When I was making my first game I needed to get the player's initials for the high score board. But when I went to code that part of the program I had trouble figuring out how to get only 3 characters. Eventially I ended up coding a rather messy function that used keyboard scancodes to get a max of 3 characters from the keyboard. Is there a an easier way to get text input with length limitations?

This piece of code I made copies the first 3 characters of the string ‘a’ into the string ‘b’ using the strncpy() function found in the string header file which you can include like this: #include <string>.

+ Code Snippet

#include "DarkSDK.h"
#include <string>


void DarkSDK ( void )
{
	dbPrint("Enter in a string:");
	char* a = dbInput(); // get some keyboard input
	char b[256]=""; // create a new array
	
	strncpy(b,a,3); // copy the first 3 charactors of a into b

	dbPrint("The first 3 charactors of a were copied into b: ");
	dbPrint(b);

	dbSuspendForKey(); // wait for a keypress

	return;
}

That looks good, but the trouble wasn't keeping the amount of characters in memory down. I need to be able to keep the amount of characters seen on the screen to a certain amount for graphical reasons.
