Operator Precedence and Associativity

C Programming supports wide range of Operators . While Solving the Expression we must follow some rules , Example : while Solving the expression [ a + b *c ] , we should first perform Multiplication Operation and then Addition . Similarly in order to solve such complicated expression you should have hands on Operator Precedence and Associativity of Operators. Precedence of the Operator are Listed in the Following Table and This Table is Summarized in decreasing Order of Priority i.e Topmost Operator has Highest Priority and Bottommost Operator has Lowest Priority.

Notes :

1. Comma Operator Has Lowest Precedence .
2. Unary Operators are Operators having Highest Precedence.
3. Sizeof is Operator not Function .
4. Operators sharing Common Block in the Above Table have Equal Priority or Precedence .
5. While Solving Expression , Equal Priority Operators are handled on the basis of FIFO [ First in First Out ] i.e Operator Coming First is handled First.
