Answer #1

using System;

//System.IO contains File Class which we use to read from file

using System.IO;

class MainClass {

//main function

public static void Main (string[] args) {

//we try everything in try block if FileNotFoundException is raised it goes to catch block


//fileContents has all the line from the file

var fileContents = File.ReadAllLines("wronginput.txt");

Console.WriteLine("Contents of the file:");

//foreach loop takes each element from the list`

//so here we iterate through each name from list and print to console

foreach(var name in fileContents){



//initialize two strings temporarily for below use

string temp,temp1;

//here we start modification of string

Console.WriteLine("\nContents of the file with modification:");

//iterate through each name from the list which contains contents of the file

foreach(var name in fileContents){

//store the first character of string which is converted to upper in temp variable

temp = name[0].ToString().ToUpper();

//take substring from index 1 to last i.e except first char take the remaining and convert it to lower

temp1 = name.Substring(1,name.Length-1).ToLower();

//print to the console by concatenating both the above strings




//this catch block will hit only if FileNotFoundException occurs

catch (FileNotFoundException)


Console.WriteLine("File Not Found");
