c - C 数组中的最小值、最大值和位置

Question

我是 C 的新手，如果我的怀疑看起来很愚蠢但我被卡住了，请理解。我进行了很多搜索，但找不到解决我的问题的答案。

我的程序应该询问用户比赛的圈数，然后询问每圈花费的时间。

然后写出最快、最慢、单圈平均时间和比赛总时间。现在，总时间和平均值正在发挥作用。最小值和最大值及其位置不是。

这是我的代码:

#include<stdio.h>
#include<cs50.h>

int main()
{
int array[100], maximum, minimum, c, laps, location = 1;
float average;
int summation;

 printf("how many laps did the race had?\n");
 laps = GetInt();
 printf("how many time each of the %i laps took in seconds?\n", laps);

 for (c = 0; c < laps; c++)
 {
      scanf("%d", &array[c]);
      maximum = array[0];
      minimum = array[0];
 }
 for ( c = 1; c < laps; c++)
 {
      if (array[c] < minimum)
      {
          minimum = array[c];
          location = c + 1;
       }
       else if (array[c] > maximum)
       {
           maximum = array[c];
           location = c + 1;
       }
 for ( c = 0; c < laps; c++)
 {
      summation = summation + array[c];
      average = (summation / laps);
 }
 }

printf("The fastest lap was %d and had the time of %d seconds.\n", location, minimum);
printf("The slowest lap was %d and had the time of %d seconds.\n", location, maximum);
printf("The race took %d seconds\n", summation);
printf("The avegare time for lap was %.2f seconds.\n", average);

}

Answer 1

for ( c = 0; c < laps; c++)
 {
      summation = summation + array[c];
      average = (summation / laps);
 }

应该是

int summation = 0;
for ( c = 0; c < laps; c++)
 {
      summation = summation + array[c];
 }
 average = (summation / laps);

因为在知道总和之前计算平均值是没有用的

您对最小和最大位置使用相同的location。使用 minLocation 和 maxLocation 代替

你有一个括号问题:

for ( c = 1; c < laps; c++)
 {
      if (array[c] < minimum)
      {
          minimum = array[c];
          location = c + 1;
       }
       else if (array[c] > maximum)
       {
           maximum = array[c];
           location = c + 1;
       }
 for ( c = 0; c < laps; c++)
 {
      summation = summation + array[c];
      average = (summation / laps);
 }
 }

应该是

 for ( c = 1; c < laps; c++)
 {
      if (array[c] < minimum)
      {
          minimum = array[c];
          location = c + 1;
       }
       else if (array[c] > maximum)
       {
           maximum = array[c];
           location = c + 1;
       }
}
 for ( c = 0; c < laps; c++)
 {
      summation = summation + array[c];
      average = (summation / laps);
 }
