The fflush() function is only meant to be used on streams open for output, not input. Both fflush(stdin) and fflush(NULL), in some C libraries, will flush stdout and stderr, but this is completely unportable! T
It's extremely easy to get stuck on the fact thatfflush(stdin), for some presumably stupid and pedantic reason, is not guaranteed to work everywhere. One then starts casting about looking for a “portable” replacement. The problem is that, depending on precisely what one is trying to do, ...

fflush(stdin); getch(); } void add() { int a, b, sum; cout<<"Enter two numbers:"; cin>>a>>b; sum=a+b; cout<<endl; cout<<"Sum of two numbers is: "<<sum<<endl; } Now if you see in the preceding code, I have optimized it by putting that addition lo...
Moreover I can't understand why fflush(stdin) doesn't have any effect on the output when you type a string like("bytes")an d then press enter. Code: #include <stdio.h> /* count characters in input; 2nd version */ void main() { int nc; for (nc = 0;getchar()!=EOF;nc++) ...
What's new and what changed in 1.7.31 Improve performance of send(2), sendto(2), sendmsg(2) when using small input buffers. The default pthread_mutex type is now PTHREAD_MUTEX_NORMAL, rather than PTHREAD_MUTEX_ERRORCHECK, just as on Linux. ...
? 1 fflush(stdin) 可是這個命令在linux下是通不過的,為了使用代碼更具有通用性,我們可以將其換為 ? 1 fgectc(stdin) fgectchc的作用是返回stream流的下一個字符,返回類型為unsigned char(被轉換為int類型),如果到達文件末尾或發生錯誤, 則返回EOF。 具體可以參攷這扁文章http://is.gd/FUcpxb 最後呼籲釋放艾...
