Numbered individuals and a city circle, 37 (1 ~ 37), the first man since 1 number, count to five wer-CodePudding

The header file: # include

Define functions: int fflush (FILE * stream);
Function description: fflush () will force the data within the buffer to write back to stream specifies the file and stream if the parameter is NULL, fflush () will all open files data update,
Return value: failed to successfully returns 0, returns EOF, the error code stored in errno,
Fflush () can also be used for the standard input (stdin) and standard output (stdout), used to empty the standard input and output buffer,
Stdin is the standard input, namely the standard input, generally refers to the keyboard; Standard input buffer is used to the staging of the content of the input from the keyboard buffer, stdout is standard output, or standard output, generally refers to a display; The standard output buffer is used to display the contents of the buffer, temporary will

Empty the standard output buffer,
Refresh the output buffer, the buffer output to the screen
If in parentheses is already open file pointer, then the content of the output buffer is written to the file pointer to, or removal of the output buffer,
The stdout is the standard output file pointer system definition, by default refers to the screen, that is to write the contents of the buffer on the screen,
But from the code is not to find out what will buffer content, so it didn't work

Rewind to clear the standard input (stdin) key buffer

CodePudding user response:

 fflush () can also be used for the standard input (stdin) and standard output (stdout), used to empty the standard input and output buffer

The fflush (stdin); Some compilers may effectively under Windows, is not equal to other compilers must also effective; Limited by certain compiler ~
