==Description==

This example shows an easy and common way to store a string (e.g. for the application version) and printing it out.

==Source Code ==

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

int main(void)
{
char *version = "1.0";

u_long baud = 115200;

NutRegisterDevice(&DEV_DEBUG, 0, 0);
freopen(DEV_DEBUG_NAME, "w", stdout);
_ioctl(_fileno(stdout), UART_SETSPEED, &baud);

printf("Application version: %s\n", version);

for(;;);
return 0;
}

</source>

==Output==

Application version: 1.0

==Details==

<source lang="c">
char *version = "1.0";
</source>

defines a pointer to the type char, which points to an adress in memory where the string "1.0" is stored.

<source lang="c">
printf("Application version: %s\n", version);
</source>

now prints out the string stored at the adress, the <code>version</code> pointer provides.
