What is meaning of opreators in cpp
What is the purpose of the % operator in C++?
The % operator is used to find the modulus or remainder of a division operation.
What is the difference between the ++ and ++= operators in C++?
The ++ operator is used to increment a value, whereas the ++= operator is used to increment a value and assign it to another variable.
What is the purpose of the sizeof operator in C++?
The sizeof operator is used to return the size of a type or variable.
What is the significance of operator precedence in C++?
Operator precedence determines the order of operations in an expression, and can be changed using parentheses.
What is the purpose of the const_cast operator in C++?
The const_cast operator is used to perform a const cast, which allows modifying a constant variable.

Operator Precedence
- Operators have a specific precedence, which determines the order of operations
- Parentheses can be used to change the order of operations
