Using an ampersand in scanf()
- by Rob
When I compile scanf("%s", &var);, gcc sends back a warning:
warning: format ‘%s’ expects type ‘char *’, but argument 2 has type ‘char (*)[20]’
however when I compile scanf("%s", var);, no warning is applied. Both pieces of code work and the book I am reading specifically says to use the ampersand, but even it doesn't in some of the examples.
My question is, should I continue to use the ampersand, even when the book doesn't specify?
