Static Functions in C++

Question

I\'ve read a few posts on here about static functions, but still am running into trouble with implementation.

I\'m writing a hardcoded example of Dijkstra\'s algorit

Answer 1

Are you sure the function is supposed to be static?

It looks as if you want just a function? in your header file:

#ifndef DIJKSTRA_H
#define DIJKSTRA_H
void dijkstra(); 
#endif

in your cpp file

void dijkstra() {
   /* do something */
}

in your main file:

#include "yourcppfile.h"

int main(int argc, char **argv) {
    dijkstra();
}

if you really want a static function you have to put it into a nested class:

class Alg {
  public:
    static void dijkstra();
  /* some other class related stuff */
}

the implementation somewhere in a cpp file

void Alg::dijkstra() {
  /* your code here */
}

and then in your cpp file where the main resides

#include "your header file.h"

int main(int argc, char **argv) {
  Alg::dijkstra();
}
