Question

C++ Fill in the blanks please

You are required to fill in the blanks in this program. Consider that: -In main, the variables price and quantity were given the names of p (double) and q (int), respectively. -In the getData function, the parameters associated with the main variables p and q were called pp and pq, respectively.

// Prototype: Do not include the names // of the variables in the prototype

void getData (FILLTHEBLANK , FILLTHEBLANK);

int main ()
{
double p; // p = price of the item
int q; // q = number of articles
double total;

// Call of the function getData - complete
// Remember that p and q want to pass as redeference,
// pointers mode.

getData (FILLTHEBLANK , FILLTHEBLANK);

// Complete the formula that multiplies price and quantity.

total = FILLINTHEBLANK * FILLINTHEBLANK;

cout << "Total to pay =" << total << "\ n \ n";

return 0;

}

// Heading of the function - fill in the data type of the parameters. Note that the parameter names must be pp and pq.

void getData (FILLTHEBLANK, FILLTHEBLANK)

{
cout << "Enter the price of the item:";
cin >> FILLTHEBLANK;

// This is where the price validation would go. Code not included.

cout << "Enter the number of items purchased:";

cin >> FILLTHEBLANK;

// This is where the quantity validation would go. Code no included. }

Answer 1

#include <iostream>
using namespace std;
// Prototype: Do not include the names // of the variables in the prototype

void getData (double& , int&);

int main ()
{
double p; // p = price of the item
int q; // q = number of articles
double total;

// Call of the function getData - complete
// Remember that p and q want to pass as redeference,
// pointers mode.

getData (p, q);

// Complete the formula that multiplies price and quantity.

total = p * q;

cout << "Total to pay =" << total << "\n\n";

return 0;

}

// Heading of the function - fill in the data type of the parameters. Note that the parameter names must be pp and pq.

void getData (double &price, int &quantity)

{
cout << "Enter the price of the item:";
cin >> price;

// This is where the price validation would go. Code not included.

cout << "Enter the number of items purchased:";

cin >> quantity;

// This is where the quantity validation would go. Code no included.
}

Output:

Enter the price of the item:34.12 Enter the number of items purchased: 5 Total to pay =170.6
