I wrote the attached code with the intention to get 42 as the output but I instead get an asterisks (*) I know that 42 is the ACII value of an asterisk. Please look at my code and see something I might have missed. The program is in C using the <unistd.h> library, I have to use the unistd.h and not the stdio.h for this code.

#include <unistd.h>

void      ft_putchar(char c)
      write(1, &c, 1);

void    ft_putnbr(int nbr)
    write(1, &nbr, 1);

void      ft_ft(int *nbr)
      *nbr = 42;

int      main(void)
      int a;
      int *ptr;
      char c;

      a = 7;
      ptr = &a;
