Study Notes
Pointers and Variables
- A pointer initialized to a variable of type float contains the memory address of that float variable.
- A pointer can point to a variable of a different type than the pointer type.
- A declared but not initialized pointer has no value.
- The value of a pointer is always an address of a variable.
- The value of an initialized pointer is the address of the variable it is initialized to.
Function Argument Passing
- It is possible to pass a variable to a function by its value or by its address.
- It is possible to change the value of a local variable in another function by passing its address.
Dynamic Memory Allocation
- In C, dynamic memory allocation is done using functions such as malloc and realloc.
- These functions are used when the size of an array is not known in advance.
- The declaration of the malloc function returns a pointer to the allocated memory.
- The return type of data from malloc and realloc functions is a void pointer.
- Malloc and realloc functions return a pointer to the allocated memory space.
- Realloc function takes the current pointer and the new size as arguments.
Algorithms
- An algorithm is a well-defined procedure that takes some input and produces a corresponding output.
- An algorithm must satisfy certain criteria, including:
- Finiteness: the algorithm must terminate after a finite number of steps.
- Definiteness: each step must be precisely defined.
- Effectiveness: the algorithm must be able to be performed with a reasonable amount of effort.
- Correctness: the algorithm must produce the correct output for any given input.
