c - format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘char (*)[64]

Question

I'm creating a program using C, and I have this line in my code :

scanf("%s", &path);

When I compile the source file, I get this warning :

main.c:84:2: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘char (*)[64]’ [-Wformat]

And this is the declaration for the path variable :

char path[64];

Why I'm seeing this error? And how can I solve it ?

Answer 1

An array is already a pointer-like object (as dreamlax points out). You don't need the & operator, since declaring

char path[64];

is equivalent to setting path to a pointer to a 64-byte region of memory.
