Question

Visual Basic Programming

Step 1-2 not important, it's just file naming.

3. Form contains nine Labels, one TextBox, and three Button controls. You use labels to let user know what to enter and what will be displayed; TextBoxes to input a number between 1 and 99. Buttons to Calculate change. Clear Input and Exit program. See below Form Layout with Controls for more details 4. Declare variables to store the entered value in TextBox, and what will be displayed in quarters, dimes, nickels and pennies Labels. See below Form. These variables are Integer type. 5. Use integer division operator () to calculate number of coins. o Integer division examples: 19 15 is 3, 22110 is 2, 1513 is 5,415 is 0. 6. You will use MOD function to calculate the remainders o MOD examples: 19 MOD 5 is 4, 22 MOD 10 is 2, 15 MOD 5 is o (no remainder), 4 MOD 5 is 4. 7. Items to note: 8. variables names must follow the conventions and rules explained in this week's slides and must have proper data type for the values that will be stored in them. i.e., variable name to store TextBox value should be intCents. 9. Appearance of the form is very important: Make sure that your design is clean; Spelling is important. 10. Text property of controls must use the text shown in below Form. 11. Clear Input button, clears TextBox and Labels that display the output. 12. Exit button, closes the Form. 13. You will write the code for the three buttons. 14. Avoid double-clicking on TextBox and Label Controls to create unnecessary code. 15. Run the program, enter values in the TextBox then click Calculate button, you should see the break down of the entered number in Quarters, dimes, nickels and pennies in their corresponding labels. See below screenshot for complete program 16. To save the project, from File, select Save All Enter a value between 1-99 Quarters Dimes Nickels Pennies Calculate Clear Exit Enter a value between 1-99 47 Quarters Dimes Nickels 0 Pennies Calculate Clear Exit

Form design Screenshot:

Forml.cs* 1.Cs T Forml.cs [Design)" orm.cs IDesignX + X Form Enter a Value between 1-99 Quarters Dimes Nickels Pennies Calculate Ö Clear Exit

Program:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace ChangeCalculator
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
//declaring variables for quarters, dimes, nickels and pennies
int quarters, dimes, nickels, pennies,leftover;
//converting text to integer
leftover = Convert.ToInt32(textBox1.Text);
  
//code to calculate Quarters
quarters = leftover / 25;
leftover = leftover Mod 25;
//displaying number of quarters in a textbox
tquarters.Text = quarters.ToString();

//code to calculate dimes
dimes = leftover / 10;
leftover = leftover Mod 10;
//displaying number of dimes in a textbox
tdimes.Text = dimes.ToString();

//code to calculate nickels
nickels = leftover / 5;
leftover = leftover Mod 5;
//displaying number of nickels in a textbox
tnickels.Text = nickels.ToString();

//code to calculate pennies
pennies = leftover;
//displaying number of pennies in a textbox
tpennies.Text = pennies.ToString();

}

  

//code for clear Button(clears all fields on button click)
private void clear_btn(object sender, EventArgs e)
{
textBox1.Clear();
tquarters.Clear();
tdimes.Clear();
tnickels.Clear();
tpennies.Clear();
}

//code for exit button(Exits the entire form)
private void exit_btn(object sender, EventArgs e)
{
this.Close();
}

}

}

Output:

Screenshot of output

Form1 Enter a Value between 1-99 47 Quarters 2 Dimes Nicikd Pennies 2 Calculate Clear Exit

Screenshot for clear button:

Form1 Enter a Value between 1-99 Quarters Dimes Pennies Calculate Clear Exit
