Study Notes
- A float pointer contains the address of a float variable.
- A pointer can change the value of a variable through its address or variable name.
- A pointer can point to a variable of a different type.
- A pointer is initialized by assigning the address of a variable to it using the "&" operator.
- An uninitialized pointer is valid for reading and writing, but it contains a random memory address.
- Variables can be passed to a function by value or reference.
- Memory allocation functions in C include malloc, calloc, and realloc.
- Dynamic memory allocation is preferred when the size of an array is unknown.
- The return type of malloc and realloc is a void pointer.
- Algorithms should satisfy criteria such as input, output, determinacy, finiteness, and efficiency.
