the number of managers\n";
   
9. cin>>a;
   
10. cout<<"Please enter the number of hourly workers\n";
    
11. cin>>b;
    
12. cout<<"Please enter the number of commission workers\n";
    
13. cin>>c;
    
14. cout<<"Please enter the number of piece workers\n";
    
15. cin>>d;
    
16. 
    
17. if(a>0)
    
18. {
    
19. cout<<"Please enter the 1st manager weekly salary\n";
    
20. cin>>i;
    
21. cout<<"The 1st manager weekly salary is [        DISCUZ_CODE_0        ]quot;<<i<<"\n";
    
22. }
    
23. if(a=0)
    
24. {
    
25. cout<<"There were no managers working in this week\n";
    
26. }

复制代码

我的想法是在頭直接input每個position有多少個employee
然后下面再慢慢input
假設我的a是5
我要如何讓這個出現？（例子）

cout<<"Please enter the 1st manager weekly salary\n";
cin>>i;
cout<<"Please enter the 2nd manager weekly salary\n";
cin>>i;
cout<<"Please enter the 3rd manager weekly salary\n";
cin>>i;
cout<<"Please enter the 4th manager weekly salary\n";
cin>>i;
cout<<"Please enter the 5th manager weekly salary\n";
cin>>i;

cout<<"The 1st manager weekly salary is $"<<i<<"\n";
cout<<"The 2rd manager weekly salary is $"<<i<<"\n";
cout<<"The 3rd manager weekly salary is $"<<i<<"\n";
cout<<"The 4th manager weekly salary is $"<<i<<"\n";
cout<<"The 5th manager weekly salary is $"<<i<<"\n";

你都說了 a = 5, 那麼就把你的循環儲存在一個 Array 中

虚空使者

1. #include<iostream>
   
2. using namespace std;
   
3. 
   
4. int main()
   
5. {
   
6. int a,b,c,d,i,j,k,l,y[30],z
   
7. double pay;
   
8. cout<<"Please enter the number of managers\n";
   
9. cin>>a;
   
10. cout<<"Please enter the number of hourly workers\n";
    
11. cin>>b;
    
12. cout<<"Please enter the number of commission workers\n";
    
13. cin>>c;
    
14. cout<<"Please enter the number of piece workers\n";
    
15. cin>>d;
    
16. 
    
17. cout<<"Enter the weeklypay for all managers\n";
    
18. for(z=0;z<a;z++)
    
19. {
    
20. cin>>y[z];
    
21. }
    
22. cout<<"The salary for all the managers are\n";
    
23. for(z=0;z<a;z++)
    
24. cout<<"$"<<y[z]<<"\n";

复制代码

我這個array只能解決第1類型worker（manager)而已
至于我第2個worker有formula的
i=payrate
j=hoursworked
k=OT payrate（only applicable if hoursworked exceed 40 hours)
l=OT hours worked(only applicable if hoursworked exceed 40 hours, eg work for 50 hours it must automatically count 10 hours as OT hours)
pay = i*j+(1.5*k*l)
我就真的不知道要怎樣做了

#include
using namespace std;

int main()
{
int a,b,c,d,i,j,k,l,y[30],z
double pay;
couta;
coutb;
coutc;
coutd;

cout

方法都一樣, 做好所要的計算然後儲存在 Array 中
先後輸入次序就看你自己怎麼設計了

虚空使者

可以請大大示范第2個worker的code給我看嗎？
我對cin那4個int那里非常混亂
既然只能cin>>y[z]這一種
那我要怎樣把i，j，k，l這4個int放下去？
關于array的東西我們老師并沒有解釋到很深
我也懂得不是很多

你應該去買本書學習基礎, 以下是個簡單的例子自己研究吧

1. 
   
2. #include<iostream>
   
3. using namespace std;
   
4. 
   
5. int main()
   
6. {
   
7.         int iNumber = 0, iMin = 0, i;
   
8.         long lTotal = 0;
   
9.         double dAverage = 0;
   
10. 
    
11.         cout << "Please enter the number of student : ";
    
12.         cin >> iNumber;
    
13.         cout << "Please enter minimum score : ";
    
14.         cin >> iMin;
    
15. 
    
16.         int *iScore = new int[iNumber];
    
17.         for(i=0; i<iNumber; i++)
    
18.         {
    
19.                 cout << "Enter student" << i+1 << " test score : ";
    
20.                 cin >> iScore[i];
    
21.                 lTotal += iScore[i];
    
22.         }
    
23. 
    
24.         cout << "\n\nResults : \n";
    
25.         for(i=0; i<iNumber; i++)
    
26.                 if(iScore[i] < iMin)
    
27.                         cout << "Student" << i+1 << " need " << iMin - iScore[i] << " marks to reach the goal.\n";
    
28. 
    
29.         dAverage = lTotal / iNumber;
    
30.         cout << "\nThis class average score is : " << dAverage << "\n";
    
31.         system("pause");
    
32. 
    
33.         delete[] iScore;
    
34.         return 1;
    
35. }

過了第2個了
但是一直搞不懂第3個worker哪里寫錯
一直出同一個的output給我。。。

出來的是這個。。
可以請大大告訴我哪個地方有問題嗎？
我認為是最后幾段有點問題。。。
我想解決這個了這個第4個worker我就沒問題了

{
cout<<"Enter the weekly sales for commission worker "<<z+1<<"\n";

看清楚紅色部份同以下有甚麼分別嗎?

int a = 0;
for(int i=0; i<10; i++)
{
      a = i;
}

for(int i=0; i<10; i++)
{
     cout << a << "\n";
}
