Question

suppose,a=1,b=2 and c=3, Write an algorithm to exchange the value of c and c will take the value of a​

Answer 1

Step-by-step explanation:

Swapping four variables without temporary variable

Suppose we have four variables a, b, c, d and we want to perform swapping of these variables in the following manner

a = b, b = c, c = d, d = a

without using any other fifth or temporary variable

Solution :

Step 1. Swap a and b without using any other variable

a = a + b

b = a – b

a = a – b

Step 2. Swap b and c without using any other variable

b = b + c

c = b – c

b = b – c

Step 3. Swap c and d without using any other variable

c = c + d

d = c – d

c = c – d
