Answer 1

You did not declare a temporary variable to store num1 value or num2 and finally assign this value to num2 or num2 but in the middle set num1 = num2 ;

Answer 2

You did not declare a temporary variable to store num1 value or num2 and finally assign this value to num2 or num2 but in the middle set num1 = num2 ;

I have to do it without declaration of a temporary variable i.e. in another way.

Answer 3

You can use bitwise xor operator here then. num1 = num^num2^(num1= num2)
