大家看一下这是为什么

#include<stdio.h>
#include<math.h>
#define pi 3.1415926;
int main()
{
    int x;
    double y;
    int start,end,step;
    printf("请输入起始周期、终止点和步长\n");
    scanf("%d%d%d",&start,&end,&step);
    for (x=start;x<=end;x=x+step);
    {
        y=sin(x*pi/180);
        printf("%d\t\t%f\n",x,y);
        printf("\n");
    }
    return 0;
}




结果出现H:\MSDev98\MyProjects\cos3\cos3.c(13) : error C2143: syntax error : missing ')' before ';'
H:\MSDev98\MyProjects\cos3\cos3.c(13) : error C2143: syntax error : missing ';' before '/'
H:\MSDev98\MyProjects\cos3\cos3.c(13) : error C2059: syntax error : ')'
