Re: Question in C

[Harring Figueiredo <harringf yahoo com>]

  To the original author.

   Do you have a char or a <em> pointer </em> to a char ?

   1) if you have a char

       int i = (int) my_char;

   2) if you have a pointer to a char:  i.e  char* c = "34";

       int i = atoi(my_char);

 
 I think the wording is confusing a lot of people.
