C++ Translate English Sentence to Pig Latin

[ahoway]

I am having problems entering a sentence for translating into pig latin. It is set up now to read the entire sentence as one word. I would like to know how to look at each word in the sentence so that each word is translated to Pig latin seperately. Attached is my code: Thank you for your time.

the out put for hello world comes out :ello worldhay
I want it to say: ellohay orldway

Check out the C++ function strtok(). I think you can use that to separate out the words, as long as you know the delimiters that will be separating them (like spaces).

[manontheedge]

you can read it in as characters, and signal the end of a word every time it sees a space...that's one way to do it...by avoid strings entirely.

do either of you know where I get a tutorial on this? My book is not very clear and none of my professors example programs show this. Thanks

For manontheedge's method, it's less of something there would be a tutorial on, you would create a loop that accepted a char, and test it against the value for a 'space', and then did whatever else you wanted.

Read the whole string the way u have done in ur program.
then extract out each word till u find a space
copy the word to another string from subscript 1 , and concatenate 0th subscript and "way"
continue dor the whole length of the string

I have solved the first problem, now I need help with...

1.Program repeats until user enters a null string
2.Prompts the user to enter a string or just return to terminate

here is my new code: Thank you in advance!

I think your best bet is a while loop.

Now I can get the loop to work, but my English to pig latin is gone?

Yeah, I'd use the while loop to test the input, and repeat output, then go on to the program, not do the program in a while loop...`

[ahoway]

Thanks for all the help. I changed my program around and this is what I came up with. It does exactly what the standards called for.

// piglatin_2.cpp : Defines the entry point for the console application.
//
// PigLatin.cpp : Defines the entry point for the console application.
//This program will take in a string of characters from a sentence. It will
//then look at each word and convert the word to Pig Latin. It will then
//put the sentence back toghther in Pig LAtin form. It has a loop inside it
// to continuously test for new strings in which the user types in. If there
//is nothing to be typed in and the NULL condition is satisfied the program will then
//break out of the loop..Does not look for punctuation
