This is an important step, since the same number can mean absolutely different things (and replaced with different constants, as the case may be). If yes, replace the number with your constant. In this case, you should use one of the refactoring methods to avoid type code:ĭeclare a constant and assign the value of the magic number to it.įor each of the numbers that you find, double-check that the magic number in this particular case corresponds to the purpose of the constant. Say that you have two types of users and you use a number field in a class to specify which is which: administrators are 1 and ordinary users are 2. If the single digit comes out to be 1,then the number is a magic number. Note: This C Program To Print Magic Numbers has been compiled with. A number is said to be a magic number, if the sum of its digits are calculated till a single digit recursively by adding the sum of the digits after every addition. Must Read: C Program To Find Sum of Two Complex Numbers. A magic number is defined as a number which can be expressed as a power of 5 or sum of unique powers of 5. Amongst these, 2, 8, 20, 28, 50, and 82 corresponds to the number of protons, while 126 is the only known magic number associated with neutrons. Reverse the Digits of A and store it in B. The seven most widely recognized magic numbers are 2 (helium), 8 (oxygen), 20 (calcium), 28 (nickel), 50 (tin), 82 (lead), and 126 (hypothetical unbihexium). Magic numbers are sometimes used as type code. Find Sum of Digits of the Original Number and store it in A.

Instead, use the standard method for getting the collection length. The no-magic-numbers rule aims to make code more readable and refactoring easier by ensuring that special numbers are declared as constants to make their. PNG files provide high quality vector and bit.

For example, if you have a magic number that signifies the number of elements in a collection, you don’t need to use it for checking the last element of the collection. If we scan a disk and find this signature, it may thus be an Illustrator file.
