It all depends on what you are making, if you want your own specific AI or some types of events or you simply want to make your game more diverse coding is highly recommended. Entities provided by cryengine are helpful but make for a bland game (usually). Take a look at the coding and give it a try

Nothing stops a member function from changing any of the values in a class. By convention, an accessor function is used to give read only access to class data, but that does not mean that it is prohibited from doing so. It is a member function, after all, and it has all the rights of any member function of the class.

An operand is the value that is being operated upon by an operator. For instance, the C++ increment operator (++) is a unary operator, which means it has only one operand, the variable that we wish to increment. This in the expression x++, x is the operand. The addition operator (+) is a binary operator and therefore has two operands. Thus in the expression x + y, x and y are the operands.

Yes. Without prototypes you must ensure all definitions are declared forward of their usage. This isn't always possible. Separating the prototypes from the definitions means you can #include the prototypes forward of their usage, and place the actual definitions anywhere you like.

There are two methods of casting one type to another: static casting and dynamic casting (both of which apply to pointers and references to objects). Statically casting a derived class to a base class is typesafe as the base class is guaranteed to exist if the derived class exists. However, static casting from a base class to a derived class is always considered dangerous as the conversion is not typesafe. Dynamic casting exists to cater for this scenario, however it is only possible when the base class is polymorphic (thus ensuring the required runtime information is available). If the conversion is not possible, the return value is NULL. However, it is considered bad programming practice to dynamically cast from a base class to a derived class. If the base class is polymorphic (which it must be), there is NEVER any need to dynamically cast between types. Virtual methods ensure correct behaviour. Whenever you are forced to dynamically cast from a base class to a derived class, consider redesigning the base class interface instead, as it is a clear sign of bad design. It is not dangerous, however; only static casting from a base class to a derived class is considered dangerous.

sum+=list[i];

return(sum);

}

Declaring member variables (data) private ensure only the class and friends of the class have access to an object's data.

Declaring member methods (functions) public is required to provide an interface to the private data.

Usually accessor and mutator methods (get/set methods) are declared public to allow user-interaction with the data. However the data itself must remain hidden by the accessors (returned by value) otherwise there's no point in hiding the data -- there is no control. Similarly, the mutators should allow the data to be modified through a controlled interface, thus ensuring the data remains in a valid state at all times. Again, allowing a public mutator to modify the data without validation defeats the purpose of hiding the data in the first place.

Protected access is another option. This is similar to private access, but also permits access to derived classes.

A well-designed class interface should only expose as much as it needs to, and no more. If an object cannot assure its own data integrity at all times, then it is no better than a structure, which is always public by default.

Note that the general rules on class interface design are intended to help not hinder you. Many new programmers find them too restrictive, often making members public when they should really be private. They have entirely missed the point of using a class rather than a structure. That is, a well-designed interface that fully encapsulates an object automatically enlists the help of the compiler to reduce the chances of you or a third party coder from attempting an illegal operation upon the data within the object. If the data integrity can be assured at all times, then the chance of error is greatly reduced. The more complex the data, the more important this becomes.

The only advantage is that it is free. But it is disadvantaged by the fact it only supports Windows 95, 98, NT and 2000. Thus it is not compliant with the current C++ standard, and is only useful for legacy development upon these Windows platforms.

If you mean an array where each element is a list, then the STL is your friend. To create an array of lists of any type T, use the following declaration:

std::vector<std::list<T>> my_array_of_lists;

All Intel processors can be used for C++ programming. All you need is a suitable compiler/linker.

With regards performance, the N450 does not perform well compared to modern netbook processors. Given its age this is hardly surprising.

A standardised language means that code becomes completely portable between any compiler, so long as the compiler supports the standard and the code itself does not contain compiler-specifics. In terms of game development, this makes it much easier to port games between platforms.

Of course, C++ code is usually far from standard because the standard does not include platform-specifics (in terms of hardware and operating system). Thus each platform requires it own set of libraries. Generic libraries are available to make things easier (such as OpenGL and OpenAL for graphics and audio), but Windows API calls vary greatly from Linux API calls, and each needs its own set of libraries. However, with prudent use of preprocessor definitions (macros) and helper functions, it is possible to write generic cross-platform code.

You can't overload the insertion operator (<<) from inside a class because the l-value must be an ostream object, but operator overloads implemented within classes always implicate the class instance itself as being the l-value.

You must overload the insertion operator from outside of the class, like so:

ostream& operator<<(ostream& lhs, const MyObject& rhs)

{

lhs << rhs.get_data();

return( lhs );

}

Yes, passing an array name to a pointer assigns the first memory location of the array to the pointer variable. An array name is the same as a pointer to the first location of the array, with the exception that an array name is a r-value, while a pointer is an l-value.

The simple argument for case-sensitivity is that character 'A' (#65) and character 'a' (#97) are not the same character. To us humans they are clearly the same letter, but computers are less forgiving. Back in the good old days when RAM and CPU time were expensive, it simply wasn't worth the effort or expense to have the computer treat them as being the same. In those days, the onus was largely upon the programmer to ensure they identified variables correctly. Programmers were far more concerned with speed of compilation and, having been brought up within the case-sensitive world of Unix, they were intelligent enough to know that MAX and max are not the same identifier as far as the computer was concerned.

As the cost of computing fell and more and more people wanted to program them, the unforgiving nature of case-sensitive programming became a greater concern, thus languages such as BASIC were developed to address the problem and make life easier for newcomers. The same can be said of DOS, from which MS-DOS evolved. But while these languages and operating systems are more forgiving, they lack the flexibility and speed of a case-sensitive environment.

In C, for instance, the inherent case-sensitivity makes it possible to use programming conventions such as all uppercase for macro identifiers and lowercase for C identifiers. Macros are not actually part of the C language -- they are used by the preprocessor to prepare the C source code for compilation -- but it is helpful to be able to differentiate a macro from an actual identifier in your code, even when they have the exact same name.

MAX and max are not the same, but then neither is Max or mAx. Normally you wouldn't use mixed-case like this in C, as it makes your code hard to read, but the language is flexible enough to permit it should you wish to do so. And that is the main advantage: flexibility. The main disadvantage is the lack of forgiveness. But if you want forgiveness, you wouldn't be programming in C to begin with, you'd use something far more abstract instead, like Visual Basic.

In linked queue we're dynamically allocating the memory and there's no fixed memory limit in Linked Queue. That's why there's no operation for overflow.

I guess It's the correct reason

A basic shell program should essentially emulate a command prompt with a very limited set of commands, such as exit to close the shell and possibly cd to change the current directory. Shell's are typically used to spawn other processes, but a basic shell will typically limit which processes may be allowed to run.

Use an associative container such as std::set and enumerate in reverse order, or supply a predicate that sorts in descending order such as std::greater<T> (default is std::less<T>).

There is no requirement for any statement in a C++ function, let alone three sets of statements. For instance, the following is a perfectly valid function:

void foo(){}

Clearly this does nothing as it has no statements in the function body, but it is nevertheless a valid function.

Perhaps you mean something else by "statements". The only requirement of a function is that it have a return type, a valid name, an argument list and a function body. The return type may be void, of course, and the argument list may be empty, but it must include the ellipses. The function declaration need not include the function body, and the argument list need only specify the type of argument (the argument names are optional and need not match those declared in the actual definition).

The function name and the arguments define the function signature (the prototype), thus the three required "components" of a function are the return type, the signature and the function body.
