C语言程序设计教程（第三版）课后习题5.8 （C语言代码）

解题思路:
用if写的代码
注意事项:

参考代码:

# include<stdio.h>

void main()

{

int L,J;

scanf("%d",&L);

if(L<1E5)

J = L*0.1;

else if(1E5<L&&L<=2E5)

J = 1E5*0.1+(L-1E5)*0.075;

else if(2E5<L&&L<=4E5)

J = 1E5*0.1+1E5*0.075+(L-2E5)*0.05;

else if(4E5<L&&L<=6E5)

J = 1E5*0.1+1E5*0.075+2E5*0.05+(L-4E5)*0.03;

else if(6E5<L&&L<=1E6)

J = 1E5*0.1+1E5*0.075+2E5*0.05+2E5*0.03+(L-6E5)*0.015;

else if(L>1E6)

J = 1E5*0.1+1E5*0.075+2E5*0.05+2E5*0.03+4E5*0.015+(L-1E6)*0.001;

printf("%d",J);

}
