Are you sure about the input file's name ??

fin.open("readLab5.cpp");

You almost got the code tags right, however next time you might want to utilize the "Preview Post" button to make sure that the code tags really are right.

double findWaist(double weight, int age) {
	double waist;
	if (age > 28)
		(weight/ 5.7) + ((age - 28) / 2) * .01;
	else
		waist = (weight/ 5.7);
	return waist;
}

after if (age > 28) it must be waist = (weight/ 5.7) + ((age - 28) / 2) * .01;
and fin.open("readLab5.cpp"); - why .cpp
