# Odd or even using pointers in c

These are some more logics to check even or odd. Using c language, the input and output are 0 and 1. Its output is identical to the input in the even position but inverted in the odd position. For example, input it output How to do this? Write a program that: Takes integer inputs until 0 is given, 1.

Calculate the sum of all odd numbers, 2. This program can be done by both for loop and while loop. But you are instructed to do this with while loop. Any integer number is represented in binary form. An even number's LSB will always be 0. An odd number will have the LSB, always 1. The LSB will tell you if the number is even or odd. Post a Comment. C program for odd or even number.

If a number is perfectly divisible by 2 it is known as even number. The remaining numbers which are not perfectly divisible by 2 is known as odd number. All the integers will either be even numbers or odd numbers. In this blog we will understand how to check whether a number is even or odd using C program. There are various ways in which we can check whether a given number is even or odd.

Following would be the flow diagram for the odd or even program:. Now, let ius look at the code to check whether a given integer is odd or even. In this program we checked whether the given number is returning 0 or 1 remainder when we divide it with 2.

You can also use conditional operator to verify the same condition which we have discussed earlier. You can also check whether the given number is even or odd using bitwise AND operator. Now after going through the above programs you would have understood how to check whether a given number is odd or even in C programming. I hope this blog is informative and added value to you.

All solutions are in C language. To summarize our programming questions list does not contain only answers In addition to, it also contains all the aspect of the problem, if any programming questions have multiple solutions then we try to add all possible solution of the problem actually programming problem.

We also divide all the c programming questions to multiple levels. Levels are nothing but complexity and toughness of programming questions.

## Find odd & even numbers using function - C

Therefore all the c programming questions are also separated by the categories. This is a high-level section for legendary programmers or thinkers, this section can help you to become a pro programmer. In this section, two categories are the number pattern and start pattern. I just keep the pattern programming and number programming in separate. All the tricky questions or we can say that number programming or start pattern programming solutions of c programming questions and answers are below. Hacker Rank 30 Days of Code Solution. Saturday, April 11, Tutorials Bookmarks. Find the maximum between the three numbers. Check whether a number is negative, positive or zero.

Check whether a number is divisible by 5 and 11 or not. Find whether a number is even or odd. Check whether a year is a leap year or not. Check whether a character is an alphabet or not. Input any alphabet and check whether it is vowel or consonant.Given a Linked List of integers, write a function to modify the linked list such that all even numbers appear before all the odd numbers in the modified linked list.

Also, keep the order of even and odd numbers same. Method 1 The idea is to get pointer to the last node of list. And then traverse the list starting from the head node and move the odd valued nodes from their current position to end of the list. Algorithm: …1 Get pointer to the last node. Method 2 The idea is to split the linked list into two: one containing all even nodes and other containing all odd nodes.

And finally attach the odd node linked list after the even node linked list. To split the Linked List, traverse the original Linked List and move all odd nodes to a separate Linked List of all odd nodes. At the end of loop, the original list will have all the even nodes and the odd node list will have all the odd nodes.

To keep the ordering of all nodes same, we must insert all the odd nodes at the end of the odd node list. And to do that in constant time, we must keep track of last pointer in the odd node list.

Node next. Node int d. Python program to segregate even and odd nodes in a. Function to initialise the node object. Get pointer to last Node. Consider all odd nodes before getting first eve node. Break the link between prev and curr. Make next of curr as None. Move curr to end. Make curr as new end of list.

Update curr pointer. We have to set prev before executing rest of this code. Given a reference pointer to pointer to the head. Put in the data. Make next of new Node as head. Move the head to point to new Node. Utility function to print a linked list. Driver program to test above functions. This code is contributed by Arnab Kundu.Write a C program to input a number from user and check whether given number is even or odd using functions.

That's correct for the limit of your for loops, but you shouldn't be using it inside the loop bodies.

### Even and odd numbers using pointers in c

In the loops, i is the pointer to the current element of the array. Learn more. Find even numbers in an array using pointers Ask Question. Asked 3 years, 5 months ago. Active 3 years, 5 months ago. Viewed 2k times. I am trying to find the even numbers in the array arr[]; using pointers. Derek Derek 1 2 2 bronze badges. Please post sample input, and expected output. I suggest looping through your arrays based on an index into the array. That's assuming you have a reason to use pointer arithmetic instead of subscripting for some reason maybe it's an assignment requirement?

So it becomes necessary to learn pointers to become a perfect C programmer. Let's start learning them in simple and easy steps. A pointer is a variable whose value is the address of another variable, i.

Like any variable or constant, you must declare a pointer before using it to store any variable address. Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. However, in this statement the asterisk is being used to designate a variable as a pointer. The actual data type of the value of all pointers, whether integer, float, character, or otherwise, is the same, a long hexadecimal number that represents a memory address.

The only difference between pointers of different data types is the data type of the variable or constant that the pointer points to. There are a few important operations, which we will do with the help of pointers very frequently.

## Find odd & even numbers using function - C

It is always a good practice to assign a NULL value to a pointer variable in case you do not have an exact address to be assigned. This is done at the time of variable declaration. A pointer that is assigned NULL is called a null pointer. The NULL pointer is a constant with a value of zero defined in several standard libraries.

In most of the operating systems, programs are not permitted to access memory at address 0 because that memory is reserved by the operating system. However, the memory address 0 has special significance; it signals that the pointer is not intended to point to an accessible memory location.

But by convention, if a pointer contains the null zero value, it is assumed to point to nothing. Pointers have many but easy concepts and they are very important to C programming. Passing an argument by reference or by address enable the passed argument to be changed in the calling function by the called function.

C allows a function to return a pointer to the local variable, static variable, and dynamically allocated memory as well. C - Pointers Advertisements. Previous Page. Next Page. Live Demo. Previous Page Print Page. Array of pointers You can define arrays to hold a number of pointers. Pointer to pointer C allows you to have pointer on a pointer and so on. Passing pointers to functions in C Passing an argument by reference or by address enable the passed argument to be changed in the calling function by the called function.

Return pointer from functions in C C allows a function to return a pointer to the local variable, static variable, and dynamically allocated memory as well.
