错在哪里了
求解答

Answer 1

printf写错了，printf(:Data Error!) 没引号呀

 
#include<stdio.h>
int main()
{
    int dengji,shuliang;
    scanf("%d %d",&dengji,&shuliang);
    switch(dengji)
    {
        case 1:printf("%.2lf",5.50*shuliang);break;
        case 2:printf("%.2lf",4.30*shuliang);break;
        case 3:printf("%.2lf",3.00*shuliang);break;
        case 4:printf("%.2lf",2.50*shuliang);break;
        default:printf(":Data Error!");break;
    }
    return 0;
}
