Question
In Ada, declarations of named constants have the option of omitting the type of the constant, as illustrated by the following examples: N: Constant Integer:= 100; -- Type of constant is specified N: constant:= 100; -- Type of constant is omitted (a) Are both kinds of declarations allowed for all constants, or are there any cases where only one kind is allowed? (b) What differences are there, if any, in what expressions are allowed as the value of a constant? (c) What differences are there, if any, in how the constants can be used?Explanation / Answer
In Ada programming when creating constant, if the value is number, no need to specify data type. Once constant has created, we cannot assign new value to variable. Any type of variable can be created as a constant and as long as we assign value when declaring it. A constant is value that doesn't change and to create a constant, use the constant keyword.
Therefore both the declaration are correct and shows the value of N = 100.
