ECE2801 HW #1-- C programming and Binary Number Representations (DUE 9/4/09 At the BEGINNING of class) To assure proper grading and return, be sure to attach the HW cover sheet! Always review any reading assignments before attempting the homework problems. Show all of your work. Clearly indicate results (underline, circle or box) Always write neatly. The grader can not be expected to GUESS what you meant to do! Problem #1 (20 pts) a) How many times would each loop actually iterate on the MSP430C449? Explain you reasoning. unsigned int cnt= 1; while (cnt > 0) cnt++; unsigned int j, P, Q, first=0, last = 10,000; for (j=first; j < last; j++) { Q = last-j; P = somefunc(Q); } What is the value of Q in the first loop, in the final loop? b) Write a complete C program that will calculate the mean, the mean of the squares and the square of the mean of 10 real numbers. Your main should assign the values of the numbers to a globally defined array and then call 3 functions (you may assign static numbers to your array for this HW. The MSP430 doesn't
