今天身体不适，简单接触了点指针

#include<stdio.h> 
void upCopy(char *neW,char *old)
{   
while(*old!='\0') 
{   
if(*old>='A'&&*old<='Z')   
*neW++=*old; 
old++;  
}  
*neW='\0';
} 


main() 
{  
char s1[100],s2[]="I Love You",*p1,*p2; 
p1=s1;  
p2=s2;  
upCopy(p1,p2);  
printf("The old string is :%s\n",s2);   
printf("The new string is :%s\n",s1); 
}
