Write a small piece of code that prompts the user for a number and adds up the even

numbers from $1$ to that entered number using a while loop. You may not use for loops

for this assignment.

Enter the number to add the even numbers up to: $33$

LOOP$1$ total $=272$

$2.$ Write another small piece of code that prompts the user for $2$ numbers and adds up the

numbers between $($and including$)$ the numbers using a while loop. You may not use

for loops for this assignment. Add all the numbers, not just the even or odd ones.

Enter a lower and upper number to sum: $2244$

LOOP$2$ total $=759$

$3.$ Write another small piece of code that prompts the user for a file name and adds up all of

the numbers in the file using a while loop. Read until EOF $($end of file$).$

Enter a file name to read from: in$.$in

LOOP$3$ total $=18\mathrm{.}0000$

$4.$ Write another while loop around the code for #$3$ that prompts the user whether she or he

wants to prompt and read another file.

Enter a file name to read from: in$.$in

LOOP$3$ total $=18\mathrm{.}0000$

Do you want to do all of this again? y

Enter a file name to read from: in$.$in

LOOP$3$ total $=18\mathrm{.}0000$

Do you want to do all of this again? y

Enter a file name to read from: in

error opening file!

$5.$ Write another while loop that prompts the user for file name and reads & adds up the first

$5$ numbers in the file. $($Part $5$ executes even when the error message is printed in Part$4.$

For Part $4,$ you should use a break statement inside the if$,$ instead of doing a return

when the file doesn't open.$)$

Enter another file name to add $5$ numbers from: in$.$in

LOOP$4$ total $=18\mathrm{.}0000$

$6.$ Finally, add to Part #$5$ a while loop to print the $2$nd number in the file.

Enter another file name to add $5$ numbers from: in$.$in

second number $=-1\mathrm{.}0000$

LOOP$4$ total $=18\mathrm{.}0000$
