C Programming – Preprocessors The C Preprocessor is not a part of the compiler, but is a separate step in the compilation process.

A method name “unique” is coded with the return type as Boolean (true or false). So it will return “true” if its is a unique word, else it will return “false” if it is not unique. The method is done based on Linear Search Algorithm, we search for a character in a word, Once with first letter and then second, gradually with all the letters present in the word. For each phase of search we keep a counter,if the counter is increased more than once then the word is not unique, we stop further check and return “false”, from the method to the Main method. After all the letters searched, if the counter still remains < 2 then we say its unique.
Chemical Properties of Ethyne Ethyne (acetylene) Colourless, flammable gas (C2H2), manufactured by cracking of petroleum fractions. The simplest alkyne, it is explosive if mixed with air. When burned with oxygen, it produces extremely high temperatures up to 3480°C (6300°F) and is used in oxyacetylene torches. It is polymerized to manufacture plastics, synthetic fibres, resins and […]
