What is () operator for three integer operands

Question

int a,b,c,z;
a=2;
b=4;
c=6;
z = (a,b,c);
cout << z;

output of above code is 6. I am not getting why it is 6 and what does this code mean?

Answer 1

well here comma operator also plays role...
when more than 1 value is assigned to a variable using parentheses separated by comma operator...
the rightmost value is assigned to the variable...
so value of z here is c = 6
