Thread: calculate the factorial and display in two column.

1. Calculate the factorial for values 1-20 and display the results Display the results in two columns. Left column 1 – 10 and the right column 11 – 20.
   Here is my code, can someone help me.
   
   
   Code:

   void FactorialNumberFor1To20(int intIndex)
   {
       int intFactorial = 0;
       int intArraySize[19];
   
           intFactorial = intArraySize[19];
           for (intIndex = intArraySize[19]; intIndex > 1; intIndex -= 1)
           {
               intFactorial = intFactorial * (intIndex - 1);
               intArraySize[intIndex] = intFactorial;
           }
   
           cout << intArraySize[intIndex] << setw(40) << " " << intArraySize[intIndex + 10];
   }

I might suggest starting simpler and writing a function that calculates the factorial for a given integer.

Code:

int factorial(int const x)
{
 // implement
}

Then you can begin composing the rest of your programming logic in terms of this function.

I don't have any idea about how to display the result in two columns after I calculated the factorial.
