Pointer to Structure | C++ Pointers to Structure - A pointer is a variable that holds a memory address. This address is the location of another object (typically, a variable) in memory. That is, if one variable contains the address of another variable, t
In C, struct is part of the type name for every structure defined. (C++ makes this keyword optional, and so the type might just be called Point. But we're talking about C now.) Each struct Point variable has two “sub-variables” (called fields), x and y. So you can write the ...
In this tutorial we are going to learnhow a structure pointer is declared and how we can use (access and modify the value of structure members) structure pointer? Declaration of structure pointer Just like another pointer variable declaration, a structure pointer can also be declared by preceding...
Structure Pointers These are the pointers that point to the address of a structure, a user-defined data type. With the help of structure pointers, complexdata structureslike linked lists, trees, graphs, etc., are created. The syntax of a structure pointer in C is as follows: ...
In the above program, we first simply printed the addresses of the array elements without using the pointer variableptr. Then, we used the pointerptrto point to the address ofa[0],ptr + 1to point to the address ofa[1], and so on. ...
To make use of a pointer and it’s capabilities – the address of a particular memory location must be assigned to the pointer.It is possible to assign address of single variable or that of an array or the address of a structure etc to a pointer variable.This capability makes pointers the...

To access dynamic data structures such as linked lists, trees, and queues. To access elements of an array or members of a structure. To access an array of characters as a string. To pass the address of a variable to a function.
Generally, pointers are rarely used when coding in .NET. However there are cases when their utilization can be useful. For example, we might interface with unmanaged functions (e.g. from a C library) and we need to pass a data structure to the unmanaged code. This is common in scenarios...
