fantasyemperor你的也有错
#include<stdio.h>
void main()
{
int x,e;
double a,sum,rate;
e=x/5;
switch(e){
case 0:
rate=0;
break;
case 1:
rate=0.01;
break;
case 2:
case 3:
rate=0.02;
break;
case 4:
case 5:
rate=0.04;
break;
default:
rate=0.06;
}
sum=a*x(1-rate);
}
function不对，你运行看看，我不懂啦

[gankailan]

sum=a*x(1-rate);
不适合switch吗

原来是后续。。。 帮顶~

[gankailan]

#include<stdio.h>
void main()
{
int x,e;
double a,sum,rate;
printf("\n请输入数量和单价: ");
scanf("%d%lf",&x,&a);
e=x/5;
switch(e){
case 0:
rate=0;
break;
case 1:
rate=0.01;
break;
case 2:
rate=0.02;
break;
case 3:
rate=0.04;
break;
default:
rate=0.06;
}
sum=a*x*(1-rate);
printf("\n应付金额为: %lf",sum);
}
这下对了吧，^_^^_^
