hi,
here is the program:

/*file:avrage.c*/
#include<stdio.h>

/* calculate the average of three numbers */
void main()
{
int num1, num2, num3;
float avg;

printf("enter 3 integer numbers:");
scanf(" %d %d %d ", &num1, &num2, &num3);


avg = num1+num2+num3;

avg = avg/3;

printf("the average is:%f",avg);

}
dumb question: what to do after i entered the numbers in TC++ "run" window? because pressing the "Enter" button does nothing.

brilliant!!
thank you very much

2 basic questions:

1)is there any function that will except hitting "Enter", and not an actual character to display the average?

2)is there a way to clear the "run" window, and the "user screen" window, without restarting Turbo C++ ?

Question #1 I am not sure I understand. Did you mistype 'accept'? What exactly you need to do? Also, the average displayed BEFORE you hitting any keys. Also, you can easily input ENTER instead of any other character - it will work the same way.

Question #2.

Simply call function clrscr() and it will clear the screen.

1# yes sorry - i mistyped 'accept'.
and for me the average does not display before i hit any keys. after i insert the numbers i must hit a letter key (doesn't matter which one) and then ENTER - only then will i see the average...

2# - thanks - it worked

Wow! You are correct!
I just tried this code on my TC 201 and indeed you need
to enter something before seeing the average value.

I found the cause, however.

The formatting string is " %d %d %d ".
Notice the blanks on both sides. Simply remove them.
The formatting string is now "%d %d %d". And the problem is gone!
It is most likely the bug in Turbo C itself.
I am not sure the C/C++ standard has anything to say about this behavior, so it is most likely a bug in TC. Well, it was long ago.

I have added some colors to your program.
Have fun!

/*file:avrage.c*/

#include <stdio.h>
#include <conio.h>
#include <bios.h>

 /* calculate the average of three numbers */
 void main()
 {
 	int num1, num2, num3;
 	float avg;

	textcolor (WHITE);
	cprintf("\r\nenter 3 integer numbers: ");
	textcolor (LIGHTGREEN);
	cscanf("%d %d %d", &num1, &num2, &num3);


 	avg = num1+num2+num3;

 	avg = avg/3;

	textcolor (YELLOW);
	cprintf("\r\nthe average is:%f",avg);

	bioskey (0);
	textcolor (LIGHTGRAY);
 }

If you want to know where all those functions come from - simply put cursor on a name of any function or constant, like YELLOW, and press CTRL+F1.

Awesome! It worked!
Nice debugging skills man

And the colors are much better thank you...

You've been a great help man. Much much appreciated

You can also do graphics programs and it will all work in Win XP DOS box. Here is how to discover functions for it:

#include <graphics.h>

Then put a cursor on 'graphics.h' and press CTRL+F1 - it should give the list of functions in that header. Read on!

Thanks, right on it!
