Suppose you have two variables x and y and you want to swap their values. The usual way to do this is using another temporary variable: temp = x; x = y; y = temp; However, the interchange of two variables can be done without the temp variable: x = x + y; y = x - y; x ...
*/ void Swap(int *a, int *b, int mode) { switch (mode) { case 0: /* Swap using a third variable tmp, traditional swapping method */ tmp = *a; *b = *a; *a = tmp; break; case 1: /* Swap using bitwise XOR, sequence point introduced using comma */ (*a ^= *b), (*...
Program to interchange/swap two numbers using pointers in C++. To swap two numbers using pointers, we will first store the values in normal variables and declare two pointers to them.
The simplest method to swap two variables is to use a third temporary variable : define swap(a, b) temp := a a := b b := temp Pictorial Presentation: Sample Solution: C Code: #include<stdio.h>voidswap(int*,int*);intmain(){intn1,n2;printf("\n\n Function : swap two numbers u...

To swap the contents of two strings (say s1 and s2) without the third, first of all concatenate them and store in s1. Now using the substring() method of the String class store the value of s1 in s2 and vice versa. Example Live Demo public class Sample { public static void main(...
The simplest method to swap two variables is to use a third temporary variable : define swap(x, y) temp := x x := y y := temp Sample Solution: JavaScript Code: // Declare and initialize two variables, x and y, with the values 20 and 40, respectively.letx=20;lety=40;// Output...
