1010: [编程入门]利润计算

解题思路: 中学的应用题,很明显的分段函数(选择结构)

注意事项: 有6个区间 要注意区间划分 每个区间函数不同 要顺清思路 

参考代码:

#include<stdio.h>

int main()

{

    int l, bonus, bouns1, bouns2, bouns3,bouns4,bouns5,bouns6;

    scanf("%d", &l);

    bouns1 = l / 10;

    bouns2 = 10000 + 0.075*(l - 100000);

    bouns3 = 17500 + 0.05*(l - 200000);

    bouns4 = 27500 + 0.03*(l - 400000);

    bouns5 = 33500 + 0.015*(l - 600000);

    bouns6 = 39500 + 0.01*(l - 1000000);

    if (l <= 100000)

    {

        printf("%d", bouns1);

    }

    else if (l > 100000 && l <= 200000)

    {

        printf("%d", bouns2);

    }

    else if (l > 200000 && l <= 400000)

    {

        printf("%d", bouns3);

    }

    else if (l > 400000 && l <= 600000)

    {

        printf("%d", bouns4);

    }

    else if (l > 600000 && l <= 1000000)

    {

        printf("%d", bouns5);

    }

    else if ( l > 1000000)

    {

        printf("%d", bouns6);

    }

}
