I think it is next to impossible to solve the puzzle 9 without using getch/getche (Which r in "conio.h ") because without it one can't read sentence 'word by word'

So please can we use getch/getche?

what....

getch() and getche() comes under stdio.h

wait let me confirm it.....

QwertyManiac · Dec 10, 2007

Under Turbo stuff, getch() comes in conio.h

adi007 · Dec 10, 2007

confirmed...
getche() and getch() comes under stdio.h(tested in TC++ 3.0)..

If you cannot tell ANSI/ISO standard C from a system-dependent implementation (i.e., Turbo C++), you ought to invest more time in learning the language rather than posting non-standard, useless, and tricky puzzles here.

no adi. it cant be!:shocked: i checked it again now n its comes in conio.h only!!n i hav the same tc as urs. even in the help file of tc its mentioned conio.h!!

adi007 · Dec 10, 2007

hmmm..

i created the solution program by using conio.h for clrscr()
then i removed clrscr() and #include<conio.h>
then i made some modifications to the solution program and compiled it...
It worked fine..
I tested the program by using both getch() and getche() without using conio.h and it worked....

wait ..
I will confirm it later by creating the program from the scratch......

Yamaraj · Dec 10, 2007

What is there to confirm? You should not have skipped studying the C Standard Library while you were busy mastering the syntax.

Non-standard and system/implementation dependent functions like getch(), getche() or clrscr() CANNOT reside in a standard header like stdio.h.

anuj919 · Dec 10, 2007

So what have come out all your discussion
Can we use getch/getche or not?

adi007 · Dec 11, 2007

I accept my fault....
I am extermely sorry for the mistake...
I referred the help documentation and some books and found that getch() ,getche() comes under conio.h...
So rules are modified
One can use getch(),getche() but must not use clrscr()
here are the modified rules

Rules
1.No user defined functions..
2.No usage of clrscr()
3.No header file other than stdio.h and conio.h should be used.
4.No * symbol in the whole program

Now i let me explain why i commited such a big mistake..

I am using TC++ 3.0 for the past 3 years and have never used conio.h for getch() and getche(). :shock:

So i thought these 2 comes under stdio.h
The following program works fine in my TC

Code:

#include<stdio.h>
void main()
{
clrscr();
printf("Press any key\n");
getche();
getch();
}

and even this works fine

Code:

void main()
{
clrscr();
printf("Press any key\n");
getche();
getch();
}

I have made the vedio file and will upload and give the link within this week...

^^^strange???

has some settings been change of ur TC++ compiler??

QwertyManiac · Dec 11, 2007

Yeah how does stdio.h cover clrscr as your code example claims so? Use standard code mate, and allow a wider population to join.

anuj919 · Dec 11, 2007

I got the answer again

But yes Adithya is true , the program works fine without including "conio.h"
& can anyone tell me that how this happens in Turbo C++ 3.0

Here is the answer:

Code:

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

void main()
{
	char b[999];
	int i=0,j=0;
	char c;

	printf("Enter the String\n");
	while((c=getche())!='')
	{
		if(c==' ')
		{
			for(j=0;j<=i;j++)
				printf("\b");
			for(j=i-1;j>=0;j--)
				printf("%c",b[j]);
			printf(" ");
			i=0;
		}
		else
			b[i++]=c;
	}
	printf("\nHave a Nice Day!");
	getch();
}

I wonder if it's of any use talking sense into people these days. Turbo C++ is NOT C or even C++. Either ask mods to change the title from "C puzzle" to "Turbo C++ puzzles", or spend some time reading the standard ANSI/ISO C and post accordingly.

People still using TC++ 3.0 should be hanged till death. Tell that to your instructor/professor.

Sykora · Dec 12, 2007

^^^ Agreed.

sorry Yamaraj..
I will take care that this will not happen again...
Will follow strict ANSI/ISO C standards from now on...
By the way which c compiler u use..?

Sorry for not giving puzzle 10 yeterday.Will give puzzle 10 tommorow...

Yamaraj · Dec 14, 2007

No need to be sorry. I only want you and others to get better at programming. I use many compilers actually - GCC (On Linux and Cygwin), MinGW (GCC for Win32), Visual C++ 2008 Express Edition, Sun C and C++ on Solaris etc.

If you want a decent ANSI/ISO conforming C compiler for Windows, try Pelles C - *www.smorgasbordet.com/pellesc/ or MinGW.

Things like unbuffered I/O, non-standards functions like clrscr() and getch()/getche() are entirely system or implementation dependent, and likely to distract a potential learner from the path of becoming a real good programmer. In fact, it's the code readability, re-usability and portability that you should be more concerned about.

Currently you are witnessing C puzzle 10

First,let me state the rules in this thread:
1.Please do not give suggestions or hints.Specify the modified program only.
2.Before posting the program make sure it's working in the way i want.

Here is the 10th C puzzle

write a c program in which tom will chase jerry for 2 lines and then jerry bounce back and will chase tom to the begining..

confused..*gigasmilies.googlepages.com/39.gif*gigasmilies.googlepages.com/39.gif

here is the output that i expect..

Note:I captured the output using camtassia but it could not capture it correctly..Even then the real output will be similar to this..

Note :Specify your modified program along with the answer

Two lines as in two physical lines or prompt/terminal width dependent? Cause I see your 'Jerry' trickling down to the 2nd line character by character.

Execute in Turbo C only
You must first save this file in TC directory ONLY save as .C file and then run it in TC
if you save as .CPP then it won't execute

so some graphics in C

Code:

/* Execute in Turbo C only 
You must first save this file in TC directory as NAME.C only and then run it in TC
if you save as .CPP then it won't execute   */

#include <graphics.h>
#include <dos.h>
#include <conio.h>
main()
{
    int gd=DETECT,gm,button,x,y,x2,y2,i;
    char a;
    x=0;y=0;

    initgraph(&gd,&gm,"");
    setcolor(2);
    setfillstyle(SOLID_FILL,BLACK);
    outtextxy(50,400,"Keep holding Space For Tom to Chase, Any key to Exit ");
    outtextxy(50,430,"hell with the rules this was made by me long back now just edited little ");
    outtextxy(50,450,"i have to study for VTU bye and btw All the best Mr Very Rude Adi");

    for(x=0;x<480;x++)
    {
    outtextxy(x,y,"Tom  Jerry");
    a=getch();
    bar(x,y,x+79,y+10);
    if(a!=' ') exit(0);
    }

    for(x=480;x>0;x--)
    {
    outtextxy(x,y+30,"Tom  Jerry");
    a=getch();
    bar(x,y,x+79,y+50);
    if(a!=' ') exit(0);
    }
    while(!kbhit());
}
