Write a program that prompts the user to enter two positive integers A and B where A > B and then displays the sum of every other element starting from A and up to but not including B. For example, if the user enters 5 and 12, then your program should print the sum of 5, 7, 9, and 11 which is equal to 32. Your input and output formats must match with the one shown below. Example Input: Enter the first number: 5 Enter the second number: 12 Exemple output: The sum of every other number between 5 and 12 is 32. Paste your code in the box below.

3. (a) A 3" x ½" strip of annealed C26000 brass (70Cu-30Zn) is cut into nine 6" lengths. Each strip is put through a rolling mill with the distance between the rolls set from 0.250" down to 0.050" in intervals of 0.025". (Thus the first sample is rolled at 0.250", the second at 0.225", and so on). The hardness of each sample is then measured using a Rockwell superficial tester (similar to regular Rockwell except lighter loads are used, thus better for thinner materials). Sketch the graph of hardness vs cold work. Explain the nature of the graph. (b) The sample that was rolled to 0.100" is now cut into seven (7) approximately equal pieces. Each piece is annealed for 10 minutes in a vacuum furnace. The temperature of the furnace is varied from 100°C to 700°C in intervals of 100°C. (Each piece is annealed at one temperature). After annealing the pieces are water quenched, dried and then their hardness measured using the same hardness tester. Sketch the graph of hardness vs annealing temperature and explain the nature of the graph.
