The reset circuit used on the four 3-bit counters analyzed in this activity reset the counts to zero (000). it makes sense for the up-counters to start at zero (000), but the down-counters should start at seven (111). what would you need to change so that the 3-bit binary down counter with j/k flip-flops you just created would reset to seven (111)?

Requirement types discussed during software development include functional and color scheme nonfunctional and code style constraint and nonfunctional fashionable and functional.

Write a program that reads a set of floating-point values. ask the user to enter the values, then print • the average of the values. • the smallest of the values. • the largest of the values. • the range, that is the difference between the smallest and largest. of course, you may only prompt for the values once.
