函数不应该在C＆＃x2B;＆＃x2b;

我正在尝试制作自己的功能，该功能采用双阵列并返回最大索引。但是，当我运行代码以在下面的随机数组中检查函数时，它应该返回9时返回0。在main（）中使用的代码有什么问题，但在函数中使用时不使用？

int findMaxIndex(double array[]) {
    int maxIndex=0;
    int arraySize = sizeof(array)/sizeof(array[0]);
    for (int i=0;i<arraySize;i++) {
        if (array[maxIndex]<array[i]) {
            maxIndex=i;
        }
    }
    return maxIndex;
}

int main() {
    double array[10] = 
{11.20,22.2,33.3,43.4,55.5,66.6,77.7,88.8,90.0,100};

    cout <<findMaxIndex(array)<<endl;

    return 0;
}

I am trying to make my own function that takes a double array and returns maximum index. But when I run the code to check the function with a random array below, it returns 0 when it's supposed to return 9. When I run the same exact code inside the function in main, it works. What's wrong with my code that is working in main() but not when used inside a function?

int findMaxIndex(double array[]) {
    int maxIndex=0;
    int arraySize = sizeof(array)/sizeof(array[0]);
    for (int i=0;i<arraySize;i++) {
        if (array[maxIndex]<array[i]) {
            maxIndex=i;
        }
    }
    return maxIndex;
}

int main() {
    double array[10] = 
{11.20,22.2,33.3,43.4,55.5,66.6,77.7,88.8,90.0,100};

    cout <<findMaxIndex(array)<<endl;

    return 0;
}
