In C, a string can be referred to either using a character pointer or as a character array.  Strings as character arrays. When strings are declared as character arrays, they are stored like other types of arrays in C. For example, if string is an auto variable then string is stored in stack segment, if it’s a global or static variable then stored in data segment, etc. The C++ programming language includes these functions; however, the operators new and delete provide similar functionality and are recommended by that language's authors.[4] Still, there are several situations in which using new/delete is not applicable, such as garbage collection code or performance-sensitive code, and a combination of malloc and placement new may be required instead of the higher-level new operator. Dynamic memory management in C programming language is performed via a group four functions named malloc(), calloc(), realloc(), and free(). These four dynamic memory allocation functions of the C programming language are defined in the C standard library header file <stdlib.h>. Dynamic memory allocation uses the heap space of the system memory.
