I am using VS2005 compiler and I am expecting following code to give compilation error.
int a=1, b= 2, c=3;
a = (b,c);
value of a after assignment is 3. As per my understanding it should give compilation error.
I would be happy to know if there is any valid reason behind this.
You are using the comma operator in C++, it is not commonly used. This works as follows
It evaluates
<expression1>and discards the results and then evaluates<expression2>and takes the result of that is returned as the value of the whole expression.
