下面代码中，bankaccount *account和bankaccount account的区别是什么？ #include <stdio.h> typedef struct { double balance; } bankaccount; //开户 void openaccount(bankaccount *account) { account->balance = 0; printf("开户成功"); } void deposit(bankaccount *account, double amount) { account->balance += amount; printf("存款 %.2f 成功", amount); } void withdraw(bankaccount *account, double amount) { if (account->balance >= amount) { account->balance -= amount; printf("取款 %.2f 成功", amount); } else { printf("取款 %.2f，余额不足失败", a
`bankaccount *account` 是一个指向 `bankaccount` 结构体类型的指针，通过这个指针可以操作结构体对象所指向的内存空间。 `bankaccount account` 则是直接定义了一个 `bankaccount` 结构体类型的变量。 在您给出的代码示例中，函数 `openaccount`、`deposit` 和 `withdraw` 都使用了 `bankaccount *account` 这种指针形式，这样做的好处是可以避免在函数调用时对结构体进行值传递带来的大量数据复制，提高程序的性能，并且可以在函数内部直接修改调用者传入的结构体对象的内容。 如果使用 `bankaccount account` 的形式作为函数参数进行值传递，函数内部对其的修改不会反映到函数外部调用处的原始结构体对象上。 [2024-08-08 15:43:13 | AI写代码神器 | 174点数解答]
