    Help using arrays and loops for math

    I am trying to construct a C++ script that will utilize an output based upon math equations. Could anyone provide a rough example of code in which I would construct a math equation with a looped array.

    For instance I would like to call 2 arrays with two different values, then I would like the program to take each value from the first array and divide by each value in the second array to see if it equals a variable, I call RATIO.

    Example:
    firstArray1 / secondArray1
    firstArray1/secondArray2
    firstArray1/secondArray3

    firstArray2/secondArray1
    firstArray2/secondArray2
    firstArray2/secondArray3 etc. etc.

    I think I will be using an IF statement -
    in that IF RATIO = firstArray/secondArray etc. then output this .... (not sure if that changes anything)

    As always, thanks for helping out someone who is clueless!

    Code:
    for ( first = 0 ; first < nFirst ; first++ ) {
  for ( second = 0 ; second < nSecond ; second++ ) {
    // do stuff with firstArray[first] and secondArray[second]
  }
}
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Sorry to be pedantic, but C++ is not a scripting language. You *write* C++ *programs*. C++ is compiled, scripts are interpreted, there's a big difference.
