C Program to Swap two numbers using XOR Operator

C Program to Swap two numbers using XOR Operator

Generally Swaping two number requires three variables , Let's Take look at Procedure of swaping two Number
For Swaping Two numbers following procedure is used -

 Let x = 12 and y = 9 [ For our sake and simplicity consider number is of 4 bits ]

#include<stdio.h>
 
int main() {
   int j1, j2;
 
   printf("\nEnter First Number : ");
   scanf("%d", &j1);
 
   printf("\nEnter Second Number : ");
   scanf("%d", &j2);
 
   j1 = j1 ^ j2;
   j2 = j1 ^ j2;
   j1 = j1 ^ j2;
 
   printf("\n Numbers after Exchange : ");
   printf("\n j1 = %d and j2 = %d", j1, j2);
 
   return(0);
}

C Print Elements of Array using Recursion - Define our Recursive Function to print array elements & say printArray(int arr[], int start, int len). The function takes three parameters where first is array to print, second is starting

C++ Find Maximum & Minimum Numbers - Program should display all 'random elements' of array and minimum and maximum number in array on screen. Array size is fixed to 100 to change the size just change the 'Value of size'

Find the Length of Strings without strlen() - We are Counting the Number of characters in a given String to find out & display its Length on console. Upon 'execution' of this program, the user would be asked to enter string, then

C++ Program to Implement Vector in STL - C++ code to Implement Vector in STL. Insert element into the vector. Delete last element of the vector. "Size of the vector". Display by index. "Dislplay by iterator". Clear the vector

Relational Operators in C++ programming - In C++, This category of the operators is used to compare different values. The result of the operation is a Boolean value. The "Relational" operators are used in the form Operand1 and

C Code Check if an Integer is Odd or Even - C Language Program takes the given integer & checks whether the integer is odd or even. Take the integer to be checked as input. Find the remainder of the integer by dividing it by

Implement Randomized Binary search tree - Program demonstrates the implementation of Randomized Binary Search Tree. Function to check if tree is empty. And then make the tree logically empty. Functions to insert data.

Frequency of Characters in a C-style String - In this example, 'frequency of characters' in a String object is computed. To do this, "size()" function is used to find the Length of a string object. Then, the for loop is iterated until the
