Using classes

[apedosmil8]

I am having problems with using classes. I'm not sure why this program will not run. I have pointed out the problem.

Thanks

#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;

class Student
{
private:

char lastname[40];
char firstname[40];
char id[10];
double gpa;
int score;


public:

Student(char lastname[], char firstname[], char id[], double gpa, int score); //the constructor

void showStudent();

void setName(char newFirst[], char newLast[]);

void setID(char newID[]);

int setGPA(double newGPA);

int setScore(int newScore);

char getDecision();

};

int main()
{

Student stu1 (Thomas, James, 55443 , 3.0, 1350 ); //This is the problem :(


}

/*************** ******/

Student::Info(c har lastname[], char firstname[], char id[], double gpa, int score)
{



}

/*************** ******/

void Student::showSt udent()
{

cout << setiosflags(ios ::fixed) <<setprecision( 1);

cout << setiosflags(ios ::left);

}

Though you have a constructor (good) you're not doing anything with it. Your constructor should have code in it that will use those values. Also, the string variables should be passed inside quotes.

P.S. I believe --though I'm not sure-- common practice is to use "char* myString", not "char myString[]", though I think both will work.

I'm confused..

From my notes they have a similar constructor with void functions afterwards.

Our assignment shows using [] so I'm guessing its ok. This stuff is over my head right now.

This code:

Student stu1 (Thomas, James, 55443 , 3.0, 1350 ); //This is the problem

should be:

Student stu1 ("Thomas", "James", 55443 , 3.0, 1350 ); //This is the problem

The notation

char lastname[]

means that lastname is a array of char. In C++ the name of the array, inthis case lastname, is the address of element 0. Element 0 of a char array is a char and the address of a char is a char*. Therefore, these are equivalent:

char lastname[]
 or

char* lastname
