Below I have provided the solution to the given C program.

2. The C program in Figure 1 is to show the elapsed time on LCD display in seconds. The program uses a Ticker with a period of 10ms to control system timing. (1) Modify the program such that it uses a time base of 1 ms to drive the clock. (2) Modify the program in such a way displays elapsed time in hours, minutes and seconds.

The answer needs both a C++ and a Python code and the source code for the C++ is a picture attached Design a menu with appropriate user interactions and checks for valid entry. Use C++ to successfully complete this criterion. Your simple program will need a menu that can validate user input and is easy to use. It needs to include options for the display of a multiplication table, doubling a value, and exiting the program. If either of the first two options are selected, then users need to be prompted to input a numeric value. The menu should be displayed using a loop, where the user can choose to exit the program only by selecting option 3. Any user input other than 1, 2, or 3 should result in an error message that returns the user to the menu. An example menu might look like the following:1: Display a Multiplication Table 2: Double a Value 3: Exit Enter your selection as a number 1, 2, or 3. Create code that prints a multiplication table for a given numeric value. Both C++ and…

Create a C program: Lisa is having a hard time in locating Quadrants in the coordinate plane. Help her familiarize with the quadrant location by creating a program that would accept a coordinate point (x and y ) and determine in which quadrant does this point lies. Input: Input an integer value representing the x and y axis location, and must be a whole number. Output: The first and second lines will contain a message prompt to input the x and y coordinates of a point. The last line will display the quadrat number the point lies.

If you have trouble reading the picture please let me know. 8. (a) Write behavioral Verilog code for a module called “Sort2” (pictured below) with three inputs s, a, b and two outputs x, y. The module’s function is also described below; in the function table, a “–” represents a don’t care. Also the function table has s, a as inputs, but the outputs x, y are expressed in terms of the third input b. In words, the “function table” to the left translates to the following: When s = 0, the smallest value among a and b goes to x and the other value goes to y. When s = 1, the largest value among a and b goes to x and the other value goes to y. (b) Structurally connect copies (or instantiations) of the module Sort2 to construct the module Bitonic with four inputs a0,a1,a2,a3 and four outputs z0,z1,z2,z3 shown below; each box in the figure below represents an instantiation of Sort2. Further, the inputs and outputs of the instantiations are located as in the figure above; namely, input to…

It is a single question with parts. Please consider this. C++ You are required to develop a complete C++ program to help small electric factory in managing the order and producing the product order report. Your program should produce the output as in the sample execution as shown in Figure 1, in which the values in bold are input by the user. You must read the instruction carefully whether the input entered should be in main function or in other function. Your program should have 5 functions as follows: Function 1: Write a function named readData. This is a non-returning function. It takes the number of regular order, new order and cancel order as input parameters. The function should ask the user to enter the number of regular order, new order and cancelled order. It sends all the values entered by the user in (c) back to the calling module through the use of reference parameters. Function 2: Write a function named printLevel…
