How you can interchange two integer values using swap variable in c language?
t = a; a = b; b = t; // t is a third integer variable (swap variable) But here's a way without a swap variable, given as as a macro in C: #define SWAP(a,b) { if (a!=b) { a^=b; b^=a; a^=b; }} // Swap macro by XOR Once you define it, you can say swap(x,y) to swap x and y. The numbers kind of flow through each other and end up swapped.
How do you write a javascript to swap two numbers without using third one?
By using the algorithm of bitwise EORing (Exclusive ORing) the numbers together:If the two numbers are X and Y, then to swap them:X = X EOR YY = Y EOR XX =X EOR Ywill swap them.With knowledge of that algorithm, one then uses the syntax of Javascript to implement it.
How can you devise a way to interchange two variables A and B without using a third variable or register using Exclusive OR?
A = A xor B B = A xor B A = A xor B in C... A^=B; B^=A; A^=B;
How do you represent assignment by bitwise XOR operator?
The bitwise XOR operator is ^, or shift 6. The bitwise XOR assignment operator is ^=.
What is XOR in a c program?
a XOR b is a^b in C language
How do you swap two numbers with bitwise operator in c plus plus?
// Note: ^ is the XOR operator a = a ^ b b = b ^ a a = a ^ b
How do you swap two variables using bitwise operators?
a := a XOR b b := a XOR b a := a XOR b it works, but never use it in real programs do you know why its not used in real program??
How do you write a program in C to swap two variables without using the third one using XOR?
a=a^b; b=a^b; a=a^b;

Swapping without third variable?
There are two ways in which you can swap without a third variable. 1. Using xor operation swap( int *a, int *b) { *a = *a ^ *b; *b = *a ^ *b; *a = *a ^ *b; } 2. Using addition and subtraction swap( int *a, int *b) { *a = *a + *b; *b = *a - *b; *a = *a - *b; } }
Write a program to swap two numbers using function?
swap (int *a, int *b) { *a ^= *b; *b ^= *a; *a ^= *b; }
How many xor gates required for 4 bit parity checker?
3*xor- two input
How to swap two numbers by call by reference in c plus plus?
void swap(int& a, int& b ) { a^=b^=a^=b; }
Swap two numbers using call by value and call by reference?
You cannot swap two numbers using call by value, because the called function does not have access to the original copy of the numbers.Swap with call by reference... This routine uses exclusive or swap without temporary variable.void swap (int *a, int *b) {*a ^= *b;*b ^= *a;*a ^= *b;return;}
Is xor gate is a universal gate?
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.

What is it called when you swap the two numbers that you multiply?
I don't know.the Switch-A-Roo? not,it's inverse.
