What does ~ mean in a logic operation?

Question

Just going through some random questions, I got stuck in this.
The program is as follows:

int main()
{
bool a = true;
bool b = false;
bool c = ~(a&&b)
cout<< c;

return 0;
}

I wonder what is the function of ~ operator.
Please help.

Tilde (~) is the bitwise complement operator. It takes the compliment of a binary value and adds a binary one to it.
