这是Keil C51中的两个例子

#include <reg52.h>
#include <stdio.h>
struct student
	{
	 int num;
	 char name[10];
	 float score;
	}stu[3];
void main(void)
{
	unsigned char i,maxi,j;
	float max;
	SCON=0x52;
	TMOD=0x20;
	TH1=0XF3;
	TR1=1;
	printf("please input 3 students' num,name and score:\n");
	for(i=0;i<3;i++)
		{
		printf("num:"); 
		scanf("%d",&stu[i].num);
		printf("name:"); 
		scanf("%s",stu[i].name);
		printf("score:"); 
		scanf("%f",&stu[i].score);
		}
	for(j=0;j<3;j++)
		{
		max=0;
		if(stu[j].score>max)
			{
			max=stu[j].score;
			maxi=j;
			}
		}
	printf("%s %f",stu[maxi].name,max);
}
