I have to write some code where I must format the output of a bunch of sentences in no more than 40 characters per line. I can't use hyphens to truncate words. The program must know if it's not going to fit that it must start a new line.
The input is coming from a file, and input into the program via ifstream.
I haven't tried anything yet, but wanted some suggestions so I can get going because I haven't, as of yet, found any function that can help me accomplish this.
The code I do have does a whole bunch of unrelated stuff to the input and I didn't want to fill up the post with jibberish.
I'm thinking that since I'm using strings I can use the length or size functions, but I don't see just yet how best to use them in this scenario.
I would just read it all into a string then walk through that string printing each character until you hit 40 characters then start a new line and continue walking through the string printing 40 character, ect. until you hit the end of the string.
string myString("how are you doing?");
int newLineChecker = 5;
for (auto i = 0; i != myString.size(); ++i)
if (i == newLineChecker)
newLineChecker += 5;
cout << endl;
cout << myString[i];
This code doesn't worry about if its breaking up a word so you will need to figure out something to figure out that part (Can't give you all the answers ;p), but it should give you something to start with.
