[tinstaafl]

2 things to start with:

• In the Expenditures class your functions are using a variable(sp) that isn't defined anywhere in the functions or the class.

• You use this statement alot: else {cerr<<"Wrong Choice!!"; exit(0)};. The semi-colon goes inside the bracket:

  else 
  {
      cerr<<"Wrong Choice!!"; 
      exit(0);
  }
  

Notice how expanding the block to multi-line format makes it much easier to see the right syntax.

On a side note having a series of string arrays will eliminate all those switch blocks. For instance:

char wbdisplay(int wb)
    {char wbname[40];
    switch(wb)
    {case 1:strcpy(wbname,"Flipkart");
            break;
    case 2:strcpy(wbname,"Amazon");
            break;
    case 3:strcpy(wbname,"SnapDeal");
            break;
    case 4: strcpy(wbname,"PayTM");
            break;
    case 5: strcpy(wbname,"eBay");
            break;
    case 6: strcpy(wbname,"ShopClues");
            break;
    default:cerr<<"Wrong Choice!!"; exit(0);}
    return wbname;
    }

becomes:

string wbdisplay(int wb)
{

    if(wb < 1 || wb > 6)
    {
        cerr<<"Wrong Choice!!"; 
        exit(0);
    }
    string wbNames[6] = {"Flipkart","Amazon","SnapDeal","PayTM","eBay","ShopClues"};
    return wbNames[wb - 1];
}

Also since you're using using c++ already it makes sense to use strings instead of character arrays.

[rubberman]

Also use classes where your constructor or setter methods can set internal variables that can be accessed with a simple getter method. Add to that @tinstaafl's suggestion about array's of strings, you can do something like obj.wbdisplay(); where the wb value is stored in the object when it is constructed. Also, wbdisplay(int) should return a string and not a char just as tinstaafl showed. It would be much more efficient, and do just what you want.
