函數calculatePrice的類型沖突的錯誤

Question

我編寫了此編碼，然后說“ calculatePrice”的[Error]沖突類型存在錯誤。 我不知道為什么它似乎是一個錯誤。 誰能幫我糾正此錯誤？ ：（（

void Add(struct data* m[])//, struct data* s)
{
    char cust, choice1, choice2;
    int i, counter = 0;
    double totPrice = 0.00;


    do
    {           
        printf("Member(M) / Student(S) / Regular Customer(R)?");
        scanf("%c", &cust);

        printf("Enter name: ");
        scanf("%s", &m[counter]->Mname);

        printf("Enter phone number : ");
        scanf("%s", &m[counter]->MphoneNum);

        printf("Enter id : ");
        scanf("%s", &m[counter]->Mid);

        printf("Enter address");
        scanf("%s", &m[counter]->Maddress);

        printf("Enter e-mail : ");
        scanf("%s", &m[counter]->mail);

        do
        {
        /*  totPrice +=*/ calculatePrice(cust);

            printf("Wanna add another order?");
            scanf("%s", choice1);
        }           
        while(choice1 == 'Y');


        counter++;
        m[counter]->payment = totPrice;

        printf("Wanna add another customer?");
        scanf("%s", choice2);
    }

    while(choice2 == 'Y');  
}

double calculatePrice(char cust)
{
    char code[4], size, top;
    double discount, drPrice, topPrice, price;

    if(cust == 'M')
    //searchMember(&m, &s); 
        discount = 0.8;         

    else if(cust == 'S')
        discount = 0.85;

    else if(cust == 'R')
        discount = 0.0;


    printf("Enter the order's code :");
    scanf("%s", code);

    printf("Enter size of cup : ");
    scanf("%s", size);

    printf("Enter topping : ");
    scanf("%s", top);

    if((strcmp(code, "T1")) || (strcmp(code, "T2")) || (strcmp(code, "T3")) ||(strcmp(code, "T4")) || (strcmp(code, "T5")) == 0)
    {
        if(size == 'R')
            drPrice = 4.90;
        else
            drPrice = 5.90;
    }

    else if((strcmp(code, "CH1")) || (strcmp(code, "CH2")) || (strcmp(code, "CH3")) || (strcmp(code, "CH4")) || (strcmp(code, "CH5")) == 0)
    {

    else if((strcmp(code, "C4")) == 0)
        drPrice = 4.90;

    if(top == 'B' || top == 'G' || top == 'J' || top == 'P' || top == 'A')
        topPrice = 0.60;

    else if(top == 'X')
        topPrice = 0.00;

    price = discount * (topPrice + drPrice);

    return price; //return value
}

Answer 1

在該函數中， calculatePrice

printf("Enter size of cup : ");
scanf("%s", size);

printf("Enter topping : ");
scanf("%s", top);

要求輸入字符串，但是目標類型是char 。

應該

printf("Enter size of cup : ");
scanf(" %c", &size);

printf("Enter topping : ");
scanf(" %c", &top);

請注意%c之前的空格，它將清除上一個輸入之后剩余的空白。

另外請注意， char code[4]只能接受3個字符。 由於您不限制輸入長度，因此這是一種危險的處理方式。
