Operator Precedence


Tutorials Cpp

Topic

What is Operator precedence in C++?



Explanation
Precedence of Operators:

An Operator Precedence is the hierarchy in which operators are evaluated. For example in the expression 2 + 2 * 3, the result would be 8 since the "*" operator has higher precedence over the "+" operator.

Now the same expression is used with a paranthesis like (2 + 2) * 3, the result would be 12. The "()" is used to force precedence by making the expression inside the braces executed first. If the precedence are equal then the associativity is used to evaluate an expression.

This is the Operator Precedence in C++.
