"One of the methods used by statists to destroy capitalism consists in establishing controls that tie a given industry hand and foot, making it unable to solve its problems, then declaring that freedom has failed and stronger controls are necessary." --Ayn Rand
thank you for your reply...hey i have another doubt too..i declared a character pointer....
when i assign a value i.e .. a string to a character pointer using gets()...i get the warning possible use of that 'character pointer'before declaration..but the program works :rolleyes: ...do you know why?
