I'm really kinda lost on how to make this program. It's one of my last problems,

I need a program that would take data a line at a time and reverse the words of the line.

An example of the input and output would be...
apples and oranges --> oranges and apples

Any help would be much appreciated.

Thanks

Hey Dude, and welcome to GID

What did you have in mind ? I can think of some solutions :

First solution :
1. read each line with getline.
2. read the words into a doubly linke-list with head and tail, using strtok()
3. printing the lists from tail to head.

Second solution :
1. read each line with getline ...
2. read the next token with strtok and call your function recursively for the rest of the line.
3. when you get to the end of the tokens, you finish the recursion and print the words.

Third solution :
1. read each line with getline ... ...
2. read the words, using strtok() (or, you can have a pointer to char that you increment while generating the tokens on your own) into an array. Keeping count of the words in each line.
3. printing the array in the desired way.

What were you thinking of doing ?

I'm really kinda new to programming all together and haven't used getline or strtok before. Is there a good reference site where I can learn about these?

Thanks

try fgets instead of getline :
fgets reference

about strtok :
strtok reference

Best regards,
Kobi.

what about using a string array to store the letters and spaces, then just reversing the output of the array??

oh and by the way, are wetalking about taking data from a file, or from user input?

user input

how do I reverse the output of the array?

Do you use C or c++?

As Kobi Already said,
1. Read the string from the user, using getline or fgets.
2. Use strtok to split the string.
3. Store the splitted string into a string array, to be more simple.
4. Then add the strings in the string array, from the end, to a new string, which is the reverse of the original string.

You don't need either of these functions. You also didn't mention if you are writing C or C++. Giving us the details is important.

Set up a character (C) or string (C++) array to hold each word read.
cin and scanf will read one word at a time from the keyboard. This is probably the ONLY place I see scanf as useful
Read a word, put it in the array.
When done reading, output the array from the end.

I am using C, sorry about that.

Still struggling on how to have it assign a word to the string(Yes, i'm a beginner)
