Reversal of a sentence

[voidmaingetch]

I'm using Turbo C++ and I have a problem:
how do you reverse the words of a string??
eg:

If i type:
I GO TO SCHOOL

program gives::

SCHOOL TO GO I

-voidmaingetch

Hi voidmaingetch!
You should ask your question in the C/C++ Forum. The chance of getting an answer quickly is much greater there.

I think the best way to do that is to put all the words into an array and then iterate over the array backwords printing out each word. What have you tried so far?

I'd recommend strtok(). I'm not sure the best algorithm for doing this, but you might parse through the string, putting each word in a vector, then you can iterate backwards through the vector and print them out.

Any other implementation ideas? It seems there should be a better one than mine...

I think that strtok() is mostly C and for C++ I think the best way to get the words would be to iterate over a string that you used for getline():

string line;
getline(cin, line);
 
for (int x = 0; x < line.size(); x++)
{
    // if line[x] is a letter; add to word
    // if line[x] is a space; close word and start new word
}
 

It might be easier with cin though.

That's a good idea. You can read them in and reverse them on the spot (you know that the first one you read will be the last, etc...)

Is the OP not using C++?

That sentence was really two ideas, e.g.:

I think that strtok() is mostly C; for C++...

That sentence was really two ideas, e.g.:

Ah, that would make more sense. Yeah, I like strtok() and probably use it more than I should...
