All the characters have ASCII value associated with it in C programming. So internally it checks the ASCII value of user entered character against the ASCII values of “A” to “Z”. ASCII value range of upper case alphabets:ASCII value of A is 65.ASCII value of B is 66.ASCII value of...
on the same line of the output (eg. HelloC:\or Helloarmy1987@a rmy1987-laptop:~$ or whatever). Anyway, if you're going to use that in a longer program, this forces the output to be shown immediately (this is only required when newlines are printed and stdout is interactive). This...
or 'a+' or 'ab+' modes), flushing written output data before starting to read from the stream is mandatory. In such an instance, fflush() itself does not necessarily have to appear: fseek() will also trigger the necessary flushing. -- Programming is what happens while you're busy makin...
In C programming, thefflush(stdin)function is used to clear the input buffer memory of any data that may still be stored. It does this by freeing up any memory associated with the standard input stream, known as stdin, which is the default input used for reading any data from command lin...
(stdin), despite the fact that this is a misguided application of the standardfflushfunction, an application that is not guaranteed to (and in fact most certainly does not) work everywhere. But it “works” under a large number of popular PC C compilers, so the “idiom” is, unfortunately...
