Thread: Cin Maximum characters.

I was wondering if theres a way to have a maximum ammount of characters when using cin, also is there a way to change the text color, and the background color of the command prompt window?

Check MSDN.com. With <windows.h> included, you can change text colors and such, I believe.

And the way to have a max amount of characters is cin.getline(string,MAX,term_char)

Code:

cin.getline(myString,100, '\n');

As to the first question, I am not sure, but my guess is that the answer lies somewhere in numeric_limits.

I did try using the textcolor function, but I get errors when I compile. Im using Microsoft Visual C++.

Dont see whats wrong here.

Code:

#include <iostream>
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
using std::cout;
using std::cin;
char command;
int ch;
// Inpute Function. checks all input.
void inpute()
{ 
textcolor ( MAGENTA );
cprintf ( ">> \n" );
cprintf ( ">> "  );
}

I get these errors

Code:

c:\documents and settings\blade-new\my documents\visual studio projects\admin\funcs.h(12) : error C2065: 'textcolor' : undeclared identifier
c:\documents and settings\blade-new\my documents\visual studio projects\admin\funcs.h(12) : error C2065: 'MAGENTA' : undeclared identifier

Error executing cl.exe.

ADMIN.exe - 2 error(s), 0 warning(s)

Oh, yes I see, but theres only 3 colors . Thanks though
