type cast or conversion?

[steviecrawf]

I want to read 4 char from a file and then store them at an array so i do:

fread (&i_r_quan, sizeof (char), 4, f_ptr);

After checking these characters I need to store them in a structure as an integer.
Does the following work by type conversion or do I have to type cast i_r_quan to an integer first:

strcpy (i_r_quantity, i_r_quan [4]);

Also will a null be added to i_r_quan automatically when I read 4 characters into the array?:

CHEERS!!

union conversion{
    char array[4];
    int i;
};

Try that on for size.

No, you need to use a routine like atoi or sscanf

If i_r_quantity is an int, then
sscanf( i_r_quan, "%d", &i_r_quantity );

No - you need to do this bit yourself as well
