在c中找到三维数组中的最大元素

Question

我的任务是从一个三维数组中输出最高温度值。不幸的是，程序总是输出 9.6，它对应于索引 0 0 0。

`

#include <stdio.h>
  
double max_temperature_week(double temperature[52][7][24]){
    int i,j,k;
    double max = temperature[0][0][0];
  
    for(i = 0; i < 52; i++){
        for(j = 0; j < 7; j++){
            for(k = 0; k < 24; k++){
                if(temperature[i][j][k] > max){
                    temperature[i][j][k] = max;
                    
                }
            }
        }
        
    }
  
    return max;
}
  
int main()
{
    int i,j,k;
    double temperature[52][7][24] = {{

            {9.6,  9.4, 9.3, 9.1, 7.9, 7.7, 7.3, 7.2, 8.8, 9.3, 9.7, 9.4, 10.2, 9.7, 9.9, 9.5, 9.2, 9.3, 9.2, 7.1, 6.1, 5.9, 5.6, 5.2},
            {4.9, 4.6, 4.6, 4.1, 3.5, 3.1, 2.6, 2.6, 3.5, 5.1, 6.2, 8.3, 9.0, 9.3, 9.1, 8.0, 6.8, 6.4, 5.4, 5.2, 4.8, 4.5, 5.0, 5.5},
            {6.3, 6.8, 7.0, 7.2, 7.1, 7.2, 7.1, 7.4, 7.7, 8.2, 8.7, 9.1, 8.8, 8.7, 8.6, 8.4, 8.0, 7.9, 7.7, 7.6, 7.5, 7.3, 7.3, 7.2},
            {7.1, 7.0, 6.9, 6.8, 6.7, 6.7, 6.7, 6.6, 6.7, 6.8, 6.9, 7.2, 7.5, 7.7, 8.1, 8.3, 8.0, 7.7, 8.1, 8.2, 7.7, 7.5, 7.7, 7.9},
            {8.1, 8.0, 7.9, 7.8, 7.5, 7.2, 6.9, 7.2, 8.0, 8.4, 8.7, 9.0, 8.7, 8.9, 9.0, 7.8, 8.5, 8.1, 7.7, 7.7, 6.7, 7.0, 6.5, 7.1},
            {6.4, 6.6, 6.3, 5.8, 5.0, 4.9, 4.7, 4.6, 4.9, 5.3, 6.1, 5.5, 5.3, 5.7, 5.8, 6.5, 6.6, 5.8, 5.8, 7.1, 7.0, 7.0, 6.3, 5.8},
            {4.4, 4.0, 3.8, 3.8, 4.2, 4.2, 4.3, 3.8, 4.4, 5.2, 5.7, 5.9, 6.1, 6.7, 6.3, 5.9, 5.5, 5.1, 5.0, 5.0, 5.2, 5.7, 7.2, 7.7}

                               }}; 
    printf("Largest in given array is %lf", max_temperature_week(temperature));
    return 0;
}

Answer 1

您将第一个值分配给值大于最大值的数组的所有元素。

它一定要是：

max = temperature[i][j][k];
