What is Operator ^+ | | |
Why does the following program works, and what is ^+ operator ?
int main()
{
int a = 10;
int b = 20;
int c;
c = a ^+ b;
printf("Value ===%d", c);
return 0;
}

There is no operator ^+ but there is an unary operator + (like there an
unary operator -) which you are using here.

There is no ^+ operator. The statement is being parsed as
c = a ^ (+b); | | | | re: What is Operator ^+

But the output is 30, it is acting same as the addition operator. | | | | re: What is Operator ^+

And ^ is XOR, which means "give me all the bits not in common between
the two operands". Since 10 is 8+2 and 20 is 16+4, this boils down to
being equivalent to addition. | | | | re: What is Operator ^+

There is no bit in common between 10 and 20, so there is no carry to
propagate and indeed exclusive or behave like addition for these operands.
But that's quite pecular to these values.

Try some different numbers. Two equal ones for example.

There is no ^+ operator, but there are ^ and unary +
operators. The statement is equivalent to
c = a ^ (+b);
.... which is equivalent to
c = a ^ b;

There is no "^+" operator. It's simply the binary "^" operator
followed by the unary "+" operator. It's equivalent to:
c = a ^ ( + b );

No, the output happens to give the same results as if you had used
addition, but that's only coincidental. It just happens to be that
both:
10 ^ 20
and
10 + 20
result in the value 30.

This is one of the cases where a half-adder is enough. :-)

Just in case you don't understand, the '+' is NOT addition here. It
represents the sign of the number, i.e. "positive b", or 1 * b, if it
helps you to think of it that way. In other words:
c = a ^+ b;
c = a ^ (+b);
c = a ^ (1 * b);
c = a ^ b;
If you used "c = a ^- b," it would be similar, except that you would
be performing the bitwise XOR operation on the negative value of 'b'.
Obviously the sign of the variable doesn't correspond directly to the
sign of the value. After all, if b==-4 then it would be the same as
the following:
c = a ^+ (-4);
c = a ^ (-4);
If you used ^-, it would be the following:
c = a ^- (-4);
c = a ^ -(-4);
c = a ^ 4;
