Pointer vs Array in C Explain the Union to pointer in C language C program to display relation between pointer to pointer Differentiate the NULL pointer with Void pointer in C language Difference Between Array and Pointer Difference between pointer and array in C Sum of array using pointer ari...
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...
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...
In the above program, the“memory_allocation”function allocated the memory toptr_1. Theptr_1acts like a double pointer and stored a string named“linuxhint”which is printed on the screen. Output Conclusion Thepointer to pointeris a useful concept in C programming language that allows you to...
/*function pointer example in c.*/ #include <stdio.h> //function: sum, will return sum of two //integer numbers int addTwoNumbers(int x, int y) { return x + y; } int main() { int a, b, sum; //function pointer declaration int (*ptr_sum)(int, int); //function ...
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 ...
We present two techniques to handle the high cost of run-time checking of pointer and array accesses in C programs: 'customization' and 'shadow processing'. Customization works by decoupling run-time checking from original computation. A user program is customized for guarding by throwing away ...
In this program, the elements are stored in the integer array data[]. Then, the elements of the array are accessed using the pointer notation. By the way, data[0] is equivalent to *data and &data[0] is equivalent to data data[1] is equivalent to *(data + 1) and &data[1] is ...
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...
In C programming language, the concept of pointers is the most powerful concept that makes C stand apart from other programming languages. In the part-I of this series we discussed the fundamental concepts around C pointers. In this article, we will try
