Question

Can some help me with a C++ program in Visual Basic?

Answer 1

In this assignment, you will write a program that:

Calculates the fewest number of coins required to dispense change from a vending machine.
Indicates the numbers of quarters, dimes, nickels, and pennies dispensed from the vending machine.
Creates a control table naming each control on the interface and identifying the key events.
Creates a data table identifying the variables.

Save your program as Dispense.cpp.

Answer 2

This type of problem screams for modulo arithmetic so let's make some variables first. I am going to set the change equal to 67 cents and initialize the counts to 0.

change = 67
num_coins = 0
num_quarters =0
num_dimes = 0
num_nickels = 0
num_pennies = 0

num_quarters += change // 25 <-- This integer division adds 2 to num_quarters
change -= 25 * num_quarters <-- update change left to give out to 17
num_dimes += change // 10
change -= 10 * num_dimes
num_nickels += change // 5
change -= 5 * num_nickels
num_pennies += change

num_coins = num_quarters + num_dimes + num_nickels + num_pennies

Answer 3

Okay so that being said my ending of the program should look something like this then.

private: System::Void btnDispense_Click(System::Object^ sender, System::EventArgs^ e) {

double amount;

int q, d, n, p; // Variables to hold calculations



//parse textbox to get number

amount = Convert::ToDouble(txtInput->Text);



// Convert to number of pennies to avoid precision errors

amount = amount * 100;



// check quarters

q = amount/25; // Number of quarters

txtQuarters->Text = Convert::ToString(q); // Display on Screen

amount = amount-(q*25); // Amount after quarters taken out

//THEN DIMES, NICKELS, AND…

//check pennies

p = amount/1; // Number of pennies

txtPennies->Text = Convert::ToString(p); // Display on Screen

amount = amount-(p*1); // Amount after pennies taken out. SHOULD BE 0





// return 0;

}

Answer 4

looks like it would work

Answer 5

Okay thanks.
