Please provide the function or module header in  in c++ code for each of the following.  Include comments that describe the parameters and return values (if a value is returned).  Do not define the function, just give the header or prototype and comments.  Be sure to indicate if the parameters need to be passed by reference. 1. Swaps two reals. 2. Calculates and returns the sales tax of 8.25 given the price and the amount of the tax rate (both as reals). 3. Returns the concatenation of two strings. 4. Performs a search of a string for a character and returns true if the character is found and false otherwise. Expert Solution arrow_forward Swaps two reals void swap(int&,int&);//used to swap two integers.parameters are  passed by reference arrow_forward Calculates and returns the sales tax of 8.25 given the price and the amount of the tax rate float calculate(float,float);//returns the sales tax of 8.25 given the price and the amount of the tax rate arrow_forward Returns the concatenation of two strings. string combine(string ,string );//returns the  concatenated string of given strings arrow_forward Performs a search of a string for a character and returns true if the character is found else false bool find(string ,char );//checks for the given character in the string  and returns true if string have the given character otherwise false.

Please circle True or False for each of the following statements. C++ Local variables used in a function are defined in the parameter list of that functions definition.    TRUE  FALSE

The parameters passed to function are .called formal parameters True O Fales O

Write a function named product that takes two int parameters and returns the product of those two integers. Here is an example: int n = product(7, 5); // n is 35 We are providing a test framework that, if you wish, you may use with a compiler to test your function. What you will submit as your answer to this problem is only the product function. Do not submit things like the #include lines or a main routine. If we take the code you write in the space below and insert it into the program, the resulting program must build without compilation errors (mere warnings are allowed). You do not need to write comments in the code; we will not look at any comments. Here is the test framework that you may copy and paste into a C++ source file. For your own testing purposes, you might add additional tests in the main routine, although you won't be turning them in, of course. #include <iostream> #include <cassert> using namespace std; // SUBMIT AS YOUR ANSWER ONLY THE CODE BETWEEN THIS…

Local variables are known only to the function in which they are declared. Local variables are invisible outside the function in which they are declared. Whether True or False 11. It is possible for any function to return numerous values. Any function type may return multiple values. That's true, right?
