How to solve this in C++?

1. Consider the following function prototypes: (30) int funci (int, double); double func2 (string, int, double); char func3 (int, int, double, char); string join (string, string); Answer the following questions: a. How many parameters does the function funcl have? What is the type of the function funci? b. How many parameters does function func2 have? What is the type of function func2? C. How many parameters does function func3 have? What is the type of function func3? d. How many parameters does function join have? What is the type of function join? e. How many actual parameters are needed to call the function funci? What is the type of each actual parameter, and in what order should you use these parameters in a call to the function funci? f. Write a C++ statement that prints the value returned by the function funcl with the actual parameters 3 and 8.5. g. Write a C++ statement that prints the value returned by function join with the actual parameters "John" and "Project Manager", respectively. h. Write a C++ statement that prints the next character returned by function func3. (Use your own actual parameters.)
