The system was divided into two parts : Programs and services: It is the part readily apparent to users e.g. shell, mail text editor etc. Operating System: That supports above-mentioned programs and service.
Ensure Main Method Exit at the End
We can achieve this by isAlive() and join() methods of Thread class. isAlive() is not great at doing this task. So, we will be using join() method. Threadd class — implements Runnable : class Threadd implements Runnable{Thread t;String name; Threadd(){name = “how”;t = new Thread(this,name);System.out.println(“This is thread”);t.start();} public void run() {for(int i=0;i<20;i++){System.out.println(“This is run method”);try{Thread.sleep(100);}catch(InterruptedException
Things to note about Functions in C plus plus (C++)
While passing arguments, the function creates copies of the arguments passed to it. This type of passing arguments is called passing by value. We can pass structure as arguments. We can also return a structure. Useful while returning multiple values. Passing by reference : e.g. void intfunc(float& a, int& b); We can also pass structures
Things to note about Structure in C plus plus (C++)
Initializing structure structure_name variable_name = {value1,value2,…,valueN}; Initializing nested structure structure_name variable_name = { {value1, value2},{value3,value4}}; A structure can be nested up to any depth in theory. Structure can hold data and functions (In c they can only hold data) An enum declaration defines the set of all names that will be permissible values of the
Kernel Architecture of Various Popular Operating Systems.
