What is UNIX and Linux?

By
1,  History of UNIX

=> UNIX is an Operating System (OS).

=> UNIX was developed about 40 years ago i.e., 1969 at AT&T Bell Labs by Ken Thompson and Dennis Ritche.

=> It is a Command Line Interpreter. v It was developed for the Mini-Computers as a time sharing system.

=> UNIX was the predecessor of LINUX.

 2. History of  LINUX

=> LINUX was created by Linus Torvalds in 1991.

=> LINUX is a open source.

=> LINUX is a variant of UNIX.

3.   Why LINUX/UNIX?

=> LINUX is free.

=> Can view and edit the source code of OS v It is fully customizable.

=> Most Important Feature is Stability

=> 30Years to get the bugs

=> Important in shared environments and critical applications

=> LINUX has better security structure.

=> High Portability.

=>Easy to port new H/W Platform.

=>Written in C which is highly portable

What is manipulator in C++?

By
Answer: Manipulators are special functions that can be included in the I/O statement to alter the format parameters of a stream. Table-2 shows some important manipulator functions that are frequently used. To access these manipulators, the file < iomanip.h > should be included in program.                               Table-2               Manipulators                                                    Equivalent ios function               set...

Explanation of Graphics in C programming

By
   The header file graphics.h should be included to use graphics related built in functions. Again, the variable gDriver is an integer variable that specifies graphics driver to be used. Device drivers are small programs which talk directly to the hardware. Graphics drivers are a subset of device drivers and are applicable only in the graphics mode. The initialization of this variable to DETECT is to set another variable gMode to the highest resolution available for the detected driver.  The value of this variable gDriver may be another than DETECT (e.g. 1 for CGA, 9 for VGA.). The variable gMode is an integer that specifies initial graphics mode.       The built in function initgraph() is for graphics initialization. The syntax for this is as   initgraph(&graphics_driver, &graphics_mode, path_to_driver);   path_to_driver specifies the directory path where initgraph() looks for graphics drivers ( .BGI files). Thi...

Passing arrays to functions in C programming

By
Like any other variables, we can also pass entire array to a function. An array name can be named as an argument for the prototype declaration and in function header. When we call the function no need to subscript or square brackets. When we pass array that pass as a call by reference because the array name is address for that array. /* Program to illustrate passing array to function */ #include<stdio.h> void display(int) ; /* function prototype */ main( ) { int num[5] = {100, 20, 40, 15, 33, i ; clrscr( ) ; printf (“\n The content of array is \n”) ; for (i=0; i<5; i++) display (num[i]) ; /*Pass array element fo fun */ getch{ } ; } void display(int n) { printf (“\t%d”, n ) ; } Output:     The content of array is 100      20       40       15 3 /* Program to read 10 numbers from keyboard to store these num into array and then c...
