[编程入门]利润计算

解题思路:

注意事项:

参考代码:

#include<stdio.h>

int fun(int x)

{

int a=100000;

if(x<=a)

{

return 0.1*x;

}

else if(x<=2*a){

return 0.1*a+0.075*(x-a);

}

else if(x<=4*a){

return 0.1*a+0.075*a+0.05*(x-2*a);

}

else if(x<=6*a){

return 0.1*a+0.075*a+0.05*2*a+(x-4*a)*0.03;

}

else if(x<=10*a){

return 0.1*a+0.075*a+0.05*2*a+0.03*2*a+(x-6*a)*0.015;

}

else{

return 0.1*a+0.075*a+0.05*2*a+0.03*2*a+4*a*0.015+0.01*(x-10*a);

}

}

int main()

{

int x,y;

scanf("%d",&x);

y=fun(x);

printf("%d",y);

return 0;

}
