What is the difference between the 4th and 5th lines?
int main()
{
int a = 3, b = 5, c, d;
c = a, b;
d = (a, b);
printf("c=%d d=%d", c, d);
return 0;
}
Output:
c=3 d=5

3The comma operator `,` has lower precedence than assignment `=`, meaning the first statement is parsed as `(c = a), b;`. – John Kugelman Mar 13 '21 at 07:06

[C Operator Precedence](https://en.cppreference.com/w/c/language/operator_precedence) will also help. – David C. Rankin Mar 13 '21 at 07:06
