Please provide specific illustrations of how calls and returns fit within the larger scheme.

A brief explanation of call by value versus call by reference would be helpful. Sincerely,

When is it OK to use union compatibility between two select statements that utilize the same table?

Please write the code in C language thank you

The "type" keyword alone is inadequate when declaring a variable. The data type and other characteristics of a variable serve as identifiers. How to use this idea to describe any given variable is the next logical step.

Please complete the exercise as instructed and do not use global variables. Please follow the guidelines of what the solution cannot use provided in the second picture. Thank you!

Create the following variables that can be used to store values. Use the naming conventions as outlined in the Algorithms/Pseudocode Guidelines document in the course resources section of the course.      1.     test grade for student test      2.     total of all test grades added together      3.     the average for the test grades Create an assignment statement that sets the value of the variable you created to store the value of all test grades added together to zero. You may refer to Table 6.1 in Chapter 6 for examples. Create an input statement to input the value for the first test grade for the variable you created. Create an algorithm that will obtain the test grade for three students, add the test grades together, calculate the average of the test grades, and output the average. Use a count-controlled loop to create the algorithm. Use the information from your answers to questions 3, 4, and 5 in the creation of your algorithm. Also use information and examples from Chapter 6…

Why is defining functions so important when writing code?
