给你改了下,阿门,原谅我吧

# include <stdio.h>
# include <stdlib.h>
# include <ctype.h>

# define N 50

	printf("please input the %d strdents's datas(name,num,sex,scor)\n",n+1);
	printf("input name:");
	scanf("%s",stu[n].name);
	getchar();

	printf("input number:");
	scanf("%ld",&stu[n].num);
	getchar();

	printf("input sex:");

	getchar();

	printf("input score:");
	scanf("%f",&stu[n].scor);
	getchar();

	n++; // 每次newdata完了,n++
}
void output(struct stuinfo *s,int k)//输出
{
	printf("%-12s\t-8ld\t %c\t&6.2f\n",s->name,s->num,s->sex,s->scor);

}
