Hi guys im a beginner at programming i started a book for beginners im only on lopps now but as uasuall i googled and wondered off into classes i keep getting this error, i initialized the float variables in the class by using the constructor. I'm not sure if this is the right way, please help ::)

#include <iostream>
#include <time.h>
#include <string>

using namespace std;
// Function Declarations
string ToUpper(string string1);
///////////////////////////////
class Student
{
    float eMidterm;
    float eFinal;
    float eResearch;
    float ePresentation;
    float sMidterm;
    float sFinal;
    float sResearch;
    float mMidterm;
    float mFinal;
    // Constructor Function
public:Student();
    ////////////////////////// Grades Variables
public:
    int midterm;
    int presentation;
    int research;
    int finalexam;
public: float setEnglish(int midterm, int finalexam, int research, int presentation);
};
// Constructor Funtion used to Initialize the class members
Student::Student()
{
    eMidterm = .25f;
    eFinal = .25f;
    eResearch = .30f;
    ePresentation = .20f;
}
/////////////////////////////////////////////////////////////
