To initialize a pointer to null or to assign the null value to an existing pointer, a null pointer constant (NULL, or any other integer constant with the value zero) may be used.static initializationalso initializes pointers to their null values. ...
Many implementations also providestrict total orderingof pointers of random origin, e.g. if they are implemented as addresses within continuous virtual address space. Those implementations that do not (e.g. where not all bits of the pointer are part of a memory address and have to be ignored...
Although references always refer to valid objects or functions upon initialization, it is possible to create a program where thelifetimeof the referred-to object ends, but the reference remains accessible (dangling). Given an expressionexprof reference type and lettargetbe the object or function de...
Initialization of structure pointer As usual, structure pointer should also be initialized by the address of normal structure variable. Here is the syntax: strcuture_pointer_variable=&structure_variable; Access a structure member using structure pointer variable name ...
See struct initialization for the rules regarding the initializers for structs. Because members of incomplete type are not allowed, and a struct type is not complete until the end of the definition, a struct cannot have a member of its own type. A pointer to its own type is allowed, and...

What are the User defined data types in C language like structure, how structure is defined and how their members can be accessed through structure variable and pointer of structure variable.
Is this a correct and safe way to pass static pointers? I am unable to find memory leaks but executing this above code with higher input blocks indicates memory leaks. Please help. ANushree 6650 Hi, I suppose You mean: static stl* pt=&fd; //pointer initialization, just missed in the ...
C treats strings as arrays of characters conventionally terminated by a marker (the character \0). Aside from one special rule about initialization by string literals, the semantics of strings are fully subsumed by more general rules governing all arrays, and as a result the language is simpler...
This rule is only relevant to C. When designated initialization is used to initialize objects in an array, implicit array size specification may lead to errors. It is because changing object...
