  11. Symbols used in Writing Programs { opening curly bracket } closing curly bracket # hash sign or number sign (shift+3) ( ) small brackets “aaaa ” double quotes ‘ aaaa ‘ single quotes , comma ; semicolon void main( ) main function // is used for making comment in one line /* is used for making comment in block form */
