Lets consider the following program:

#include iostream

include

using namespace std;

int addition (int, int );

int subtraction (int , int );

void directions();

void printResult(int , int , int , string);

int main ()

{

int x,y,r;

directions();

cout << "Please enter the first integer: "<<;

cin >> x;

cout << "Please enter the second integer: ";

cin >> y;

r = addition(x,y);

printResult(x,y,r,"+");

r = subtraction(x,y);

printResult(x,y,r,"-");

system("pause");

return 0;

}

int addition (int a, int b)

{

int r;

r=a+b;

return r;

}

int subtraction (int a, int b)

{

int r;

r=a-b;

return r;

}

void directions()

{

cout << ********************************************************" << endl

<< "Hello!" << endl

<< "This Program asks the user for two integers, then prints the sum and difference" << endl

<< "******************************************************" << endl << endl;

}

void printResult(int a, int b, int result, string operation)

{

cout << a << " " << operation << " " << b << " = " << result << endl;

}

1) Give the prototype of each function.

2) Give the arguments of each function.

3) give the parameters of each function.
