本文介绍了文件问题..对_streams的定义引用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
#include < stdio.h >
#include < stdlib.h >
#include < string.h >
int main（）{
FILE * fp1，* fp2;
char ch;
fp1 = fopen（ TEST.txt， w）;
if （fp1 == NULL）
{
printf（ 无法打开文件）;
退出（ 1 ）;
}
printf（ 输入要退出的字符输入$）;
do
{
ch = getchar（）;
if （ch！= ' $' ）;
putc（ch，fp1）;
} while （ch！= ' $ ）;
fclose（fp1）;
fp2 = fopen（ TEST.txt， r）;
if （fp2 == NULL）
{
printf（ 无法打开FIlE来读取）;
退出（ 1 ）;
}
int charcount = 0 ;
while （！feof（fp2））
{
ch = getc（fp2）;
printf（ ％c，ch）;
charcount ++;
}
printf（ \ nCount of characters =％c \ N，charcount）;
fclose（fp2）;
return 0 ;
}
我得到的错误：
