The document describes a VB.Net console application that takes user input for a person's name, age, gender, and account balance. It then calculates 10% interest on the balance and displays all the input and calculated values. The application uses variables to store the input data, calculates interest by multiplying the balance by 10% and dividing by 100, and outputs the results to the console screen.

2. The first line of the program indicates the main( ) procedure. Sub Main() Dim Name As String Dim Age As Integer Dim Gender As Char Dim Balance As Decimal Dim Interest As Decimal 'input data Console.Write("Enter Name :") Name = Console.ReadLine() Console.Write("Enter Age :") Age = Console.ReadLine() Console.Write("Enter Gender :") Gender = Console.ReadLine() Console.Write("Enter Balance :") Balance = Console.ReadLine() 'Process Interest = Balance * 10 / 100 'Output Console.WriteLine("-----------------") Console.WriteLine("Name........:{0}", Name) Console.WriteLine("Age.........:{0}", Age) Console.WriteLine("Gender......:{0}", Gender) Console.WriteLine("Balance.....:{0}", Balance) Console.WriteLine("10% Interest is :{0:f2}", Interest) Console.ReadKey() End Sub Code Narrative Memory Screen

3. These lines create named memory locations to store the data entered by the program user. Name is string to store characters Age is integer to store whole numbers Gender is char to store a single character Balance & Interest are decimal to store numbers with digits after the point. Sub Main() Dim Name As String Dim Age As Integer Dim Gender As Char Dim Balance As Decimal Dim Interest As Decimal 'input data Console.Write("Enter Name :") Name = Console.ReadLine() Console.Write("Enter Age :") Age = Console.ReadLine() Console.Write("Enter Gender :") Gender = Console.ReadLine() Console.Write("Enter Balance :") Balance = Console.ReadLine() 'Process Interest = Balance * 10 / 100 'Output Console.WriteLine("-----------------") Console.WriteLine("Name........:{0}", Name) Console.WriteLine("Age.........:{0}", Age) Console.WriteLine("Gender......:{0}", Gender) Console.WriteLine("Balance.....:{0}", Balance) Console.WriteLine("10% Interest is :{0:f2}", Interest) Console.ReadKey() End Sub Code Narrative Memory Screen Name Age Balance Interest Gender
