WRITE FUNCTION PROTOTYPES for the following functions. The functions are described below on page 2. (Just write the prototypes) When necessary, use the variables declared below in maino. mm 1.) showMenu m2.) getChoice 3.) calcResult m.) showResult 5.) getInfo mm.) showName 7.) calcSquare 8.) ispositive int main { USE THESE VARIABLES, when needed, to write function prototypes (#1 - #8) double num1 = 1.5; double num2 = 2.5; char choice; double result; string firstName; string LastName; char initial; bool is pos; Also, use the variables to answer questions #9 - #15. NOTE: You can use the same variable in different questions. (1 point eachel Write the FUNCTION DEFINITIONS for the functions described in #1 - #8. Include the first line of the function and body for each definition. 9.) (1 pt.) Write a complete function definition for the showMenu function. (This function should match the prototype in #1). Return type: No value is returned. Parameters: No arguments are passed to the function. Output: A. Multiply a number by 2. Divide a number by 2. This is all of the output from the function. B. +# wrong on this page

Answer 1

1.)

• showMenu() funciton takes no argument and returns no values.
• It's prototype will be:

void showMenu();

2.)

• getChoice() funciton takes no argument and returns a character
• it's prototype will be:

char getChoice();

3.)

• calcResult() will take one double value, one character argument and return a double value.
• it's prototype will be:

double calcResult(double num1,char choice);

4.)

• show result will take a double value as argument and return none
• it's prototype will be:

void showResult(double result)

5.)

• get info will take reference to two string variables and one character variable as arguments and reutrn none.
• it's prototype will be:

void getInfo(string& firstname, string& lastname, char& initial);

6.)

• showName() will take two string arguments and one character argument , and returns none

void showName(string firstname, string lastname, char initial);

7.)

• calcSquare will take one double argument and return a double value
• it's protoype will be:

double calcSquare(double num1);

8.)

• isPositive will take a double argument and return a boolean value.
• it's prototype will be:

bool isPositive(double num1);

9.)

• showMenu() function takes no argument and returns no value. It must display the menu given in the question.
• it's function definition is:

void showMenu(){

cout<<"A.) Multiply a number by 2\n";

cout<<"B.) Divide a number by 2\n";

}
