}}</ref> Its prototype is as follows:
:<code>int putchar (int character)</code>

The character to be printed is fed into the function as an argument, and if the writing is successful, the argument character is returned. Otherwise, ] is returned.

The <code>putchar</code> function is specified in the ] ] ].

==Sample usage==
The following program uses <code>]</code> to read characters into an array and print them out using the <code>putchar</code> function after an ] character is found.

<source lang="c">
#include <stdio.h>

int main(void)
{
char str;
int ch, i, n = 0;
while ((ch = getchar()) != EOF && n < 1000)
str = ch;
for (i = 0; i < n; ++i)
putchar(str);

putchar('\n'); /* trailing '\n' needed in Standard C */
return 0;
⚫ }
</source>

The program specifies the reading length's maximum value at 1000 characters. It will stop reading either after reading 1000 characters or after reading in an end-of-file indicator, whichever comes first.

Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:
  • With history: This is a redirect from a page containing substantive page history. This page is kept as a redirect to preserve its former content and attributions. Please do not remove the tag that generates this text (unless the need to recreate content on this page has been demonstrated), nor delete this page.
    • This template should not be used for redirects having some edit history but no meaningful content in their previous versions, nor for redirects created as a result of a page merge (use {{R from merge}} instead), nor for redirects from a title that forms a historic part of Misplaced Pages (use {{R with old history}} instead).
  • To an embedded anchor: This is a redirect from a topic that does not have its own page to an embedded anchor on the redirect's target page.
    • An {{anchor|(anchor name)}} or {{visible anchor}} template, a HTML element with id="(anchor name)", or an |id=(anchor name) parameter might be installed at the beginning of a paragraph, in or near a section header or within a table. The anchor might also be an old section header that has been edited and is anchored within or near the new header to prevent broken internal and external links.
    • Even though section headers of the general form ==(Header name)== are themselves a type of anchor, use {{R to section}} instead.
When appropriate, protection levels are automatically sensed, described and categorized.
