我正在编写一个程序,该程序从2个列表中获取最高/最低值并将其记录下来,以及它们出现在哪个循环增量处。
这是导致问题的我的代码部分。您在此处看到的所有变量都已提前声明:
for(int i = 0; i < days; i++){
highest_temp = high_temp[i];
lowest_temp = low_temp[i];
while (high_temp[i] > highest_temp){
highest_temp = high_temp[i];
highest_temp_day = i+1;
}
while (low_temp[i] < lowest_temp){
lowest_temp = low_temp[i];
lowest_temp_day = i+1;
}
}
printf("\n\nThe highest temperature was %d, on day %d", highest_temp, highest_temp_day);
printf("\nThe lowest temperature was %d on day %d", lowest_temp, lowest_temp_day);
这是我的输出:
The highest temperature was 9, on day 0
The lowest temperature was -4 on day 0
highest_temp_day
和lowest_temp_day
变量都被初始化为0,但在while循环中没有更新。
您的代码需要重组:
// these need to be outside so they don't get redefined constantly
int highest_temp = high_temp[0];
int lowest_temp = low_temp[0];
// initialize these to the first day
int highest_temp_day = 0;
int lowest_temp_day = 0;
// iterate through the array
for (int i = 0; i < days; i++) {
// change whiles to ifs
if (high_temp[i] > highest_temp) {
// update vars
highest_temp = high_temp[i];
highest_temp_day = i + 1;
}
if (low_temp[i] < lowest_temp) {
lowest_temp = low_temp[i];
lowest_temp_day = i + 1;
}
}
printf("\n\nThe highest temperature was %d, on day %d", highest_temp, highest_temp_day);
printf("\nThe lowest temperature was %d on day %d", lowest_temp, lowest_temp_day);
