s_gets函数的应用：
#include<stdio.h>
#include<string.h>
char* s_get(char *, int );
int main()
{
char st1
[2] ="s";
s_get(st1
, 4);
printf("%s\n", st1
);
return 0;
}
char* s_get(char* str
, int n
)
{
char* rel_val
;
char * find
;
rel_val
= fgets(str
, n
, stdin);
printf("255\n");
if(rel_val
){
find
= strchr(str
, '\n');
if(find
)
*find
= '\0';
else
while(getchar() != '\n')
{
printf("11\n");
continue;
}
}
printf("&&%d\n", 12);
return rel_val
;
}
char st1[2] ="s";
s_get(st1, 4);
将换成：
char * st1 = "asga”;
则无法正常输出，所以认为s_get的char*参数要是数组的的地址，但char* st1 ="sgas";也是数组啊？
