下面代码中的bankaccount *account，account->balance += amount;具体解释原理和作用 #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
在这段 C 语言代码中： `bankaccount *account` 定义了一个指向 `bankaccount` 结构体类型的指针 `account` 。 `account->balance += amount;` 这行代码的作用是将传入的金额 `amount` 累加到由 `account` 指针所指向的结构体对象的 `balance` 成员中。 原理是通过指针操作来直接修改指针所指向的结构体对象中的成员值。由于 `account` 是一个指向 `bankaccount` 结构体的指针，使用 `->` 运算符可以访问和操作指针所指向结构体对象的成员。在这种情况下，就是将 `amount` 的值加到 `balance` 成员上，实现了存款操作中余额的增加。 [2024-08-08 15:18:14 | AI写代码神器 | 161点数解答]
