what's wrong while statement

Code:

---

#include <iostream.h>
#include <stdlib.h>

int main()
{
      //basic devines formila int;s
      int x = 1;
      int y = 1;
      int answer = 1;
      int tt = 1;
      //end
      //work process
      while (x < 525){  //wait till x = 525
            int answer = x * y + answer + 3;
            int x = x + tt ;  //x is x +1 (tt)
            int y = y + tt ;  //y is y +1 (tt)
            }
      cout <<"answer is = "<<answer<< "got it";    //print the answer
      system("PAUSE");
      return 0;
}

---

you are declaring a local 'x' within that while loop.

you are also declaring a local "answer" so your output will always be 1 (the value of answer local to main). remove the "int"s within that while loop and you should be fine.

I am not too sure what you want but probably u can replace the part of your code with the loop with this

Code:

---

while (x < 525) {
  answer += (x++ * y++) + 3;
}

x++ & y++ represents your increment after usage. Your loop will execute 524 times only.
