大概描述：计算分级税务要纳税多少计算一下即可

思路如下：

数组模拟计税过程即可

代码如下：

#include<stdio.h>
#include<iostream>
 
using namespace std;
 
int baseLine[7]={0, 3000, 12000, 25000, 35000, 55000, 80000};
double rate[8]={0, 3, 10, 20, 25, 30, 35, 45};
 
int CalTax(int income){
    if(income<=5000)
        return 0;
    income-=5000;
    double taxDouble=0;
    int level;
    for(level=0; level<7; level++){
        if(income>baseLine[level])
            continue;
        break;
    }
    //level==7 || income<=baseLine[level]
    for(int levelCur=1; levelCur<level; levelCur++){
        taxDouble+=(1.0*rate[levelCur]/100)*(baseLine[levelCur]-baseLine[levelCur-1]);
    }
    taxDouble+=(1.0*rate[level]/100)*(income-baseLine[level-1]);
    int taxInt=(int)(taxDouble*10);
    if(taxInt%10>=5){
        taxInt=taxInt/10+1;
    }
    else{
        taxInt=taxInt/10;
    }
    return taxInt;
}
 
int main()
{
    int N;
    scanf("%d", &N);
    for(int n=0; n<N; n++){
        int income, tax;
        scanf("%d", &income);
        tax=CalTax(income);
        printf("%d\n", tax);
    }
    return 0;
}
