CSE 220 System Fundamentals I Lecture 10: Pointers and Arrays in C Programming

These flashcards cover key concepts about pointers and arrays as discussed in Lecture 10 of CSE 220.

Pointer to const int

A pointer that points to a constant integer, meaning the value it points to cannot be modified.

Const pointer to int

A pointer that cannot be changed to point to another integer, but the integer value it points to can be modified.

Pointer Arithmetic

The ability to perform addition and subtraction on pointers, allowing traversal through array elements.

Function returning a pointer

A function can return a pointer to a variable, enabling the use of addresses in function calls.

strlen function

A function that calculates the length of a string by searching for the null character.

Compound literals

A feature that allows creation of unnamed arrays that can be initialized at the point of declaration.

Array parameter in a function

An array name in a function's parameter list is treated as a pointer to the first element of the array.

Multidimensional arrays

Arrays that have more than one dimension, with elements stored in a specific order, usually row-major order.

VLAs (Variable-Length Arrays)

Arrays whose length is determined at runtime rather than compile time.

Function declaring pointer type

The declaration of a pointer type may vary depending on the structure of arrays it points to.
