printing 0 to 1000 in console screen..

[telephone]

can we write a c code in turboc++(3.0 dos version) which will print the numbers
consequently from 0 to 1000 on the console screen or output screen
provided that we can use only the following system define functions....
1) printf();
2)exit();
3)delay();
4)clrscr();

and it is also provided that the c program will not contain
any loop statement(ie.for loop,while loop,dowhile loop),any ternery operator,
any if else statement,any switch case..........
if someone can solve it then please answer...............

The experts on this site are more than happy to help you with your problems but they cannot do your assignment/program for you. Attempt the assignment/program yourself first and post questions regarding any difficulties you have or about a particular function of the code that you don't know how to achieve.

Please read the Posting Guidelines and particularly the Coursework Posting Guidelines.

Then when you are ready post a new question in this thread.

we can,by using recursive function.print the value of variale,increment it,pass to function recursively.

Use a recursive function.

At first I thought it might be impossible without an "if statement".
But then I remembered &&., and applied recursion using that logic.

I was able to complete the task.
I would be interested in hearing from the experts tho, what tricks they would use. PM if you feel it would reveal too much.

A for loop. Why purchase, set up, learn and use the HYDRO SUPER DICER KITCHEN SUPER SET THAT CUTS, FILLETS, AND MINCES ALL AT THE SAME TIME when you can use a regular knife?

Optimization tricks are good to know and implement in the right place, but should not be used in place of good coding practices - it just makes your life harder later.

Or you could use the || operator rather than &&

However by far the simplest way is to call to printf 1001 times, once for each line of output or even call printf once with a very long string would do the trick.

You don't appear to have be limited to having to use an integer variable to contain the number!

Or you can use a goto statement instead of recursion but the only way I found to exit was to not included stdlib.h so the compiler wasn't aware that exit returns void so I could using it as 1 side of a logical expression :D

And there is always the possibility of purposefully creating a SEGFAULT to halt the program hehe although of course that is actually undefined behaviour so not completely guaranteed.

Ah, now that is a neat idea... I had the same problem when I tried to do a logical expression with a WriteLine statement, so I just moved it to a different line. But, It would be neat to know how to "trick" the compiler into converting a function that has void as a return type into a function that returns a value.

OK I MUST caution you on this point. The compiler does not "convert" a void function to a function that returns an value. It just treats it as though it returns a value even though it doesn't.

This is almost certainly undefined behaviour and I would NEVER use such a technique in a serious project or program.

I only suggested it here because this is one of those stupid questions we see educational establishments asking from time to time that imposes a completely unrealistic set of restrictions in an effort to force their students to use some unmentioned technique, presumably one they have just learnt, but since we don't attend their classes we don't have that information.

can anybody show me the code with && or || operators.coz,i didn't get it.
