I can't believe a C++ instructor doesn't know page 1 C++ stuff. Try this:
// Travis Thoms
// 03/30/99    

#include <iostream>
#include <fstream>
#include <cmath>

ifstream inData;
int LegalNameInsteadOfReservedWord_class[100] =
{-1};
#define classnumber classNumber // to take care of undefined identifier

int classNumber = 0, Sum = 0, lessTen = 0, lessTwenty = 0, lessThirty = 0,
 lessForty = 0, lessFifty = 0, lessSixty = 0, lessSeventy = 0, lessEighty = 0,
 lessNinety = 0, lessHundred = 0, counter = 0;
float Mean = 0, Sample = 0, StdDev = 0;
int main()
{
//Preparation for file IO//

        inData.open("indata.txt");
        inData >> LegalNameInsteadOfReservedWord_class[classnumber];
        while (LegalNameInsteadOfReservedWord_class[classnumber] != -1) {
                classNumber++;
                Sum = Sum + LegalNameInsteadOfReservedWord_class[classnumber];
                if (LegalNameInsteadOfReservedWord_class[classnumber] < 10)
                        lessTen++;
                if ((LegalNameInsteadOfReservedWord_class[classnumber] >= 10) &&
                        (LegalNameInsteadOfReservedWord_class[classnumber] <=
19))
                        lessTwenty++;
                if ((LegalNameInsteadOfReservedWord_class[classnumber] >= 20) &&
                        (LegalNameInsteadOfReservedWord_class[classnumber] <=

                        (LegalNameInsteadOfReservedWord_class[classnumber] <=

                        lessSixty++;
                if ((LegalNameInsteadOfReservedWord_class[classnumber] >= 60) &&
                        (LegalNameInsteadOfReservedWord_class[classnumber] <=

                        (LegalNameInsteadOfReservedWord_class[classnumber] <=
100))
                        lessHundred++;

                inData >> LegalNameInsteadOfReservedWord_class[classnumber];

        }
        Mean = float (Sum / classnumber);
