Define a function PrintValue() that takes two integer parameters and outputs the sum of all integers starting with the first and ending with the second parameter, followed by a newline. The function does not return any value.

Ex: If the input is 1 4, then the output is:

10

Note: Assume the first integer parameter is less than the second.

Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7: 

42 seconds

Define a function CalcPyramidVolume() with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. CalcPyramidVolume() calls the given CalcBaseArea() function in the calculation. 

Relevant geometry equations: 

Volume = base area x height x 1/3 

(Watch out for integer division).
