陷入无限循环 [英] Running into an infinite loop

问题描述

我的程序正在陷入无限循环.您能告诉我代码有什么问题吗?

Hi,

My program is running into an infinite loop. Can you please tell me what is wrong with the code?

char  ch=0;
FILE *p = NULL, *q = NULL;


p = fopen(argv[1], "r+");
q = fopen(tempfilename, "w+");
  while ((ch = getc(p)) != EOF)
    {
     // Normal if else statements

}

我也试着给..但徒劳.. :(

I also tried giving.. but in vain.. :(

int ch;

预先感谢，

Thanks in advance,

推荐答案

代码没有错误.唯一的错误是我可以看到您不验证fopen是否可以打开文件.验证p！= NULL.如果p为null我需要问您使用的是什么编译器?可能是旧的

code has no mistake. only mistake i can see you are not verifying whether fopen can open the file or not. verify if p!=NULL. if p is null I need to ask what compiler are you using? probably old

while ( 1 )
        {
               ch = fgetc ( fs ) ;

               if ( ch == EOF )
                      break ;
               else

                       fputc ( ch, ft )  ;
        }
