Program to create tower of Hanoi in C

yle: italic;">Definition : The Tower of Hanoi or Towers of Hanoi is a mathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks in a neat stack in ascending order of size on one rod, the smallest at the top, thus making a conical shape.

#include
void hanoi_tower(char,char,char,int);
void hanoi_tower(char peg1,char peg2,char pege3,int n)
{
if(n<=0)        printf("\n Sorry Illegal Entry");        if(n==1)   printf ("\n Move disk from %c to %c", pege1,pege3);   else   {      hanoi_tower(peg1,peg3,peg2,n-1);      hanoi_tower(peg1,peg2,peg3,1);      hanoi_tower(peg2,peg1,peg3,n-1);   } }   Void main () {    int n;    printf("\n Input the number of disc:);    scanf("%d", &n);    printf("\n Tower of Hanoi for 5th DISC", n);    hanoi_tower('x','y','z',n); }

what is Debugging with GNU Debugger (GDB)

The debugger is the program that you use to figure out why your program isn’t behaving the way you think it should.You’ll be doing this a lot. The GNU Debugger (GDB) is the debugger used by most Linux programmers.You can use GDB to step through your code, set breakpoints, and examine the value of local variables.

C header files in unix & its Working

You can learn a lot about the system functions that are available and how to use them by looking at the system header files.These reside in /usr/include and /usr/include/sys. If you are getting compile errors from using a system call, for instance, take a look in the corresponding header file to verify that the function’s signature is the same as what’s listed in the man page.
On Linux systems, a lot of the nitty-gritty details of how the system calls work are reflected in header files in the directories /usr/include/bits, /usr/include/asm, and /usr/include/linux. For instance, the numerical values of signals are defined in /usr/include/bits/signum.h.
These header files make good reading for inquiring minds. Don’t include them directly in your programs, though; always use the header files in /usr/include or as mentioned in the man page for the function you’re using.
