![]() In addition, a debugger may be able to print values of enumeration variables in their symbolic form. Nevertheless, enumeration variables offer the chance of checking and so are often better than #defines. Enumerations provide a convenient way to associate constant values with names, an alternative to #define with the advantage that the values can be generated for you.Īlthough variables of enum types may be declared, compilers need not check that what you store in such a variable is a valid value for the enumeration. Values need not be distinct in the same enumeration. Names in different enumerations must be distinct. If not all values are specified, unspecified values continue the progression from the last specified value, as the second of these examples:Įnum escapes Now in some cases you absolutely have to use the modulus operator. ![]() As a result it’s hardly surprising that code that uses the modulus operator can take a long time to execute. In other words the modulus operator is functionally equivalent to three operations. As every number can be represented in base 2 (0 or 1), represent the quotient in binary form by using the shift operator as given below: Determine the most significant bit in the divisor. The divisor and dividend can be written as. The first name in an enum has value 0, the next 1, and so on, unless explicit values are specified. Well a little thought shows that C A B is equivalent to C A B (A / B). Efficient Approach: Use bit manipulation in order to find the quotient. Read further to know about it.Īn enumeration is a list of constant integer values, as in C does not have an operator for exponentiation. modulus, computes the remainder from a division, this is defined for integer data types only. ![]() Note there is only one division operator for both integer and floating point division. + addition - subtraction multiplication / division. One such concept is of enumeration data type in C. C++/C has the following standard arithmetic operators. With advancement in learning to program one encounters many new concepts, remember to all this new concepts were designed to solve complexity of programming.
