The size of the pointer sizeof(ptr). Here should be 4.
The size of the pointee sizeof(*ptr). Here should be 1.
The size of a C string strlen(ptr). String must be null-terminated.
The size of a C++ string str.length().
Note: sizeof will not give you the total size of an array unless you are applying it directly to the array itself (as opposed to a pointer which happens to point to the array).
