Overview of Project
Templates are a feature of the C++ programming language that allows
functions and classes to operate with generic type. This allows a function or
class to work on many different data type without being rewritten for each
one.
The C++ standard library provides many useful functions within a framework of
connected templets.
There are three kinds of tamplets:
1. Function templets
2. Class templates and
3. Since C++14, Variable templets.
Science C++11,templates may be either variadic or non-variadic; in earlier
versions of C++ they are always non-variadic.
Specialization
When a function or class is instsntiated froam a template,a specialization
Of that template is created by the compiler for the set of arguments used, and
the specialization is referred to as being a generated specialization.
Benefits/Advantage:
Templates and type-safe.
They are generally considered as an improvement over macro for the
purposes.
Templates avoid some common errors that make heavy use of function-
like macros.
Disadvantage:
Many compilers do not support nesting of templates.
When templates are used,all codes exposed.
Some compilers have poor support of templares.
Code quality and sustainability.
Profile of Problem Assigned
There are certain problems assigned.
Uniformity:
Usually, a finished template is so cheap because it is supposed to sell
hundreds of times. Template designers also make sure to get as clode to
the taste of the masses as possible. That’s why templates test to be very
conformable.
Restricted adaptability:
On top of that, every template has its limits when it comes to adjustability
and expandability. In any case, you have to try to make your needs clear
in advance; this is best done in the from of a chec-klist. With this
checklist, you can go out in your search for a new template.
Brand compatibility:
if a finished template doesn’t fully support your brand, the only possible
result is a compromise. However, You shouldn’t make compromises
when it comes to your web presence. After all , internet visitors only
knows you from website.
You could be a midsize entrepreneur with 400 workers and a fantastic
reord. Thus; finished templates can only be an option for a brand is veryc
exceptional case.
System Requirements
There are two types of system Requirements:
1. Hardware Requirement
2. Software Requirement
1.Hardware Requirement: The hardware requirements are the
requirements of a hardware device. Most hardware only has operating
system requirement or compatibility.
2.Software Requirement: The software requirements are description of
features and functionalities of the target system. Requirements convey the
expectations of users from the software product.
Hardware Requirement
Minimum requirement
1. Processor->At least a 4 core.
