Operators in C programming : Conditional Operators

By
  The operator ?: is known as conditional operator. Simple conditional operations can be carried out with conditional operator. An expression that make use of the conditional operator is called a conditional expression. Such an expression can be written in place of traditional ifelse statement.
A conditional expression is written in the form:
expression1 ? expression2 : expression3

When evaluating a conditional expression, expression1 is evaluated first. If expression1 is true, the value of expression2 is the value of conditional expression. If expression1 is false, the value of expression3 is the value of conditional expression.
For example:
a = 10 ;
b = 15 ;
x = (a > b) ? a : b ;
In this example, x will be assigned the value of b. This can be achieved by using the if_else statement as follows:
if (a<b)
x = a ;
else

x = b ;

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.
