Hello Everyone,
How are you? In C Programming how associativity of operators are implemented. I mean how to identify left operand is unambiguous and right operand is unambiguous????

for example,

int on,act=1,ink=4;
float tig=3.2;
on=ink*act/2+3/2*act+2+tig;

If I evaluate this expression manually, I am getting different answer. I f evaluate using C compiler I am getting different answer. Anybody can help me???????????

Do you mean order of operations.
()
*
/
+
-

Yes. If the expression doesn't contain paranthesis and two equal priority operators come next to next how system will execute the expresson.

For Example,


int on,act=1,ink=4;
float tig=3.2;
on=ink*act/2+3/2*act+2+tig;

ink*act/2 and 3/2*act

This is something that has never come up for me. I always teach to use parenthesis explicitly. That said, I belive its just left to right for equal priority operators.
