Question

 Modify the postfix program below to handle both subtraction and division:

Sample input:  ./a.out 4 10 - 6 x 12 /  Sample output:  -3

#include <iostream> #include <cstring> #include "stack.cpp" using namespace std;  int main(int argc, char *argv[]) {         char *a = argv[1];         int i, div, N = strlen(a);         stack<int> save(N);         for(i = 0; i<N; i++)         {                 if(a[i] == '+')                         save.push(save.pop() + save.pop());                 if(a[i] == '*')                         save.push(save.pop() * save.pop());                 if(a[i] == '-')                         save.push((-1)*save.pop() + save.pop());                 if(a[i] == '/')                 {                         div = save.pop();                         save.push(save.pop() / div);                 }                 if((a[i] >= '0') && (a[i] <= '9'))                         save.push(a[i] -'0');                 //while ((a[i] >= '0') && (a[i] <= '9'))                 //      save.push(10*save.pop() + (a[i++]-'0'));         }         cout << save.pop() <<endl; } 

Explanation / Answer

`int main(int argc, char *argv[]) {` char *a = argv[1]; int i, div, N = strlen(a); stack save(N); cout > a; for(i = 0; i= '0') && (a[i] = '0') && (a[i]
