SImple code, need help

Hey everyone,
Just started really getting into C++ and i need a bit of help with a code:

Code:

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

#define lastQuestion 4

const int addition = 1;
const int subtraction = 2;
const int multiply = 3;
const int division = 4;

void askQuestion(int one, int two, int three, int x)
{
    int answer, input;
    
    switch (x)
    {
        case addition:
                answer = one + two;
                cout << one << " + " << two << " = ";
                break;
        case subtraction:
                answer = one - two;
                cout << one << " - " << two << " = ";
                break;
        case multiply:
                answer = one * two;
                cout << one << " * " << two << " = ";
                break;
        case division:
                answer = one / two;
                cout << one << " / " << two << " = ";
                break;      
                
    }

    cin >> input;
    
    if (input == answer)
        cout << "You are right!" << endl;
    else
        cout << "You are wrong, the right answer is " << answer << endl;
  
}

int main(int argc, char *argv[])
{
  int one[lastQuestion], two[lastQuestion],three[lastQuestion], x[lastQuestion];
  
  one[1] = 8; two[1] = 3; x[1] = addition;
  one[2] = 4; two[2] = 2; x[2] = subtraction;  
  one[3] = -3; two[3] = -3; x[3] = multiply;   
  one[4] = 15; two[2] = 5; x[2] = subtraction; 
    
  for(int i = 1; i <= lastQuestion; i++)
    askQuestion(one[i], two[i], three[i], x[i]);

  system("PAUSE");	
  return 0;
}

The program allows you to answer 3 math problems, but when I add the fourth, it skips over it. Any help is appreciated.

arrays are numbered 0 to but not includeing lastQuestion

Code:

  one[0] = 8; two[0] = 3; x[0] = addition;
  one[1] = 4; two[1] = 2; x[1] = subtraction;  
  one[2] = -3; two[2] = -3; x[2] = multiply;   
  one[3] = 15; two[3] = 5; x[3] = subtraction; 

for(int i = 0; i <  lastQuestion; i++)

one [4] has bounds 0 - 3, not 1 - 4

Thanks, I got it working.
