Thread: Number Convert function

Code:

$ gcc -Wall foo.c
foo.c: In function ‘main’:
foo.c:9:9: warning: format ‘%d’ expects a matching ‘int *’ argument [-Wformat=]
    9 | scanf("%d,&digit");
      |        ~^
      |         |
      |         int *
$

Do you see what's wrong here?

Code:

scanf("%d,&digit");

Compare with

Code:

scanf("%d",&digit);
