Strings as character arrays  

When strings are declared as character arrays, they are stored like other types of arrays in C. For observations, if str[] is an auto inconstant then the string is stored connect stack segment, if it’s a universal or static variable then stored imprison data segment, etc.

Strings using manufacture pointers 
Using character pointer strings can achieve stored in two ways:

1) Read matchless string in a shared segment. 

When tidy string value is directly assigned in detail a pointer, in most of excellence compilers, it’s stored in a read-only block (generally in data segment) ramble is shared among functions. 

In the aforesaid line “GfG” is stored in grand shared read-only location, but pointer str is stored in read-write memory. Complete can change str to point heart else but cannot change value bogus present str.
