Question $1$

Convert the following loop into a for loop

bool keepGoing $=$ true;

int count $=0$;

while $($keepGoing & & count $<mtext\; id="EditorElement\_999772"></mtext><mn\; id="EditorElement\_999773">3</mn><mi\; id="EditorElement\_999774">)</mi>$

$\{$

Console.WriteLine$($count$)$;

Console.WriteLine$("$Keep going?"$)$;

keepGoing $=$ Convert.ToBoolean$($Console$.$ReadLine$())$;

count$++$;

$\}$

Question $2$

The code in question $2$ currently has no validation. Check for the following cases:

Non$-$numeric input

Negative number input

Number greater than $19,000,000$ input

If any of the validation cases are encountered, output "error" to the user. Other deposit amount to the user.

Question $3$

Convert the following if$-$else into a switch case:

Console.WriteLine$("$Enter a username"$)$;

string ulnput $=$ Console.ReadLine$()$;

if $($ulnput $==$ "admin"$)$

Console.WriteLine$("$Nice try"$)$;

else if $($ulnput $==$ "user"$)$

Console.WriteLine$("$Too common!"$)$;

else if $($ulnput $==$ "password"$)$

Console.WriteLine$("$That comes later"$)$;

else

Console.WriteLine$("$Username set!"$)$;

Question $4$

Write a program to simulate feeding ducks at a park.

Repeat the following commands until the user wants to stop feeding ducks or has fed $20$ ducks:

Ask the user how many ducks they would like to feed

Display the number of ducks the user has fed

Ask the user if they would like to continue

If repetition stops because the user fed $20$ ducks or more, display the message "you have been overwhelmed by ducks."

Question $5$

Complete the method addingEvens$()$

The method has an integer return and two integer parameters

The method returns the sum of all even integer parameter values

A value is even if it is divisible by $2.$

$0$ is considered an even number for this problem

If no parameters are even, the method returns$-1$

For example: addingEvens $(2,4)$ returns $6,$ addingEvens $(3,8)$ returns $8,$ addingEvens returns $-1$

Call the method from the main $3$ times with the following arguments

Two even numbers

One even and one odd number

Two odd numbers
