1. c++ postfix program help needed
I have already completed the first part reading and calculating result of postfix value
below is my code
http://puu.sh/oW918/a7ce52fcab.txt
and I just need help updating it so it does the following
Solution
http://puu.sh/oW918/a7ce52fcab.txt
url path program not identified. i am writing the new code in given output
#include <iostream>
#include <conio.h>
#include <string.h>
using namespace std;
struct node
{
int data;
node *next;
}*p = NULL, *top = NULL, *save = NULL, *ptr;
void push(int x)
{
p = new node;
p->data = x;
p->next = NULL;
if (top == NULL)
{
top = p;
}
else
{

2. save = top;
top = p;
p->next = save;
}
}
char pop()
{
if (top == NULL)
{
cout<<"underflow!!";
}
else
{
ptr = top;
top = top->next;
return(ptr->data);
delete ptr;
}
}
int main()
{
char x[30];
int a, b;
cout<<"enter the balanced expression ";
cin>>x;
for (int i = 0; i < strlen(x); i++)
{
if (x[i] >= 48 && x[i] <= 57)
push(x[i]-'0');
else if (x[i] >= 42 && x[i] <= 47)
{
a=pop();
b=pop();
switch(x[i])
{
case '+':
push(a+b);
break;
case '-':
push(a-b);
break;
case '*':
push(a*b);
break;
case '/':
push(a/b);

3. break;
}
}
}
cout<<"ans is "<<pop()<<endl;
getch();
}
