Design a counter with an external control, x, to count the sequence (i. e., 1-2-7 and repeat) when the control is 0, and the sequence (i. e., 0-3-4-5-6 and repeat) when the control is 1. These values will be displayed on a seven-segment display like the one used in Lab 5. When the control value changes, the first clock should drive the output to the first value in the appropriate count- e. g., if the circuit has been counting the second sequence, and the control switches to 0, the first clock should drive the output to 1 (or if you have been counting multiples and the control switches to 1, the first clock pulse should make the output 1). Use any flip-flops available in the lab cabinet in your design. For input and output circuits, you may use any chips available in the lab, but you must justify your choice, both of your design and of the flip flops you use (combinational logic, decoder, or PLD). You must demonstrate your counter using your 7-segment display and any additional logic gates/devices that you need to control the circuit.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
