Part 2: Console applications.

1. Write C# program to display welcome to C# programming

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

Console.Write("welcome to");

Console.WriteLine("C# programming");

}

}

}

2.Write C# program to Calculating the product of three integers.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

// Variable Declaration

int x; // stores first number to be entered by user

int y; // stores second number to be entered by user

int z; // stores third number to be entered by user

int result; // product of numbers

//****************End variable declaration

Console.Write( "Enter first integer: " ); // prompt for input

x = Convert.ToInt32( Console.ReadLine() ); // read first integer

Console.Write( "Enter second integer: " ); // prompt for input

y = Convert.ToInt32( Console.ReadLine() ); // read second integer

Console.Write( "Enter third integer: " ); // prompt for input

z = Convert.ToInt32( Console.ReadLine() ); // read third integer

result = x * y * z; // calculate the product of the numbers

Console.WriteLine( "Product is {0}", result );

}// end Main

}

}

Enum Example

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

int Sunday = 0;

int Monday = 1;

int Tuesday = 2;

int Wednesday = 3;

int Thursday = 4;

int Friday = 5;

int Saturday = 6;

System.Console.WriteLine(Sunday);

System.Console.WriteLine(Monday);

System.Console.WriteLine(Tuesday);

System.Console.WriteLine(Wednesday);

System.Console.WriteLine(Thursday);

System.Console.WriteLine(Friday);

System.Console.WriteLine(Saturday);

}// end Main

}

}

Output

Using Enum

namespace ConsoleApplication1

{

class Program

{

enum WeekDays

{

Sunday,

Monday,

Tuesday,

Wednesday,

Thursday,

Friday,

Saturday

}

static void Main(string[] args)

{

System.Console.WriteLine(WeekDays.Sunday);

System.Console.WriteLine(WeekDays.Monday);

System.Console.WriteLine(WeekDays.Tuesday);

System.Console.WriteLine(WeekDays.Wednesday);

System.Console.WriteLine(WeekDays.Thursday);

System.Console.WriteLine(WeekDays.Friday);

System.Console.WriteLine(WeekDays.Saturday);

}// end Main

}

}

Output

Sunday

Monday

Tuesday

Wednesday

Thursday

Friday

Saturday

namespace ConsoleApplication1

{

class Program

{

enum WeekDays

{

Sunday,

Monday,

Tuesday,

Wednesday,

Thursday,

Friday,

Saturday

}

static void Main(string[] args)

{

System.Console.WriteLine((int)WeekDays.Sunday);

System.Console.WriteLine((int)WeekDays.Monday);

System.Console.WriteLine((int)WeekDays.Tuesday);

System.Console.WriteLine((int)WeekDays.Wednesday);

System.Console.WriteLine((int)WeekDays.Thursday);

System.Console.WriteLine((int)WeekDays.Friday);

System.Console.WriteLine((int)WeekDays.Saturday);

}// end Main

}

}

3. Application that determines the larger of two numbers.

(Comparing Integers) Write an application that asks the user to enter two integers, obtains

them from the user and displays the larger number followed by the words "is larger". If the numbers

are equal, display the message "These numbers are equal." Use the techniques shown in Fig. 3.26.

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

int number1; // first number to compare

int number2; // second number to compare

// prompt for input and read first number

Console.Write( "Enter first integer: " );

number1 = Convert.ToInt32( Console.ReadLine() );

// prompt for input and read second number

Console.Write( "Enter second integer: " );

number2 = Convert.ToInt32( Console.ReadLine() );

// determine whether number1 is greater than number2

if ( number1 > number2 )

Console.WriteLine( "{0} is larger", number1 );

// determine whether number1 is less than number2

if ( number1 < number2 )

Console.WriteLine( "{0} is larger", number2 );

// determine whether number1 is equal to number2

if ( number1 == number2 )

Console.WriteLine( "These numbers are equal" );

} // end Main

}

}

Output

Enter first integer: 10

Enter second integer: 12

12 is larger

Enter first integer: 12

Enter second integer: 10

12 is larger

Enter first integer: 11

Enter second integer: 11

These numbers are equal
