how do i count characters after i get words from text

[aznairjordan]

i found out how to get each individual word from a text file. Now i am trying to limit each line to a certain number of characters. If the line limit is 10 and the word "string" starts at position 8, i need to make a newline and put "string" on the new line. I want to count characters to control the limit, however i do not know how to count the characters given that i got the words from a text file.

Here is my code so far:

int rearrange(int lineLength, istream& inf, ostream& outf)
{
	int charInLine = 0;
	const int maxLength = 10000;

	getWord(inf, outf);

	for(int i = 0; i < maxLength; i++)
	{
		
	}
	

	return 0;
}

int getWord(istream &inf, ostream &outf)
{
	char sentence[100000];
	
	while(!inf.eof())
	{
		inf >> sentence;
		outf << sentence << " ";
	}

	return 0;
}
