This binary technique is really no different than how computers normally compute integer powers. However, the fact that we can break the process down to successive multiplications allows us to apply the modulus at every step of the way.
This can be a problem when porting case sensitive C code into Ada. Another thing to watch for in Ada source is the use of ' the tick. The tick is used to access attributes for an object, for instance the following code is used to assign to value s the size in bits of an integer. This can also be applied to arrays so if you are passed an array and don't know the size of it you can use these attribute values to range over it in a loop see section 1.
The tick is also used for other Ada constructs as well as attributes, for example character literals, code statements and qualified expressions 1. Integer; a, b, c: However the fourth example in C leaves k undefined and creates l with the value 1.
In the Ada example it should be clear that both k and l are assigned the value 1. Another difference is in defining constants.
Before we delve into descriptions of the predefined Ada types it is important to show you how Ada defines a type.
Ada is a strongly typed language, in fact possibly the strongest. This means that its type model is strict and absolutely stated. The important keyword is new, which really sums up the way Ada is treating that line, it can be read as "a new type INT has been created from the type Integer", whereas the C line may be interpreted as "a new name INT has been introduced as a synonym for int".
This strong typing can be a problem, and so Ada also provides you with a feature for reducing the distance between the new type and its parent, consider subtype INT is Integer; a: The most important feature of the subtype is to constrain the parent type in some way, for example to place an upper or lower boundary for an integer value see section below on ranges.
We have seen above the Integer type, there are a few more with Ada, these are listed below. Any Ada compiler must provide the Integer type, this is a signed integer, and of implementation defined size.
Unsigned Integers Ada does not have a defined unsigned integer, so this can be synthesised by a range type see section 1. This means that if you have a modular type capable of holding values from 0 toand its current value isthen incrementing it wraps it around to zero.
Contrast this with range types previously used to define unsigned integer types in section 1. Such a type is defined in the form: There is an Ada equivalent of the C set of functions in ctype.
As in C the basis for the string is an array of characters, so you can use array slicing see below to extract substrings, and define strings of set length. What, unfortunatly, you cannot do is use strings as unbounded objects, hence the following. One way to specify the size is by initialisation, for example: For parameter types unconstrained types are allowed, similar to passing int array in C.
To overcome the constraint problem for strings Ada has a predefined package Ada. Unbounded which implements a variable length string type. Ada has two non-integer numeric types, the floating point and fixed point types. A new Float type may be defined in one of two ways: The second line asks the compiler to create a new type, which is a floating point type "of some kind" with a minimum of 5 digits of precision.
This is invaluable when doing numeric intensive operations and intend to port the program, you define exactly the type you need, not what you think might do today. If we go back to the subject of the tick, you can get the number of digits which are actually used by the type by the attribute 'Digits.
So having said we want a type with minimum of 5 digits we can verify this: Each element, accuracy, low-bound and high-bound must be defined as a real number.Task.
