Question

当我尝试扫描输入收入的值时，我遇到了错误，这段代码有什么问题？我认为它与使用收入两次有关，我可以简单地改变变量的名称，是他们解决这个问题的另一种方法吗？

#include <stdio.h>

float TaxDue(float income){
    float tax = 0;

    if (income < 0){
        printf("\nYou've Enter A Negative Income");
    }
    else if (income <= 750){
        tax = (income * .01);
    }
    else if (income <= 2250){
        tax = 7.50 + ((income - 750) * .02);
    }
    else if (income <= 3750){
        tax = 37.50 + ((income - 2250) * .03);
    }
    else if (income <= 5250){
        tax = 82.50 + ((income - 3750) * .04);
    }
    else if (income <= 7000){
        tax = 142.50 + ((income - 5250) * .05);
    }
    else if (income > 7000){
        tax = 230.00 + ((income - 7000) * .06);
    }
    else{
        printf("\nError");
    }

    return tax;
}

int main(void){
    float income = 0;

    printf("Enter Your Taxable Income: ");
    scanf("%f", income);
    printf("\nYou Owe %f In Taxes", TaxDue(income));

    return 0;
}

Answer 1

在main中更改以下语句：

scanf("%f", income);

作为

scanf("%f", &income);

在C中使用函数
