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++.
