Setting the background color and running a program

[NwvkoG1T]

I use turbo c++ 3.0

Please tell me how to set the background color using the function setbkcolor() in graphics.h

will i need to run the exe file in full screen if i use this function?

1) graphics.h is outdated and you may want to look for something that would work with newer OS.
Answer to your question:

   setbkcolor(BLUE);
/* or */
 setbkcolor(1);
/*Color codes:
Name	Value
BLACK 	0
BLUE	1
GREEN	2
CYAN	3
RED	4
MAGENTA	5
BROWN	6
LIGHTGRAY	7
DARKGRAY	8
LIGHTBLUE	9
LIGHTGREEN	10
LIGHTCYAN	11
LIGHTRED	12
LIGHTMAGENTA	13
YELLOW	14
WHITE	15 */

2) Turbo C++ 3.0? Whaich museum did you rob? This compiler is 20 years old! C++ Standart undergo many changes since then and I don't think it would work well in modern OS

could not understand any other IDE that was good and at the same time simple to understand. and if i do #include<fstream.h> in code blocks then it says that there is an error. why? it is a valid header file after all?

Because there is no <fstream.h> in C++ standard. It's <fstream> actually.

well, what about this

class user
{
int t; 
char ch[10]...

public:
user()
{
strcpy(ch,'NULL');
}

now it says that strcpy has not been defined in this scope. I have included string.h. Please help.
