Course Introduction:The difference between value passing and reference passing in C++: value passing creates a copy of the parameter and does not affect the original variable; reference passing directly operates the parameter, and the modification is reflected in the original variable. Practical case: exchanging two integer values. Passing by value will not exchange, but passing by reference will.

Course Introduction:C++ parameter passing methods are divided into value passing and reference passing. Passing by value creates a copy of the function parameters without affecting the original variables; passing by reference directly operates the original variables. The choice depends on your needs: protect the original variable using pass by value, modify the original variable or improve efficiency using pass by reference.

Course Introduction:The difference between Java value transfer and reference transfer: 1. Transfer of basic data types; 2. Transfer of objects; 3. Modification of reference pointing. Detailed introduction: 1. Transfer of basic data types. For basic data types, Java uses value transfer. When a variable of a basic data type is passed as a parameter to a method, the value of the variable is actually transferred, not the value of the variable. Its reference, which means that modifications to this parameter in the method will not affect the value of the original variable; 2. Transfer of objects, for object references, the situation is different, etc.
