Yeah, typically the advice is to freadf() a line and then parse it, but if you have a really large block of data on one line then you can eat it piecemeal.
fscanf("%f ",&derp);
fscanf("%f ",&derp);
fscanf("%f ",&derp);
while(numberOfHerpLessThenFifteen)
{
fscanf("%f ", &mrMatrixomatic[mahIndex++]);
}
Just realize that fscanf can choke and die in a horrible fire if the formatting isn’t exactly correct.
