C – Operator precedence and Associativity1 min read

What are Precedence and Associativity?

Precedence and Associativity are the rules that are used to determine the operators with the highest priority in evaluating an equation that contains different operations.

For example: x = 10 + 5 * 2;

In this example, x is assigned as 20, not 30 that’s because operator * has higher precedence than +, and hence it first gets multiplied (5*2), and then the result is added to 10.
