I have a text file to be read "Mary had a little lamb its fleece was white as snow and everywhere that Mary went, the lamb was sure to go!".
The program should do the following:
1. count number of words in file
2. print all words, one per line
3. ask user if they want to change any words. if yes, then needs to ask user what word they want to change and what they want to replace it with. then execute a replacement.
4. output words with the replacement, if applicable.
5. output words by their length, and then output words alphabetically (all words one per line)

This is what I have so far, but there are many errors but I dont know how to fix it. Can anyone help?

The easiest to solve ones:

Line 18: "indexofsmallest" undeclared.
Where should this variable come from? What does it do?

Lines 35 and 61: "wordcount" undeclared.
You will need to count the words first and send this to the function in the arguments.

Line 145: Expected "}" at end of input
You are missing one close brace. Tac this on to the end. You will need to properly indent the couple of lines above it that are currently out of line.

i see what you mean at line 35 & 61, i meant to use "size" there; at 145. there should be a "}" at line 119 to end that if statement. thanks.
however, indexofsmallest is declared on lines 14 &42 as integers, and set equal to pass on 17 & 45. it is a method/function procedure i learned for sorting

You are doing too much at one time. Take the program a setp at a time so you can understand completely what you are doing.

First, read the file and output what is read. No more. Then

1. count number of words in file

Get that running completely (and properly) before moving on. When finished, add

2. print all words, one per line

Get that running completely (and properly) before moving on.

What you are doing is trying to get everything done at once which makes it hard to really understand the steps -- the forest/trees problem. It also makes debugging and error checking much more manageable. And with only one step at a time, you won't have the problem that

there are many errors but I dont know how to fix it.
