1错误代码

#include<stdio.h>

int main(){
    char a[]="hello";
    char *p=a;
    for(int i=0;i<5;i++){
        printf("%c",*p+i);
    }    
    return 0;
}

输出

hijkl

2正确代码（其中之一）

#include<stdio.h>

int main(){
	char a[]="hello";
	char *p=a;
	for(int i=0;i<5;i++){
		printf("%c",*(p+i));
	}	
	return 0;
}

 输出

hello
--------------------------------
Process exited after 0.2415 seconds with return value 0

正确代码2

#include<stdio.h>

int main(){
	char a[]="hello";
	char *p=a;
	printf("%s",p);
	return 0;
}
