# C Operators Precedence and Associativity

### C Operators Precedence

When more than one operator is written together in the statement used in the program, then it is necessary to know Which calculation is being done first and which calculation is being done after and which calculation is being done from right to left, or which calculation is being done from left to right.

To make it clear, a table is given below which explains the priority and associativity of the operators -
