I just started to study C++ by myself and having troubles..lot of troubles i especialy with (6),(7)...anyone knows CPP well enaugh?thank you people.....
I'm trying writing a program including information about a student in college:
(1)id number of the student (2)name of the student-static string of 20 (3)pointers array of 10 courses(each student studies maximum 10 courses) (4)array of final grades in the studied courses (5)every student can have data about less than 10 courses so the ammount of the actualy studied courses must(!!) be memorized/stored. (6)output function-student can be registered to course only if he stands by all the requirement for every course (7)input..
The MAIN function must present a menu for students wishing to make registration for courses and managing theirs grades,maximum students in college are 5...here my try but its wrong:(,is there anybody who knows how it supposed to look like?thanx!
---------
#include <iostream>

Class student {

long student_number;

char student_name[20];

Course *course_arr[10] ;//pointers array??

int grades_list[10];

int Actual_courses_studied();

require() { // supposed to be the (6)..dont know how to start even define it..

Input_func() ;

Output_func() { }

}

int Student :: Input_func() {

if require()<>NULL

cout<<"type student name and id"

cin>> student_number>>student_name }

int Student::Actual_courses_studied() {

for (i=0,i<10,i++)

if *course_arr[i]<>NULL

z++

return z }

void main() {

student A;

A.Input_func();

I really ought to stop helping the homework questions, especially when the OP hasn't learned the importance of white space nor correct grammar. Oh well, it's not like I'm actually going to write much code tonight.

Course *course_arr[10] ;//pointers array??
Technically, it's an array of pointers. Pointers array just makes it sound like a few pointers to an array. At least to me (and that's all I care about).

Class student {
int Student :: Input_func() {
Is it student or Student? Make up your mind and stick with it. Also, it's class, not Class.

Number 6: Output, eh? I'd probably store the final grade in the Course class. Then, in the student class, I'd probably pull something like:
void student::output() {
Course **p = course_arr
while (*p)
(*p++)->output();
}
...Which should work, but only if you've initialized your course_arr[] to 0 somewhere in your constructor. (I.E. for (int i=0;i<11; ++i) course_arr[i]=0;) (Note: This would eliminate the need for the "total courses taken" variable.) EDIT: Oh yeah, you'd also have to increase the array by one.

Number 7: Input. Same logic as #6. Depending on what you're inputting, you might need to add a new Course before you call its input().

"I just started to study C++ by myself"

Hmm, is it just coincidence that your "self-study" includes what appears to be a standard homework question?
