How to Display Mathematical Symblos, Greek Letters etc in HTML

When i was writing a post, i found it difficult to display some mathematical symbols in the post. At last, i solved it and found that there are easy to remember mnemonics for most of the symbols we come across. Sometimes you can get them only from the 'charmap' (enter charmap in 'Run' in your windows OS). There are escape sequences in HTML which will help you to include mathematical symbols and other Greek letters which are often used as variables or notation for some processes. To display these symbols in a webpage, simple mnemonics or corresponding code can be used. These informations are directly available in HTML4.0 website.

Program to Understand Bitwise Operators

This program is to understand working of bitwise operators

#include<stdio.h>

main ()

{

unsigned int a = 60; /* 60 = 0011 1100*/

unsigned int b = 13; /* 13 = 0000 1101 */

printf ("a=60 ( 0011 1100)\nb=13 ( 0000 1101)\n"); 

int c = 0;

c = a&b ; /* 12 = 0000 1100 */

printf ("a&b=%d\n",c );

c = a | b ; /* 61 = 0011 1101 */

printf ("a|b=%d\n",c );

c = a ^ b ; /* 49 = 0011 0001 */

printf ("a^b=%d\n", c );

c = ~ a; /*-61 = 1100 0011 */

printf ("~a=%d\n" , c );

c = a << 2 ; /* 240 = 1111 0000 */

printf ("a<<2=%d\n" , c );

c = a >> 2 ; /*15 = 0000 1111*/

printf ("a>>2=%d\n" , c );

}
