int函数返回ASCII特殊字符?

好的,在看了@Pablo评论的类似问题后,它现在起作用了。 答案中有以下代码:

void getNumbers(struct Numbers *numbers) // getNumbers function definition
{
    int result;

    printf("Please enter the contact's cell phone number: ");
    scanf("%s", numbers->cell);
    clear_buffer(stdin);


    if(yes("Do you want to enter a home phone number? (y or n)"))
    {
        printf("Please enter the contact's home phone number: ");
        scanf("%s", numbers->home);
        clear_buffer(stdin);
    }

    if(yes("Do you want to enter a business phone number? (y or n)"))
    {
        printf("Please enter the contact's business phone number: ");
        scanf("%s", numbers->business);
        clear_buffer(stdin);
    }
}

于是我继续复制同样的想法:

void getNumber(struct Number *num) {
    int response;
    printf("Please enter the contact's cell phone number: ");
    scanf("%10s", num->cell); // I changed this line from:
//  *num->cell = getInt();


    printf("Do you want to enter a home phone number? (y or n): ");
    response = yes();

    if (response == 1) {
        printf("Please enter the contact's home phone number: ");
        scanf("%10s", num->home); // I changed this line from:
//  *num->home = getInt();
    }

    printf("Do you want to enter a business phone number? (y or n): ");
    response = yes();

    if (response == 1) {
        printf("Please enter the contact's business phone number: ");
        scanf("%10s", num->business); // I changed this line from:
//  *num->business = getInt();
    }
}

可能getInt函数不适合定义。我不知道该如何解释,但这是可行的。

谢谢大家。
