c中3d数组的和值

Question

基于test.h文件,该函数应输出1.000作为平均值,但我得到错误的值输出数组的每个位置保持的值为1.0,并且4*5*10 = 200是总位置

#include <stdio.h>
#include "test.h"

float avgLeaguePlayer(float leagueTeams[4][5][10]);

int main()
{
        while (1)
        {
                printf("MENU\n");
                printf("=====\n");
                printf("  1. Entire League Average Player Rating\n");
                printf("  2. Second Function\n");
                printf("  3. Third Function\n");
                printf("  4. Exit\n");
                printf("Enter selection : ");

                int sel;
                float averagePlayer;
                scanf("%d", &sel);
                switch (sel)
                {
                case 1:
                        averagePlayer = avgLeaguePlayer(leagueTeams);
                        printf("Average Player Rating: %f\n", averagePlayer);
                        break;
                case 2:
                        printf("2\n");
                        // call function 2;
                        break;
                case 3:
                        printf("3\n");
                        // call function 3;
                        break;
                case 4:
                        break;
                default:
                        printf("Invalid Input\n");
                }
                break;
        }
}

float avgLeaguePlayer(float leagueTeams[4][5][10])
{
        int layerOne = 0;
        int layerTwo = 0;
        int layerThree = 0;
        float sum = 0.0;
        float avg = 0.0;

        for (layerOne = 0; layerOne < 4; layerOne++)
        {
                for (layerTwo = 0; layerTwo < 5; layerTwo++)
                {
                        for (layerThree; layerThree < 10; layerThree++)
                        {
                                sum += leagueTeams[layerOne][layerTwo][layerThree];
                        }
                }
        }
        avg = (sum / 200);
        return avg;
}

我需要帮助格式化代码以获得正确的输出.我是c的新手,谢谢

这里有一个问题

for(layerThree; layerThree<10; layerThree++)

这是第一次迭代这个嵌套循环时很好,因为它被layerThree初始化0为定义时.但是对于后续迭代,layerThree不会重置为0.事实上10,循环永远不会再次迭代.所以内循环应该是

for(layerThree = 0; layerThree < 10; layerThree++)
