如何显示已赋予多个值的变量的最大值? (C编程)

我正在为我的C编程班做一个家庭作业,所以我不是在寻找直接的答案,而是寻求指导或指导。我的代码非常简单,我们现在只使用C 3周,所以我提前道歉。到目前为止,我们只覆盖了条件,循环,计数器,多个选择的切换/中断/继续,逻辑运算符和读取字符,所以如果你提到的不是这个,我可能会毫无头绪。

10 int main(void)
11 {
12
13     /*Define variables*/
14     int response, btaxrate, taxrate;
15     float income,taxamount, netincome;
16
17
18     /* Start the dowhile loop for running the program more than once if the user wants to */
19     do{
20
21
22     /*Grab the income amount from the user */
23     printf("Enter the annual income: ");
24     scanf("%f", &income);
25     /* Check to make sure it is above 0 with a while loop */
26     while(income <= 0)
27         {
28             printf("Invalid income, enter the income again: ");
29             scanf("%f", &income);
30         }
31
32     /* Grab the base taxrate from the user */
33     printf("Enter the base tax rate: ");
34     scanf("%d", &btaxrate);
35     /* Check to make sure it is <10 or >30 with a while loop */
36     while(btaxrate < 10 || btaxrate > 30)
37         {
38             printf("Invalid base tax rate, enter the tax rate again: ");
39             scanf("%d", &btaxrate);
40         }
41
42     /* Determine what the taxrate is based on the income amount */
43     if(income >= 0 && income < 50000)
        {
45             taxrate=btaxrate;
46         }
47     if(income >= 50000 && income < 100000)
48         {
49             taxrate=btaxrate+10;
50         }
51     if(income >= 100000 && income < 250000)
52         {
53             taxrate=btaxrate+20;
54         }
55     if(income >= 250000 && income < 500000)
56         {
57             taxrate=btaxrate+25;
58         }
59     if (income >= 500000)
60         {
61             taxrate=btaxrate+30;
62         }
63
64
65     /* Equations for taxamount and netincome */
66     taxamount=(float)(income*taxrate)/(float)100;
67     netincome=(float)income-(float)taxamount;
68
69
70     /* Tell them their tax rate, how much they pay in taxes, and their net income after taxes*/
71     printf("Your tax rate is: %d%%", taxrate);
72     printf("\nYou pay $%.2f in taxes.", taxamount);
73     printf("\nAfter taxes your net income is: $%.2f", netincome);
74
75
76     /* Ask the user if they want to run the program again, get a value for yes if so */
77     printf("\nDo you want to continue? (0:Exit  1:Continue:)");
78     scanf("%d", &response);
79
80
81     } /* End do */
82
83     /* While part of dowhile to see if the program runs again */
84     while(response == 1);

我应该显示根据用户重新运行程序的次数确定的最高值,最低值和平均税额,然后打印它。因此,例如,如果他们运行5次(通过按1继续)并且taxamount的值为15000,8000,20000,35000和100000,我将如何打印“100000是最高的,8000是最低的,而平均值是35600“?

答案 0 :(得分:3)

您可以创建一个临时变量,在第一次迭代中保存taxamount的值,并在连续迭代中检查新值是否更大并相应地更新它。

从那里我想你可以猜测如何进行其余的计算。
