A college course may have one or more scheduled sections, or may not have a scheduled section. Attributes of Course include courseID, courseName, and units. Attributes of Section include sectionNbr and semester. The value of sectionNbr is an integer, which distinguished one section from another for the same course, but does not uniquely identify a section. There is an operation called findNumSections, which finds the number of sections offered for a given course in a given semester.

xpress the negative value - 22 as a 2's complement integer, using eight bits. Repeat it for 16 bits and 32 bits. What does this illustrate with respect to the properties of sign extension as they pertain to 2's complement representation?  8 bit The 8-bit binary representation of 22 is 00010110. So, - 22 in 2's complement form is (NOT (00010110) + 1) = (11101001 + 1) = 11101010
