Thread: Problem on my base-8 converter program...

Code:

#include <stdio.h>
#include <conio.h>
#include <math.h>
#define STACKSIZE 100

typedef int Item_t;

typedef struct{
	Item_t number[STACKSIZE];
	int Top;
}Stack_t;

void InitializeStack(Stack_t *S);
int EmptyStack(Stack_t S);
int FullStack(Stack_t S);
void Push(Item_t num, Stack_t *S);
void Pop(Stack_t *S, Item_t *num);

int main()
{
	Stack_t S;
	Item_t num;

	double count=0,i;
	double c,decimal;
	int temp;


	InitializeStack(&S);

	printf("Enter a base8 number :");
	scanf("%lf",&num);

	for(i=0;i<num;i++){
		if(num<pow(10,i)){
			c=num/pow(10,i-1);
			if(c==8 || c==9)
				printf("Error!!");
			else{
				Push(c,&S);
				count++;
			}
		}
		temp=pow(10,i-1);
		num=num%temp;
	}

	printf("\n\nCount : %lf",count);

	printf("\n\nThe result of Pop: \n");

	for(i=0; i<count; i++)
	{
		Pop(&S, &c);
		putch(c);
		decimal+=c*pow(8, i);
	}

	printf("\n\nThe equivalent decimal number   : %lf\n\n", decimal);

		





return 0;
}

void InitializeStack(Stack_t *S)
{
	S->Top=0;
}

int EmptyStack(Stack_t S)
{
	return(S.Top==0);
}

int FullStack(Stack_t S)
{
	return (S.Top==STACKSIZE);
}

void Push(Item_t num, Stack_t *S)
{
	if(FullStack(*S))
		printf("\nERROR: Stack overflow!\n");
	else
	{
		S->number[S->Top]=num;
		++(S->Top);
	}
}

void Pop(Stack_t *S, Item_t *num)
{
	if(EmptyStack(*S))
		printf("\nERROR: Empty stack.\n");
	else
	{
		--(S->Top);
		*num=S->number[S->Top];
	}
}

The error occured on the num=num%temp; line... it says 'Pop' cannot convert parameter 2 from 'double*' to 'int*'...

Can anybody please help me!!!

Thanks in advance!!!
