1. Draw a console window and show the expected output as precisely as possible.

1. 

int add(int num1, int num2);
int square(int num);

int main()
{
   int num1 = 10;
   int num2 = 15;
   int result = 0;
   
   result = add(square(num1), num2);
   cout << result << endl;
   
   return 0;
}// end of main

int add(int a, int b)
{
   int sum = a + b;
   return sum;
}// end of add

int square(int num)
{
	return num * num;
}// end of square

2.

double computeDiscount(int num, double price, double rate);
double computeTax(double base);

int main()
{
   double pricePerWidget = 19.99;
   int numWidgets = 4;
   const double CLEARANCE_DISCOUNT = 0.2;
   double basePrice = 0.0;
   double finalPrice = 0.0;
   double discount = 0.0;
   
   basePrice = numWidgets * pricePerWidget;
   discount = computeDiscount(numWidgets, pricePerWidget, CLEARANCE_DISCOUNT);
   finalPrice = basePrice - discount;
   finalPrice = finalPrice + computeTax(finalPrice);
   
   cout << finalPrice << endl;
   
   return 0;
}// end of main

double computeDiscount(int num, double price, double rate)
{
	double base = num * price;
	return rate * base;
}// end of computeDiscount

double computeTax(double base)
{
	return base * 0.06;
}// end of computeTax
