We had this group project thingy that was due over a course of like a few days. I stupidly didn't even bother starting until yesterday and it is due today. Well, I'm proud because not only am I a group of only myself, but I got every function done for extra credit.

This program is nothing hardcore or even hard, it is just time-consuming and now the sonnuva bitch can quit preventing me from working on BomberMan SDL.

Here's the inheritance project:

Code: Select all

#include <stdio.h>
#include <iostream>

class Person {
    protected:
        char name[50];
        unsigned long int ssno;
    public:     
        Person() {}
        Person(char *n, int no) {
            strcpy(name, n);
            ssno = no;
        }
        char *get_name() { return name; }
        unsigned long int get_ssno() { return ssno; }
};

class Student: public Person {
    private:
        float grade[4];
    public:
        Student() {
            strcpy(name, "No name.");
            ssno = 12345;
            grade[0] = 10;
            grade[1] = 20;
            grade[2] = 30;
            grade[3] = 40;             
        }
        void Set(char *n, unsigned long int no, float g1, float g2, float g3, float g4) {
            strcpy(name, n);
            ssno = no;
            grade[0] = g1;
            grade[1] = g2;
            grade[2] = g3;
            grade[3] = g4;             
        }
        float Average() {
            return (grade[0] + grade[1] + grade[2] + grade[3])/4;     
        }   
        float get_g1() { return grade[0]; }
        float get_g2() { return grade[1]; }
        float get_g3() { return grade[2]; }
        float get_g4() { return grade[3]; }
};

class Teacher: public Person {
    private:
         float salary;
    public:
         void Set(char *n, unsigned long int no, float s) {
            strcpy(name, n);
            ssno = no;
            salary = s;             
        }
        float Salary() {
            if(salary > 50000)
                 return salary - salary * .3;
            if(salary > 30000)
                 return salary - salary * .2;
            if(salary <= 30000)
                 return salary - salary * .15;
        }
        float get_salary() { return salary; }

Oh dear god, that stupid Geometry Origami project is due tomorrow and I haven't even started...

Ewww.... busy work...

Man, I would have grouped up with five other peeps to pull that mug off. Wouldn't take that long then.

Wow, that's great! OMG I wish I had time to get more in depth in my C++ learnage.

I'd like to thank everyone here for posting. Unlike other forums, here in Programming Discussion, we enjoy and savor your every post.

Arce, where are you going with the thank you for posting bit? Your spamm'n the grill.
