Hanoi tower, problem with number of elements

hello! I have some problems with Hanoi Tower. I want to do that user can define number of elements (i tried printf->scanf but it doesnt work). There is only possibility to change number of elements in code but thats useless for me. Can you help me? Here is code:

Code:

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

#include <windows.h> 

HANDLE g_hConsol = GetStdHandle(STD_OUTPUT_HANDLE); 

void gotoxy(const int x, const int y) 
{ 
COORD coord = {x, y}; 
SetConsoleCursorPosition(g_hConsol, coord); 
} 


void clrscr() 
{ 
COORD ZEROPOINT={0,0}; 
DWORD written; 

FillConsoleOutputCharacter (GetStdHandle 
(STD_OUTPUT_HANDLE), ' ', 
2000, ZEROPOINT, &written); 
gotoxy (1, 1); 
} 


typedef unsigned int uint; 
//#define NUMB_OF_ELEM 10 


//int towers[NUMB_OF_ELEM][3]; 

void main2() { 
//int NUMB_OF_ELEM = 10; 
//int z; 
//scanf ("%d", &z); 

#define NUMB_OF_ELEM 6 

} 
int towers[NUMB_OF_ELEM][3]; 
void prnt() 
{ 
int j, k, posx, posy; 
int i; 

clrscr(); 

for(j = 0; j < 3; j++) { 
for(i = NUMB_OF_ELEM-1; i >= 0; i--) { 
posy = 20 - i; 
posx = 20 + (j * 20); 
for(k = 1; k <= towers[i][j]; k++) { 
gotoxy(posx-k, posy); 
putch('-'); 
gotoxy(posx+k, posy); 
putch('-'); 
} 
gotoxy(posx, posy); 
if(towers[i][j]) 
printf("%d", towers[i][j]); 
else 

putch('|'); 
} 
} 
} 



void move(uint s1, uint dst) 
{ 
int i, is, id; 

for(i = NUMB_OF_ELEM-1; i >= 0; i--) { 
if(towers[i][s1]) {

break; 
} 
}

}

break; 

} 
} 

return (towers[is][s1] == p1)

}

I can't see that exact line, can you point me exact code you have troubles with?
