Pointers

Pointers are one of the core components of the C programming language. A pointer can be used to store the memory address of other variables, functions, or even other pointers. The use of pointers allows low-level memory access, dynamic memory allocation, and many other functionality in C.


What is a Pointer in C?
A pointer is defined as a derived data type that can store the address of other C variables or a memory location. We can access and manipulate the data stored in that memory location using pointers.


Syntax of C Pointers
The syntax of pointers is similar to the variable declaration in C, but we use the ( * ) dereferencing operator in the pointer declaration.
datatype * ptr;

 26 day  Call a Function Declared functions are not executed immediately. They are "saved for later use", and will be executed when they are called. To call a function, write the function's name followed by two parentheses () and a semicolon ; In the following example, myFunction() is used to print a text (the action), when it is called: Example Inside main, call myFunction(): // Create a function void myFunction() {   printf("I just got executed!"); } int main() {   myFunction(); // call the function   return 0; }

 42 day  C Structures The structure in C is a user-defined data type that can be used to group items of possibly different types into a single type. The struct keyword is used to define the structure in the C programming language. The items in the structure are called its member and they can be of any valid data type. Additionally, the values of a structure are stored in contiguous memory locations. Syntax struct structure_name {     data_type member_name1;     data_type member_name1;     ....     .... };
