The parent-child process is described earlier if multiple processes attempt to process the shared data. The final result depends on the order in which the process is run, and it is assumed that a competitive relationship has occurred. Take a look at

The programming implementation of the greatest common divisor of two positive integers requires that the computational greatest common divisor be implemented with a function fun (int a,int b).#include void Main (){int n,a,b;int fun (int a,int

In the process of software development, it is often necessary to allocate and revoke the memory space dynamically, such as inserting and deleting nodes in the dynamic list.new int; //开辟一个存放整数的存储空间，返回一个指向该存储空间的地址（即指针）。new int(100); //指定该整数的初值为100new
