Some good news for you: you already call this function in the line print(n); now it's the time to understand what is it. :-)

Please read the elementary C manual. Explaining such elementary things out of the more general context to the one who did not do it is extremely difficult, almost impossible. Makes little sense anyway. Read it first.

Some minor changes that will help you:

C++

// Recurression.cpp
//  ------------
 
#include <stdio.h>
 
void print(int n)
{
  static int c = 1;
 
  if (c == n+1)
    return;
 
  printf("%d\n", c);
  c++;
  print(n);
}
</stdio.h>

Need to define the print function in module Main.cpp.

C++

// MainC.cpp
// -------
 
#include <stdio.h>
 
void print(int);
 
int main()
{
  int n;
 
  scanf("%d", &n);
 
  print(n);
 
  return 0;
}
</stdio.h>
