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
