统计文件字符数

[onion____]

#include<stdio.h>
#include<stdlib.h>
int main()
{
int i=0;
char ch,filename[256];
FILE *in,*out;
if((in=fopen("123.txt","r"))==NULL) \\输入文件名 复制123.TXT
{
printf("cannot open the file");
exit(0);
}
printf("Enter the name of copy\n"); \\输入文件名 复制123.TXT
scanf("%s",filename);
if((out=fopen(filename,"w"))==NULL)
{
printf("cannot open the file");
exit(0);
}
while(!feof(in))
{
fputc(fgetc(in),out);
}
fclose(out);
if((out=fopen(filename,"w"))==NULL)
{
printf("cannot open the file");
exit(0);
}
ch=fgetc(out);
while(ch!=EOF)
{
i+=1;
}
printf("%d\n",i);
fclose(in);
fclose(out);

return 0;
}

输入文件名 复制123.TXT 输入文件名 复制123.TXT 然后想统计TXT中字符个数 为何不能实现？

while(ch!=EOF)
{
i+=1;
}
这一句是什么?
死循环吗?

	ch=fgetc(out); 
	while(ch!=EOF) 
	{ 
		if(ch!='\n')
			i+=1; 
		ch=fgetc(out);
	} 

这样不统计每行的最后一个回车符
