Write a program to test your functions as follows: • Obtain a random number seed from the command line of your program • Initialize an array p of 8 unsigned char with random numbers from 0 to 255 • Initialize a separate unsigned character byte0 with a random number. • Print the values in the array p as well as the value for byte0. o Print the values in decimal format as well as binary format (use macros defined below) • Call setlsbs() using p and byte0 as parameters • After the call to setlsbs() is completed, print the modified values of the array p. o Print the values in decimal format as well as binary format (use macros defined below) • Use the modified array p as a parameter to getlsbs() • Print the return value of the call to getlsbs(). The returned value should match the original value for byte0 o Print the value in decimal format as well as binary format (use macros defined below)

Figure 1 Test Apparatus Cross Section A backyard scientist was working on a design for a novel heat exchanger, and was testing the properties of a coolant plpe he designed. The test pipe was cast in a bronzal alloy the scientist was investigating. The scientist th a Poisson's ratio of 0.34. After casting. the pipe was polished inside and out, and was placed in a test apparatus as shown in Figure 1 . One end of the pipe was foxed to a plate as shown in the above diagram, and the other end was subjected to a to measurably deform during the test.
