2. Jim is developing software for automating the slot booking process for a video game parlor. Customers fill the Booking Request form with the details of the game, such as the name, number of players, and complexity level. They hand over the form to the booking officer at the parlor. Depending on the availability, the booking officer reserves the time slots and the play station for customers.

using system ;

public class gamedetials

{

string fname ;

string lname ;

int noofplayer ;

int level ;

public static void getGameDetail ()

{

console.writeline (" enter your first name" );

fname= console.readline();

console. writeline ( " enter your last name" );

Lname-console.readline();

console.writeline( "enter no of players");

nooFplayer=convert ToInt32(console. readline() )

console. writeline(" entercomplexity level number:");

level= convert ToInt32(console.readline());

Console.ReadLine();

3. TechnoSoft, a leading software company, has developed an application for maintaining the scores of games in a video game parlor. If the new score is greater than the stored top score, the following program should interchange the values of the variables Top_score and New_score. However, the program does not generate the desired output. Identify the error in the following program and write the correct code: using System; class Interchange { int Top_score; int New_score; int Temp; void Swap() { Top_score=5; New_score=10; Temp=top_score; New_score=Top_score; Top_score=New_score; } void Display() { Console.WriteLine("The new value of top score is:"); Console.WriteLine(Top_score); Console.WriteLine("The old value of top score was:"); Console.WriteLine(New_score); } static void Main() { Interchange I1; I1.Swap(); I1.Display(); Console.ReadLine(); } } (Duration: 25 min
using System;

David is a cricket coach of a local team. He is analyzing the performance of one of his batsman. For this, he wants a program that should accept the number of recent matches for which the scores of the batsman need to be analyzed. After this, the program should accept the scores of the batsman for these matches, and then display the scores in ascending order. Help David create the program. Hint: Declare an integer array with a maximum capacity of 100 elements.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
//Sorting of a Number
namespace chapter4
{
class Program
{
static void Main(string[] args)
{
int[] a = new int[100];
Console.Write("Enter the number of recent matches for which the scores of the batsman need to be analyzed:");
string s = Console.ReadLine();
int x = Int32.Parse(s);

Console.WriteLine("======================");
Console.WriteLine("Enter the scores:");
Console.WriteLine("======================");
for (int j = 0; j < x; j++)
{
string s1 = Console.ReadLine();
a[j] = Int32.Parse(s1);
}
int limit = x - 1;
for (int pass = 0; pass < x - 1; pass++)
{
for (int j = 0; j < limit -pass; j++)
{
if (a[j] > a[j + 1])
{
int k = a[j];
a[j] = a[j + 1];
a[j + 1] = k;

}
}
