Data types are used to store various types of data that is processed by program. Data type attaches with variable to determine the number of bytes to be allocate to variable and valid operations which can be performed on that variable. C supports various data types such as character, integer and floating-point types. Character Data Type C stores character type internally as an integer. Each character has 8 bits so we can have 256 different characters values (0-255). Character set is used to map between an integer value and a character. The most common character set is ASCII. Let take a look at example of using a variable which hold character 'A'. #include  void main()  {  char ch = 'A';  printf("%c\n",ch);  ch = 65;                     // using integer representation  printf("%c\n",ch);  ch = '\x41';               // using hexadecimal representation ...

The C program is a set of functions. A C program always starts executing in a special function called main function. Here is the simple but famous "Hello World" program which prints "Hello World" greeting to screen. #include void main() { printf("Hello World!\n"); } The first line is the the #include directive. C program uses this directive to load external function library - stdio is c library which provides standard input/output. printf is a function which is declared in the header file called stdio.h The next is the main function - the first entry point of all C programs. C program logic starts from the beginning of main function to the its ending. And finally is the printf function which accepts a string parameter. The printf function is used to print out the message to the screen.

#include #include void main() { int a,b,c; a=10; b=25; printf("\nThe Value of A is %d",a); printf("\nThe Value of B is %d",b); c=a; a=b; b=c; printf("\nNow the Value of A is %d",a); printf("\nNow the Value of B is %d",b) ; getch(); }

When we use child Window in Silverlight its Automatically disable Background but its floatable so i want using child window float feature without disabling the background so i childwindow is top element on xmal so alway on top thats you can not access back button or any other control so i put childwindow in popup control and make popup on or off .
