Question

请帮我找到最高和最低温度。我想我错过了让它有效的东西。差不多完成了。我是否需要使用if创建条件？请帮我找到最高和最低温度。我想我错过了让它有效的东西。差不多完成了。我是否需要使用if来创建条件？

#include <stdio.h>
#define NUMS 3

int main(void) {

int high;
int low;
int totalhigh=0;
int totallow=0;
double average;
int i;
printf("---=== Temperature Analyzer ===---\n");
for (i = 0; i < 3; i++)
{
printf("Enter the high temperature for the day %d: ", i + 1);
scanf("%d", &high);
printf("Enter the low temperature for the day %d: ", i + 1);
scanf("%d", &low);
totalhigh = high + totalhigh;
totallow = low + totallow;
    }

average = (double)(totalhigh + totallow) / 6 ;
printf("The average (mean) temperature was: %.2lf\n", average);
return 0;
}

Answer 1

与我输入时收到的评论没有什么不同。

#include <stdio.h>
#define NUMS 3

int main(void) {

    int high;
    int low;
    int highest =-42;
    int highday = -1;
    int lowday  = -1;
    int lowest  = 42;
    int totalhigh=0;
    int totallow=0;
    double average;
    int i;

    printf("---=== IPC Temperature Analyzer ===---\n");
    for (i = 0; i < 3; i++)
    {
        printf("Enter the high value for day %d: ", i + 1);
        scanf("%d", &high);
        printf("Enter the low  value for day %d: ", i + 1);
        scanf("%d", &low);
        printf("\n");

        totalhigh = high + totalhigh;
        totallow = low + totallow;
        if (high>highest)
        {    highest=high;
             highday=i+1;
        }
        if (low<lowest)
        {   lowest=low;
            lowday=i+1;
        }
    }

    average = (double)(totalhigh + totallow) / 6 ;

    printf("The average (mean) temperature was:  %.2lf\n", average);
    printf("The lowest         temperature was: %3d on day %d\n", lowest, lowday);
    printf("The highest        temperature was: %3d on day %d\n", highest, highday);
    return 0;
}

Answer 2

您需要记录最高（以及最低）。

struct hit
{
    int value,
        day;
};
struct hit highest = {-40; 0}, lowest = {+40; 0};
....
if (high > highest.value)
{
    highest.value = high;
    highest.day = i;
}
...

最后，您可以打印已创建的值：

print("The highest has been %d on day %d\n", highest.value, highest.day);
