这是Keil C51中的两个例子

#include <reg52.h>
#include <stdio.h>
struct stu
{
  unsigned char name[10];
  unsigned long num;
  float score;
}p1[3];
void main(void)
{
  unsigned char i,j,maxi;
  float max;
  SCON=0x52;
  TMOD=0x20;
  TH1=0XF3;
  TR1=1;
  printf("input 3 students' name ,number and score:\n");
  for(i=0;i<3;i++)
  {
    printf("input name:\n");
    scanf("%s",p1[i].name);
    printf("input number:\n");
    scanf("%ld",&p1[i].num);
    printf("input score:\n");
    scanf("%f",&p1[i].score);
  }
  
}
