Problem With Line Wrap Header File (segfault)

I am trying to program a header that prevents line wrap in the console. The problem is that I keep getting a Segmentation fault error in seemingly strange places. Here is the code:

Code:

---

#include <iostream>
using namespace std;

const int LINEWIDTH = 80; // this holds the width of the line
int counter1 = 1; // records the current position on the current line
int counter2 = 0; // records the current position in the string as it is being checked
int counter3 = 0; // records the length of the current word
int counter4 = 0; // records how much of the word has been printed
int counter5 = 0; // records the current position in the string as it is being printed
bool loop = true;

void lineWrap (char string[])
{
        while(counter1 < LINEWIDTH) // loops if the current position on the line is before the the specified line width
        {
                while(string[counter2] != ' ') // this finds the length of the current word, stored in counter3
                {
                    counter2++;
                        counter3++;
                }
                if(counter3 <= ((counter1 - LINEWIDTH) / -1)) // this checks to see if there is sufficent space to print the word before running
                {                                            // out of space on the current line
            while(counter4 != counter3) // this prints the current word
            {
                cout<<string[counter5];
                counter5++;
                counter4++;
                counter1++;
            }
                }
                else // if there isn't sufficent space to print the next word then this will start a new line and restart the line position counter
                {
                    cout<<endl;
                    counter1 = 1;
                }
        counter2++;
                counter3 = 0;
                counter4 = 0;
        }
}

I call the function with:

Code:

---

lineWrap("This is a long string of text to see if the lineWrap function will prevent linewrap");

---

Every time I compile and run the program though, I get this output:

Code:

---

This is a long string of text to see if the lineWrap functio

I realize that segmentation faults are a common issue, and I tried to search the forums for an answer, but I still couldn't figure out my problem. Thanks.

"while (counter1 < LINEWIDTH)" would seem to always be true, since you are very careful to not let counter1 go over the line. Something like "while (counter5 < strlen(string))" seems more like the point.

and what happens

Code:

---

while(string[counter2] != ' ')

---

if the last word does not have space at the end?

Both of you were right, thank you very much. I don't know how I missed both of those, but now I can get back to working on the function rather trying to fix some stupid error, thanks again.
