Pointer Rules in C programming language.Here is the list of c programming pointer rules, these points must be remembered while you are working on pointers to avoid compilation and run time errors.Few rules about C pointers 1) A pointer variable does not store value directly just like int, fl...
In simple terms, variable store values and pointers store the address of the variable. Pointer Declaration: Like variables, pointers should be declared before using it in the program. We can name pointers anything as long as they obey C’s naming rules. Syntax:Data_type * pointer_variable_nam...
The typedef is a keyword used in C programmingto provide some meaningful names to the already existing variable in the C program. It behaves similarly as we define the alias for the commands. In short, we can say that this keyword is used to redefine the name of an already existing variab...
There a lot of cause to arise the dangling pointers in C language but here I am describing some common cause that creates the dangling pointer in C. Access a local variable outside of its lifetime Basically, lifetime means “Storage Duration”. If an identifier is referred to outside of ...
Learn the concepts of Array of Pointer and Pointer to Pointer in C Programming. Understand their definitions, usage, and practical examples.
C program, using pointer for string comparison
Write a C program where a function returns a pointer to the maximum of two numbers. Write a C program in which a function returns a pointer to a dynamically allocated array containing computed results. Write a C program to implement a function that returns a pointer to a structure after pro...
Program 6.1 shows an example of a function that swaps the contents of two variables (a and b). Figure 6.4 shows how the compiler checks the parameters passed to the function and the return type. The function prototype, in this case, specifies that the parameters sent are pointers to integer...
Explanation: In the above program, pointer variable ptr stores the address of variable i. Then value and address of i along with the value of ptr are displayed. Note: The memory address displayed by the compiler can either be hexadecimal or a decimal number, depending on the compiler and th...
