Is this possible?

Hello!

So I am new to programming in C++ but have had some minimal programming experience in the past.

I am looking to create a program that will read in a variable number of words in a text file (will grow as I add new words to it), place them in an array variable (1 word per node), then select and print to the screen 10 random words from the array. This would be a program that would help me quiz myself on vocab words for learning foreign languages.

I just wanted to check to see if this is possible to do before I start banging my head against the wall on it

Thanks!

If you're thinking "array", you're stuck in the old world -- C++ has better containers for this than an array.

It's certainly possible. I'm not sure why you'd think otherwise.

Thanks

What would I use if not an array?
Would i have to put the text file like:

#1
"
word1
word2
word3
"

or
#2
"
word1 word2 word3
"

and would I just use a while loop until (ifstream wordfile, wordfile="")? to handle a dynamicly growing input file?

Thanks!

How about vector?

vector<string> should work for you.

You could also use a list.

keep it simple and use arrays
if you need functionality like resizing and erasing and reallocation use vector

Yes, either one is fine.

What's not simple about a vector? :P It'll probably make life easier if anything.

If anything, arrays are more difficult and error-prone than vectors.
vector isn't difficult and is recommended since there is no fixed amount of lines. Just use push_back instead of assigning. It's a cinch.
