我不确定您用什么语言编写此代码，但这是您用 C 语言编写的解决方案。请记住，这是使用整数，而不是浮点数。所以答案将被截断。教科书中的问题说假设整数条目，因此我这样做了。

    int main()
{
    printf("Please enter your income: ");
    int iIncome = 0;
    int iTaxAmount = 0;
    char iChecking = 0;

    //use a while loop with our scanf to make sure a valid number is input.
    while (iChecking == 0)
    {
        scanf("%d", &iIncome);
        if (iIncome <= 0)
        {
            printf("Please enter a positive, nonzero number\n");
            printf("Please enter your income: ");
        }
        else
        {
            iChecking = 1;
        }
    }


    if (iIncome < 50000)
    {

        iTaxAmount = iIncome * 0.05;
    }
    else if (iIncome < 100000 && iIncome >= 50000)
    {
        //set base amount
        iTaxAmount = 2500;
        int iTaxableOver50k = 0;
        //calculate taxable amount over 50k
        iTaxableOver50k = iIncome - 50000;
        //add base tax to percent value
        iTaxAmount = iTaxAmount + iTaxableOver50k * 0.07;
    }
    else if (iIncome >= 100000)
    {
        //set base tax amount
        iTaxAmount = 6000;
        int iTaxableOver100k = 0;
        //calculate taxable amount over 100k
        iTaxableOver100k = iIncome - 100000;
        //add base tax to percent value
        iTaxAmount = iTaxAmount + iTaxableOver100k*0.09;
    }

    printf("\nYou must pay: $%d in tax\n", iTaxAmount);

    return 0;
}

这是您使用浮点计算得出最终答案的解决方案。

#include <stdio.h>

int main()
{
    printf("Please enter your income: ");
    int iIncome = 0;
    float iTaxAmount = 0.0f;
    char iChecking = 0;

    //use a while loop with our scanf to make sure a valid number is input.
    while (iChecking == 0)
    {
        scanf("%d", &iIncome);
        if (iIncome <= 0)
        {
            printf("Please enter a positive, nonzero number\n");
            printf("Please enter your income: ");
        }
        else
        {
            iChecking = 1;
        }
    }


    if (iIncome < 50000)
    {

        iTaxAmount = (float)iIncome * 0.05f;
    }
    else if (iIncome < 100000 && iIncome >= 50000)
    {
        //set base amount
        iTaxAmount = 2500;
        int iTaxableOver50k = 0;
        //calculate taxable amount over 50k
        iTaxableOver50k = iIncome - 50000;
        //add base tax to percent value
        iTaxAmount = iTaxAmount + (float)iTaxableOver50k * 0.07f;
    }
    else if (iIncome >= 100000)
    {
        //set base tax amount
        iTaxAmount = 6000;
        int iTaxableOver100k = 0;
        //calculate taxable amount over 100k
        iTaxableOver100k = iIncome - 100000;
        //add base tax to percent value
        iTaxAmount = iTaxAmount + (float)iTaxableOver100k*0.09f;
    }


    printf("\nYou must pay: $%.2f in tax\n", iTaxAmount);

    return 0;
}
