a pair of number enclosed in parentheses

Here is a block of code. Can anyone explain what it means to have a pair of numbers enclosed inside parentheses. (This is in C++.)

    int a = 2, b = 2, c = 3, d = 1;
    if((a,b)<(c,d))
        cout<<"case1"<<endl;
    else
        cout<<"case2";

Or if the value are changing or taken as an input by user you can use && (and), || (or) logical operators to sort out your codes

if ((a<c) && (b<d))

or

if ((a<c) || (b<d))

That way you can make cases the way you like. Check about operators here http://www.cplusplus.com/doc/tutorial/operators/

That's the comma operator; it evaluates the thing on the left, throws the result out, and returns the result on the right. Since evaluating an int variable has no side-effects, that if is semantically equivalent to 

if(b < d)
