What are pass by value and pass by reference
Article Introduction:Passing by value is to pass a copy of the parameter to the function, so the function receives a copy of the parameter value, not the parameter itself. Any modification to the parameter inside the function will only affect this copy and not the original variable. value. Pass by reference is to pass the address or reference of the parameter to the function. This means that the function receives a reference to the original data, not a copy of the data. Any modifications made to the parameters inside the function will directly affect the original data. These two delivery methods have their own applications, advantages and disadvantages in different programming languages and scenarios.
