作了一个员工工资表：运行的时候怎么出现：先是Input name:（我就输入一个名字）但是按回车键，本想会出现Input salary:但是提示我的是下面的语句：

Input salary: scanf : floating point formats not linked Abnormal program termination

程序如下：

#include "stdio.h" struct teacher { int worknum; char name[20]; float salary; }; struct teacher s[20]; main() { int i; for(i=0;i<20;i++); { printf("Input work number:"); scanf("%d",&s[i].worknum); printf("Input name:"); scanf("%s",&s[i].name); printf("Input salary:"); scanf("%f",&s[i].salary); } for(i=0;i<20;i++) { printf("%d",s[i].worknum); printf("%s",s[i].name); printf("%f\n",s[i].salary); } }

请教各位大虾！
