Question

在我的C类简介中进行工资单分配，目标是读取文本文件，然后将其工资信息输出到文本文件。我收到了一些不兼容的指针错误，CodeBlocks只给了我一个包含一堆乱码的输出文件。我发布了下面的文本文件和我的评论，这样你就可以理解我对我的代码做了些什么。任何帮助都会做，欣赏它们和gals。

2 (this is the number of employees)
5.50 (pay rate for employee 0)
10.00 (pay rate of employee 1)
3 (number of weeks)
2 (data in relation to this week)
1 10 30 13 30 (reads: employee 1 clocked in at 1030, clocked out 1330)
0 7 0 16 30   (reads: employee 0 clocked in at 700, clocked out  1630)
4
0 9 0 14 30

    }

    fclose(ofp);

}

这就是输出的样子。

Number of employees: 2
Number of weeks: 3
Wk 1
EmpID Hours Pay
 0 9.50 52.25
 1 3.00 30.00
Wk 2
EmpID Hours Pay
 0 5.50 30.25
 1 45.00 450.00
Wk 3
EmpID Hours Pay
 0 7.00 38.5.00
 1 4.00 40.00
Total
EmpID Hours Pay
 0 22.00 121.00
 1 52.00 520.00

这是我在payroll.o文件中得到的内容

Answer 1

在printLog中，最后一个参数的类型应为double，而不是int。
