1. Swap is a part of the STL and later becomes an important spine of the exception-safe programming (Exception-safe programming) (see Clause 29), the SWAP function template definition for the standard library is similar to the following:namespace std{ template swap (t lhs,t rhs) { T temp (LHS); LHS=RHS; RHS=temp;} }View CodeAs long a

In Java, there is only one way to pass the parameters of the method: value transfer. Passing a value is to pass a copy (replica) of the actual parameter value into the method, and the parameter itself will not be affected.

SWAP is called a SWAP zone, which is equivalent to the virtual memory in Windows. Its function is to increase the memory through SWAP when the memory in our system is insufficient. When we install the Linux system, the root and SWAP are the most basic partitions. If we set SW... S
