Good interview Questions

Having array[99] and i am trying to assigning the 1 to 100 numerical values in the array in any manner and no duplicate values in the array there will be one missing number . Find the missing number .

Give the solution in C or C++

Code:

---

DWORD MissingNumber = 5050;

for(int x = 0;x<99;x++) MissingNumber -= array[x];

---

Missing number will now contain the missing number.

That's an awesome solution. Wouldn't have come up with that myself.
