Write a shell script for the calculator program, your script has to display the menu showing the selection to process. Take two inputs from the user to perform the choice of operation on Addition, Subtraction, Multiplication, Division and Modulus.

1. Identify the following parameters to complete the specification above. Input parameters? Output parameters? Constant parameters? 2. Attach the input and output of a successful execution of your program below (Hint:Use the snipping tool to take screenshots):

A software receives data from a file named inputFile.dat and outputs the results to a file called outFile.dat after doing certain computations. Respond to the following questions:   a. What is the content of the file inputFile.dat after the application runs?   b. What are the contents of the file outFile. dat after the programme executes if this file was empty before the programme executed?   c. What are the contents of the file outFile. dat after the programme executes if this file held 100 numbers before the programme executed?   d. What would happen if the file outFile.dat did not exist when the programme was run?

If I have a button attached to port 4 of my Grove Shield, which is attached to my Arduino Uno, which function call can I use to get the state of that button using Python? Assume that the engi1020.arduino module has been correctly imported. read(digital, 4) ) digital_read(4) ) digital_write(4, 1) O analog_read(4)

In Python IDLE   Will the following code run?  Why or why not?  Assume that the blocks of code are correctly formed and will run if correctly called and that this is the entire program. def fct():    block1   def main():    block2    fct()    block3

i got this error when i run could you help me please thank you  /unix_hw/output/unix_hw$ gcc helloworld.c -o output/helloworld/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/9/../../../x86_64-linux-gnu/Scrt1.o: in function `_start':(.text+0x24): undefined reference to `main'collect2: error: ld returned 1 exit status

This is a c language question I do not know how how to make main.c and stock.c along with reporting, buying, and selling functions and their definitions. I hve also attached a samole binary file. (p.s: it is unreadable) Here’s the question: This program implements the buying and selling of stocks. It starts by printing a welcome message Welcome to mystocks.com Then a main menu of choices for the user is output. Reporting, buying or selling? (0=quit, 1=report, 2=buy, 3=sell): The program ends with a goodbye message. Thank you for trading with mystocks.com Use doubly linked list of stock_t structures. stock_t structure looks like: #define MAX_TICKER_LENGTH 6 typedef struct stock_t {   char ticker[MAX_TICKER_LENGTH];   date_t date; // date bought   int numShares;   double pricePerShare; } stock_t; date_t structure looks like: typedef struct date_t {   int month, day, year; } date_t; Create the following files in a directory: date.h: contains the above date_t structure • stock.h…

Which of the follow are true about variables? Choose all that apply. variables are names bound to values in memory variables are automatically assigned a default value of their data type after declaration variables are assigned an initial value and then cannot be reassigned variables can be used to store intermediate results of computations variable names are governed by the rules of identifiers variables with the same name but different values cannot exist in a program
