The dark side of running background processes is that they may expect to work with the standard input (or worse, read directly from the terminal). If a program tries to read something from the standard input when it’s in the background, it can freeze (try fg to bring it back) or t...
How does round Function work in C++? A round() function works mainly with an Argument value and it is a Static instance method, the value returned is the nearest int value which is originally assigned as float=3.3; So, the nearest value returned should be 3.0, not 3. Let’s talk Data...
pressing F2 might open your word processor or pressing F5 may refresh a web page. By having these functions already set up, you no longer have to remember complex commands in order to execute them. All you need to do is press the right function key once and the task will begin automatica...
This chapter is a guide to the Unix commands and utilities that will be referenced throughout this book. This is preliminary material, and you may ...
The following two compiler commands do most of the work of building the program: 在编译大多数.c文件时,你不会立即创建一个可执行文件。相反,可以在每个文件上使用编译器的-c选项来创建目标文件。 为了看清楚这是如何工作的,假设你有两个文件,main.c和aux.c。 下面的两个编译器命令完成了构建程序的大...
When you compile code that uses non static member functions, the compiler does a little bit of work behind the scenes. It translates calls like:myclassinst.myfun(); //where myclassinst is not a pointertomyfun(&myclassinst);and it translates calls like:...

() which will do the same job (albeit with slightly different syntax). Additionally, if you're dealing with URL commands which may contain variables used in a query string then both Python and JavaScript have dedicated library functions specifically designed to decode these types of strings into...
static y = 2; //static variable } 4. Automatic Variables Automatic variables are declared with the auto keyword. All the variables that are declared inside the functions are default considered as an automatic variable. Example is given as follows, ...
This C++ Sleep tutorial will discuss the Sleep Function in C++ & see how to put a thread to sleep. We will also learn about the other functions viz. usleep: Any computer program that is a process, task or thread may ‘sleep’ or go into an inactive state for a specific time. The ex...
