// for the below problems, follow this process:
// 1) figure out the function inputs and outputs
// 2) from those, determine how many value and reference parameters you need, and if your function 
//    will have a return value or be void
// 3) write the header
// 4) then work on the body to actually do the work


// define a function that takes one integer in, gets another integer from the user,
//  and passes back the sum and difference of those two numbers.



// define a function large_and_small that:
// 1) gets numbers from the user until the user types -1
// 2) passes back the largest and smallest of those numbers

	// print the values you got from that function here



	// call your large_and_small function, using appropriate local variables to pass data in and out


	// print the values you got from that function here
