Question

C语言关于文件操作

#include <stdio.h>
#include <stdlib.h>
#include<string.h>

int save_as(char filename[]) //保存文件
{
NODE *p;
FILE *fp;
int i=0,j=0;
char str[100];
char tmpname[51];

if(filename[0]!='/') //是否根目录
{
strcpy(tmpfile,filename);
}
else
{
strcpy(tmpfile,&filename[1]); //第2个元素的地址给tmpfile
chdir("/"); //当前目录改为根目录
i=0;
do
{
if(tmpfile[i]=='/') //j组成后的新串，i是载取的位置
{
j=i;
i=0;
*(tmpfile+j)='\0'; //取出前面
if(chdir(tmpfile))
{
mkdir(tmpfile);
chdir(tmpfile);
}
strcpy(tmpfile,tmpfile+j+1);
}
i++;
}while (tmpfile[i]!='\0');

}
}

出错提示:
1.c:1338: warning: passing arg 1 of `strcpy' from incompatible pointer type
1.c:1342: warning: passing arg 1 of `strcpy' from incompatible pointer type
1.c:1347: subscripted value is neither array nor pointer

这到底哪错了啊>?

Answer 1

subscripted value is neither array nor pointer

下标值不是数组或者指针。。。

invalid lvalue in assignment

无效左值。。。
