一些简单的c51程序

#include<stdio.h>
#include <reg51.h>
       int maxmum(int x,int y,int z);
       int main()
       {
          int i,j,k;
          SCON = 0x50; 
TMOD |= 0x20; 
TH1 = 0xf3; 
TR1 = 1;
TI = 1; 
		  
		  printf("i,j,k=?\n");
          scanf("%4d%4d%4d",&i,&j,&k);
          maxmum(i,j,k);
          getchar();
          printf("The maxmum value of the 3 data is %d\n",maxmum(i,j,k));
          return 0;
     }

    int  maxmum(int x,int y,int z)
     {
          int max;
          max=x>y?x:y;
          max=max>z?max:z;        
}
