Unable to call matrix matrix from main function in c++? [duplicate]

Don't know how to declare matrix using pointers and passing into the function and also not getting any useful resource from internet.

void wavePrint (int* arr[],int m)
{

    for (int i = 0; i < m; ++i){

        if(i%2==0) for(int j = 0; j < m; ++j)cout<<*(arr[j])<<" ";
        
        else for (int j = m-1; j >= 0; --j)cout<<*(arr[j])<<" ";
    }
}    

int main(int argc, char const *argv[])
{

    int* arr[5]={
        {1, 2, 3, 4, 5},
        {6, 7, 8, 9, 10},
        {11, 12, 13, 14, 15 },
        {16, 17, 18, 19, 20 },
        {21, 22, 23, 24, 25 }
    };

    wavePrint(*arr,5);
}
