"An access violation (Segmentation Fault) raised in your program."

My C++ program compiles and works up until I call this function from main():

int uword(){fstream infile("numbers.txt");
fstream exfile("wordlist.txt");
string numb[numoflines];
string lines[numoflines];  
number = 1; 
line = 1;  
for(int i=0;i<numofline;++i)
    {
    getline (infile,number);
    numb[i] = number; //I think this is causing the problem
    getline (exfile,line);
    lines[i] = line; //This too
    }
infile.close();
exfile.close();    
string yourword;

Something here causes it to crash, in the debug it pops up with "An access violation (Segmentation Fault) raised in your program."

EDIT: My mistake was using !infile.eof in the for loop.

Not a direct answer, but I believe it's a good one...

Use The Debugger! GDB should suspend at the exact line when the segmentation fault happens, thus giving you a very good hint about what the error is.

The getline function does not work the way you think it works.

Also, there could be more than numoflines lines in infile.
