篇一：c语言 输出对应生日
#include <stdio.h>
void main ()
{ int no,year,month,day;//学号,生日的年月日,整形输入。
char sex;//性别
float chinese,math,english,total,average;//长整形
printf("输入学生的学号:");
scanf("%d",&no);
printf("输入学生的生日(yyyy-mm-dd):");
scanf("%4d-%2d-%2d",&year,&month,&day);//输入
fflush(stdin);//清除键盘缓冲区
printf("输入学生性别(M/F):");
scanf("%c",&sex);
printf("输入学生成绩,(语文,数学,英语):");
scanf("%f,%f,%f",&chinese,&math,&english);
