Question

Please do the following:

Write a test function of your choice
Create any for or while loop that works in your main function
Create an if-else statement that works in your main function. Make sure the if condition is true
Create a block of codeLinks to an external site. ({<statement(s)>}) in your main function. See my example
Before (outside) of your main program, declare a const double variable like, const double pi = 3.14159265359;
Try to access it by printing in all your code blocks (your main, function, loop, if-else and block of code)
Define and initialize any variable at the top of your main function and try to access it by printing in the, function, loop, if-else and block of code
Define and initialize any variable inside your function and try to access it by printing in your, main, loop, if-else and block of code
Define and initialize any variable inside your loop and try to access it by printing in your, main, function, if-else and block of code
Define and initialize any variable inside your if-else and try to access it by printing in your, main, function, loop and block of code
Define and initialize any variable inside your code block and try to access it by printing in your, main, function, loop and if-else
Based on your observations verify features in scope of a variableLinks to an external site.
Based on your experience and read above please match answers to last 4 items on left side.

Match the entities on left with the entities on right. Left entrees may associate more than one matching answer though they set only the most appropriate answer. If this is the case, please match the most appropriate answer.

The variable, pi
The variable in main
The variable in the function
The variable in the loop
The variable in if-else
The variable in the code block
Where would be the best palace to declare a
constant variable you need access throughout your
program?
Where would be the best palace to declare a
variable you need only within your function?
Where would be the best palace to declare a
variable you need only within your loop?
What is the conclusion?
[Choose ]
[Choose ]
is accessible in the, main, loop, if-else, function, and code block
is accessible in anywhere in the program
A variable is only accessible(visible) within the scope of its declaration.
Outside the main (the outermost scope, the global scope)
is not accessible in the main program
Inside the loop (a local scope).
Inside the function (a local scope).
