Programming - Essay Example

Logic and Programming Programming A problem Analysis Chart Given information The information provided is that children below 18 Years of age should not be considered as customers for purchases.
Required Results
Processing required
Solution Alternatives
The only alternative is to use the “if” condition to test whether the age is greater than, equal to or less than 18.
2. A flowchart
3. A chart showing input, output, and processing
Year of Birth
YOB
Year Today
YT
Age
(YT-YOB)
Status
Accepted / Rejected
4. Algorithm (Pseudo code)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace WindowsApplication3
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
int dif, yob, ytoday;
yob = Convert.ToInt32(textYearOfBirth.Text);
ytoday = Convert.ToInt32(textBoxToday.Text);
dif = ytoday - yob;
label1.Text = Convert.ToString(dif);
if (dif < 18)
{
MessageBox.Show("Sorry, Request Rejected. You are too young");
}
else

{
MessageBox.Show("Your Registration was accepted");
}
}

}
}
Output
Age more than 18
Age below 18
5. Problem Solving Description
The first step was Problem Identification. The owner of the purchase system was able to identify the problem in the limitation of age of system users. The solution was suggested to be automation. The next step was analysis, to weigh the impact of the current system which could lead to non-compliance with the government directives, restricting minors from using the purchase system.
The third step was Requirement Specification to decide on the input and the output data items such as the year of birth, the current year and the age. The next step was solution Design. The design of the system was done using flow chart and process flow. The fifth step was the implementation of the solution. The algorithm (pseudo code) was created in C#, as a graphical user interface application. The final stage was to test the pseudo code and to observe the system response for different ages.
