Pointers CS362Pointers • A Pointer is a variable that can hold a memory address • Pointers can be used to: • Indirectly reference existing variables (sometimes simplifies code syntax) • Reference dynamically allocated memory • Read and write to binary files • Create complex data structures (such as linked lists)Pointers • Pointers holds an address instead of a data value • Used to access memory location where data resides • We say that the pointer “points to” data • Accessing memory via a pointer is called “indirect access” • We’ve used pointers for some time (reference parameters)Pointers • To declare pointer variables use the “*” character • It is used to both: • Declare a pointer variable • Access the values that the pointer variable points to • In the end, a pointer (or pointer variable) points to (holds the address of) a variable of a specific data type. • We will use the asterisk to define what type of data the pointer points to.Pointers datatype* variableName; • Asterisk indicates that the variable being declared is of type pointer-to-something • It is read as “points to datatype” • Asterisk can be at the end of datatype (as shown above), or at beginning of variable name: datatype *variableName; • Either works, but be consistent.Pointers • Example: float* fptr; • Declares a pointer called fptrthat can hold the address where a float value exists in memory • The pointer can only “point to” a float value (can’t point to any other data type)Pointers • Declared constants/variable have a unique starting address • Address indicates the beginning of the memory area • Addresses are assigned upon allocation • The address operator “&” when followed by a variable name provides the address of a variable pointerVariableName = &dataVariableNamePointers • Example: float num1, num2; float* fltPtr; num1 = 3.5; fltptr = &num1 • fltptr points to the memory location assigned to num1. • Pointers will always point to a specific type of memory (based upon the pointer type). • Type of data stored must match the pointer data type.Pointers • You access the data value pointed to by a pointer using the de-referencing operator “*” (which is also the indirection operator) • The asterisk followed by the pointer variable name access the value stored at the pointed-to address *ptrVariableName • This reads “the value that prtVariableName points to”Pointers • Example: num2 = *fltPtr; (num 2 is assigned the value that fltPtr points to) • num2 now has the value 3.5 stored at its memory location *fltPtr = 4.6; (where fltPtr points to (num1) is assigned the value 4.6) • num1 now has the value 4.6 stored at its memory locationPointers • Pointers can be initialized when declared like any other variable: int sum; int *sPtr = ∑ • Creates pointer sPtr and points it to the variable “sum” *sPtr = 5; • Assign the value 5 to “where sPtr points to” (“sum”)Pointers • It is always a good idea to initialize pointers when declared •

Beforehand, making it challenging to handle dynamic memory requirements. Additionally, unused memory cannot be reclaimed, resulting in potential memory wastage.? To leverage static memory management in high-performance C++ programs, consider scenarios where the memory requirements are fixed, or when the memory is reused consistently throughout the program’s execution.1.2 Dynamic Memory Management? Dynamic memory allocation allows us to allocate memory at runtime using pointers. Memory is allocated on the heap or stack, offering flexibility and adaptability to changing memory needs.?️ Heap memory is allocated by the programmer and should be manually deallocated to prevent memory leaks. Stack memory, on the other hand, is automatically allocated and deallocated within the function’s scope.⚖️ Choosing between heap and stack depends on factors like the size of the memory required and the duration of its usage. Stack memory is generally faster, but limited in size, while heap memory offers great flexibility but may incur higher overhead.1.3 Smart Pointers? Smart pointers are a powerful addition to C++ memory management. They automate the process of memory allocation and deallocation, preventing memory leaks and reducing errors caused by manual memory management.? The three commonly used smart pointers are unique_ptr, shared_ptr, and weak_ptr. unique_ptr ensures exclusive ownership of an allocated resource, shared_ptr allows shared ownership, while weak_ptr prevents circular references and provides non-owning access.? When working on high-performance C++ projects, smart pointers prove invaluable, providing memory safety and allowing you to focus on optimizing other aspects of your code.Memory Allocation Techniques for High-Performance ComputingNow that we have a solid

If a pointer does not point to a valid location, it can be initialized with the null pointer value • NULL means “points to nothing” float *myPtr = NULL; • To use NULL the library must be included • NOTE: Pointer variables can only store one of two values; an address or the value NULLPointers • Same type pointers may be assigned each other values int main() { float num = 5.5; float *ftPtr1 = NULL; float *ftPtr2 = # *ftPtr2 = 4.4; ftPtr1 = ftPtr2; cout Pointers • Common Mistake 1: • valid int *ptr1, *ptr2 (declares two pointers that point to integers) • invalid int* ptr1, ptr2 (declares a pointer, and an integer variable) • Common Mistake 2: given : int num; int *ptr; • valid ptr = # • invalid *ptr = # (ptr points to an integer location which cannot store the address of num) ptr = num; (ptr can only store an address or num, cannot accept an integer) Pointers • Pointers can point to any valid data type (including complex data types) • For example pointer to an array: • When using pointers with arrays the pointer will point to only one value within the array • The array name is actually a “constant pointer” to the first value in the array (e.g. a pointer to the subscript 0 element in the array) Given: const int MAX = 50; int grades[MAX]; int* gradesPtr; gradePtr = grades; (gradePtr now points to the first element in the array) gradePtr = &grades[5]; (gradePtr now points to the 6th element)Pointers • Warning: • When using pointers to arrays it is the programmer’s responsibility to ensure that you do not attempt to point past the end of the array (similar to boundary test) • Most C++ compilers will NOT identify an error in the code if you attempt to access past the end of the array, but the program will either crash or obtain strange or garbage values with the program runsPointers • Some math and relational operators can be used with pointers • For example, you can add units to a pointer • A unit is one storage unit (e.g. size of int, float, char) • Increments the address by size of data type • This can be used to access arrays rather than using the normal array syntaxPointers • Array Syntax vs Pointer Syntax const int MAX = 10; int numbers[MAX]; int* arrayPtr = numbers; (arrayPtr points to top of array) • accessing a cell using array syntax numbers[n] where “n” is a valid index value • accessing a cell using pointer syntax *arrayPtr *(arrayPtr + n) where “n” does not exceed the array sizePointers • Array Syntax vs Pointer Syntax • You can use either array or pointer syntax to initialize a pointer arrayPtr = &number[n] or arrayPtr = number + n; • You can use either array or pointer syntax to access an array value arrayPtr[n] = nn; or *(arrayPtr + n) = nn; •.
