Use conceptualization and extract out the appropriate data structure, concepts, and paradigms to solve this problem. Develop pseudocode by writing in plain text the sequence for which the extracted data structure, concepts, and paradigms should be utilized to solve this problem. Conduct the two aforementioned procedures appropriately. Using a C++ editor of your choice, write ONE C++ program that includes all of the following:

Builds a syntactically correct void function.

Builds a syntactically correct value-returning function.

Using either a void or value-returning function, builds a syntactically correct function that passes arguments by value.

Using either a void or value-returning function, builds a syntactically correct function that passes arguments by reference.

Build a function that also consists of a function prototype as part of its call and definition.
