How do you implement a class in C? [closed]

Answer 1

I had to do it once too for a homework. I followed this approach:

1. Define your data members in a struct.
2. Define your function members that take a pointer to your struct as first argument.
3. Do these in one header & one c. Header for struct definition & function declarations, c for implementations.

A simple example would be this:

/// Queue.h
struct Queue
{
    /// members
}
typedef struct Queue Queue;

void push(Queue* q, int element);
void pop(Queue* q);
// etc.
///
