I don't really understand how the pointer to pointer works. Any way to do the same work without using pointer to pointer?

    struct customer{
        char name[20];
        char surname[20];
        int code;
        float money;
    };
    typedef struct customer customer;
    void inserts(customer **tmp) 
    {
    *tmp = (customer*)malloc(sizeof(customer));
    puts("Give me a customer name, surname code and money");
    scanf("%s %s %d %f", (*tmp)->name, (*tmp)->surname, &(*tmp)->code,&(*tmp)->money);
    }
