// Write the two functions indicated.  It is not necessary to write any 
// function prototypes.  Just write the complete functions at the top 
// of the file as indicated.

// Your functions must work for *any* input, not just for the examples 
// given in this main program.  You are welcome to add additional test
// cases.

// Note that program comments are required for full marks.


// This function (numberFacts) has three parameters and returns nothing (void).
// The first parameter is "return"ed by the function.
//    It is set to true if the third parameter is between 10 and 20 (inclusive) and false otherwise.
// The second parameter is "return"ed by the function.
//    It is set to true if the third parameter is less than 17, and false otherwise.
// The third parameter is an integer. 



// This function (arrayInfo) has three parameters and returns an integer.
// The first parameter an integer.
// The second parameter is an array of integers.
// The third parameter is an integer indicating the length of the array.
// If the third parameter (length of the array) is invalid (i.e. doesn't
// make sense), the function returns -1.
// Otherwise, this function returns the number of elements of the array 
// that are exactly divisible by the first parameter, i.e. there is no remainder
// when dividing the array element by the first parameter.
