After executing the following code I receive the errors:
a.c: In function `insert':
a.c:59: error: incompatible types in assignment
I have no problem when first_name in the structure is an int. I can
easily assign a default value in the insert function. But I would like
to allow full strings to be sent to the field from the insert
function....Any ideas?
The code is:
