Arrays and Strings in C programming

By
          Array is a data structure that store a number of data items as a single entity (object). The individual data items are called elements and all of them have same data types. Array is used when multiple data items that have common characteristics are required (in such situation use of more variables is not efficient). In array system, an array represents multiple data items but they share same name. The individual data items can be characters, integers, floating point numbers etc. However, they must all be of the same type and the same storage class.
    It is the fact that a string can be represented as a one-dimensional character -type array. Thus, character array is also known as string. Each character within the string will be stored within one element of the array. Strings are used by C to manipulate text such as words and sentences. A string is always terminated by a null character ( i.e \0). The terminating null character \0 is important because it is the only way the string handling functions can know where the string ends.

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...

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...

BIOS

By
BIOS stands for Basic Input Output System. It is is kind of OS pre- attached in the system Design to detect every I/O devices It holds basic drivers -checks all I/O devices -Loads main OS -Responsible for starting System switched on manufactured by AMI,Phonix,award,Baiostar POST error test, boots trap load, BIOS is unintrusive system. CMOS and BIOS are two different components of the motherboard. CMOS work as storage if BIOS. A basic software program containing all BIOS is permanently stored in the ROM. every essencial holds program Tresh passing without knowinig is called intrusive.
