title: Difference between putchar(), putch(), fputchar()?
body: <p>I read these concepts from the book and I searched a lot on internet too but there is no good definition and explanation available. Everywhere it is just written that <code>putch()</code>, <code>putchar()</code> and <code>fputchar()</code> work in the same way and are used to print character to console but I think there must be some different between them ?</p>
