给你一个源代码,希望对你有所帮助,你可以运行一下.
如下:

#include<stdio.h>
void movedisc(unsigned n,char fromneedle,char toneedle,char usingneedle);
int i=0;
int main()
{
unsigned n;
printf("please enter the number of disc:");
scanf("%d",&n);
printf("\tneedle:\ta\t b\t c\n");
movedisc(n,'a','c','b');
printf("\t Total: %d\n",i);
}
void movedisc(unsigned n,char fromneedle,char toneedle,char usingneedle)
{
if(n>0)
{
movedisc(n-1,fromneedle,usingneedle,toneedle);

++i;
switch(fromneedle)
{
case 'a': switch(toneedle)
{
case 'b': printf("\t[%d]:\t%2d.........>%2d\n",i,n,n);
break;
case 'c': printf("\t[%d]:\t%2d...............>%2d\n",i,n,n);
break;
}
break;
case 'b': switch(toneedle)
{
case 'a': printf("\t[%d]:\t%2d<...............>%2d\n",i,n,n);
break;
case 'c': printf("\t[%d]:\t %2d........>%2d\n",i,n,n);
break;
}
break;
case 'c': switch(toneedle)
{
case 'a': printf("\t[%d]:\t%2d<............%2d\n",i,n,n);
break;
case 'b': printf("\t[%d]:\t%2d<........%2d\n",i,n,n);
break;
}
break;
}
movedisc(n-1,usingneedle,toneedle,fromneedle);

}
}
