Character place

[turke]

How can I take characters from their place and put them into variables?
Example:
User input : 5+9+7
a=5(1st)
b=+(2nd)
...

I hope you get what I mean =P

-EDIT-
Oh yeah, my friend said something about using "ordinal"? =S

Well, you could just use getline() and put the input into the string, then you can just iterate through the characters to get each part.

hmm...a simple example perhaps? =D

Well, the example would basically be doing it for you because it's so simple XD.

and possibly

hmm...
I tried something like this...
It should calculate equation of type a(+/-)b(+/-)c...

#include <iostream>
#include <string>
using namespace std;

int main ()
{
   string str;
   cin >> str;
  
  int d=0;
  int e=0;
  int a = str.at(1);
  int b = str.at(3);
  int c = str.at(5);
  char sum1 = str.at(2);
  char sum2 = str.at(4);
  
  if(sum1 == '+')
  d=a+b;
  else if(sum1 == '-')
  d=a-b;
   
  if(sum2 == '+')
  e=d+c;
  else if(sum2 == '-')
  e=d-c;
   
  cout << e << endl;
  
  system("PAUSE");
    return 0;
}

It just breaks down... =( xP

indices start from 0, not from 1.
notice that str.at will return a character eg: '5', not the number 5.

By the way, isn't easier something like this?

int a,b,c;
char sum1,sum2;
cin >> a >> sum1 >> b >> sum2 >> c;

[turke]

Yes it is but I wanted to do it using str.at...
