c代码记录之利润计算

解题思路:

注意事项:

题目要求输出整数，而利率是浮点数，乘出来的利润也是浮点数。所以这里用了（int）（利润），强制把浮点数转换为整数

参考代码:

#include<stdio.h>
int main()
{
    unsigned int i;
    scanf("%d",&i);
    if(i<=100000)
        printf("%d",(int)(i*0.1));
    else if(100000<i&&i<=200000)
        printf("%d",(int)(10000+(i-100000)*0.075));
    else if(200000<i&&i<=400000)
        printf("%d",(int)(17500+(i-200000)*0.05));
    else if(400000<i&&i<=600000)
        printf("%d",(int)(27500+(int)(i-400000)*0.03));
    else if(600000<i&&i<=1000000)
        printf("%d",(int)(33500+(i-600000)*0.015));
    else
        printf("%d",(int)(39500+(i-1000000)*0.01));
	return 0;
}
