Please Help Me With This Code Of Implementing Stacks

i want to implement multiple stacks using arrays..I am able to create ,insert and print them but not poping an element form any of the stack..This is what i have

Code:

#include<stdio.h>
#include<conio.h>
int top[5];
int bot[5];


void main()
{
int a[50]={0} ;
int length,num;
int ch;
int temp,x,st_no,st_no1;
int b,i,j,k;
clrscr();
printf("Enter the length of the total stack: ");
scanf("%d",&length);
printf("\nEnter the number of stacks: ");
scanf("%d",&num);
//divinding the arrays into stacks
b=(length)/(num);
top[0]=0;
bot[0]=0;
for(i=1;i<num;i++)
  {
    top[i]=top[i-1]+b;
    bot[i]=bot[i-1]+b;
  }
do
   {
    printf("\n1.PUSH 2.POP 3.PRINT 4.EXIT \n");
    printf("Enter the choice: ");
    scanf("%d",&ch);
    switch(ch)
      {
       case 1:
	printf("Enter the stack number: ");
	scanf("%d",&st_no);
	if(top[st_no-1]==bot[st_no] || top[st_no-1]==length)
	printf("\n\n\n!!THE %d STACK IS FULL\n",st_no);
	else
	{
	  printf("ENTER THE ELEMENT TO BE PUSHED");
	  scanf("%d",&x);
	  a[top[st_no-1]]=x;
	 top[st_no-1]=top[st_no-1]+1;
	}


	  break;
	//-------------------------------------------------------
	case 2:
		printf("\nENTER THE STACK NUMBER");
		scanf("%d",&st_no1);
		printf("\nThe stack you have choosen is %d",st_no1-1);
		printf("-----%d-----",a[top[(st_no-1)]]);
		if(top[st_no-1]==bot[st_no-1])
		printf("\n!STACK EMPTY!\n");
		else
		{

		  printf("\nDELETED ELMENT IS: %d\n",a[top[st_no1-1]]);
		  top[st_no1-1]=top[st_no1-1]-1;
	       }

	     break;
       //----------------------------------------------------------
	case 3:
	   k=0;
	   for(i=0;i<num;i++)
	    {
	    printf("\nThe elements in stack %d are: ",i+1);

		       for(j=0;j<b;j++)
		 {
		  printf("%d->",a[i+j+k]);
		  }
	       k=k+b-1;
	     }


	    break;
	}
    }
    while(ch<4);
    getch();

}

more info? (expected result when you pop, actual result given by the code)

when i push an item in to stack 1 i get the contents of the stack as item-0-0 etc....
but when i pop the element my top and bottom(top,bot) of the stack are moving but i am unable to display the stack after poping....

Code:

int main()

Also make sure that main() returns 0.

Are you sure you want two variables called st_no and st_no1, it looks like you are getting confused as to which one to use.
