(c语言)本题目要求读入每月工资,计算按月需要累计缴纳的税额(税率见下图),此处只需显示应缴纳的税额,无需减去已缴纳部分。结果保留两位小数。 注意:每月有5000元免税额。 1.png

以下是C语言计算每月需要累计缴纳的税额的代码，结果保留两位小数：

#include <stdio.h>

int main() {
    float salary, tax;
    scanf("%f", &salary);
    salary -= 5000; // 减去免税额
    if (salary <= 0) {
        tax = 0;
    } else if (salary <= 3000) {
        tax = salary * 0.03;
    } else if (salary <= 12000) {
        tax = salary * 0.1 - 210;
    } else if (salary <= 25000) {
        tax = salary * 0.2 - 1410;
    } else if (salary <= 35000) {
        tax = salary * 0.25 - 2660;
    } else if (salary <= 55000) {
        tax = salary * 0.3 - 4410;
    } else if (salary <= 80000) {
        tax = salary * 0.35 - 7160;
    } else {
        tax = salary * 0.45 - 15160;
    }
    printf("%.2f", tax);
    return 0;
}
