Write the proghrams for the following:
1. given values for two boolean variables a and b, the expression evaluates to true if just one of a or b is true, but not if both are true or both or false i. (note: this is also called an "exclusive or" between a and b.)
2. given values for three boolean variables a, b, and c, the expression evaluates to true if an odd number (i. e. exactly 1 or 3) of the variables a, b, and c is true, and is false otherwise. a. note: use only boolean expressions. do not use if-elif-else blocks

a)

#include <iostream>

using namespace std;

int main() {

   bool a,b,c;

   cin>>a>>b;

   if(a^b)//X-OR operator in C++.

   c=true;

   else

   c=false;

   cout<<c;

return 0;

}

b)

#include <iostream>

using namespace std;

int main() {

   bool a,b,c,d;

   cin>>a>>b>>c;

   if((a^b)^c)//X-OR operator in C++.

   d=true;

   else

   d=false;

   cout<<d;

return 0;

}

Explanation:

The above written programs are in C++.There is an operator (^) called X-OR operator in C++.It returns true if the number of 1's are odd and returns false if the number of 1's are even.

In the if statement I have user X-OR operator(^) to find the result and storing the result in another boolean variable in both the questions.
