A function overload is a function that has more than one implementation. Each implementation must have a unique function signature, only the name remains the same, however functions cannot differ by return type alone.
Many overloads can be implemented as template functions, where the only difference is the type or types being operated upon. Manual overloading is typically required when the number of arguments differ. Generally, we try to implement function overloads such that one overload provides the implementation for the general case, while all others are expressed in terms of the general case. Where this may result in a loss of efficiency, we generalise as much as is possible and provide a limited number of specialised implementations to cater for exceptional cases.
As a typical example, to find the largest of any two values of the same type, regardless of the type, we can use a template function:
template<typename T>
const T& largest (const T& a, const T& b) {
return a>b?a:b;
}
This function provides the general case. From this we can provide specialisations, such as an overload to cater for three arguments which can be expressed directly in terms of the general case:
template<typename T> const T& largest (const T& a, const T& b, const T&c) {
return largest (largest (a, b), c);
}

Why use new and delete operator overloading in c plus plus?
one reason to use new and delete operator overloading in c++ is when you are using your own memory manager code. when the user of your code calls the new keywork, your memory manager code can allocate memory.
Why do you use of operator overloading in c?
Overloading, Overriding, Polymorphism, Information Hiding, Inheritance all these are CONCEPTS of C++ and Java. An Object Oriented Language and not of C language. Thats why Bjarne Stroustrup came up with C++ ...
How you use stack in c plus plus classes?
It would be easier to manipulate the stack in assembly language rather than C++.
What computer language java or C plus plus should you use to design an app for the ipod or should i use a software?
You would use neither Java nor C++, you would use Objective-C, in conjunction with the Apple iPod API (iPod Library Access).
What is function overloading in c language of computer?
There is no such thing as function overloading in C; that is a feature of C++. Function overloading allows us to provide two or more implementations of the same function. Typically, we use function overloading so that the same function can cater for different types. For instance, we might provide one implementation that is optimised to handle an integer argument while another is optimised to handle a real argument. We can also use function overloading to provide a common implementation of a function which can then be invoked by overloads that handle the low-level type conversions.

Is it possible to do operator overloading in c?
No. Operator and/or function overloading is only a C++ thing.
Why should you have to use comparison operator overloading in pairs in c?
You cannot overload operators in C. This is a C++ thing only.
How the turbo c plus plus use in the computer?
How the turbo c plus plus use what in the computer.
How you use stack in c plus plus classes?
It would be easier to manipulate the stack in assembly language rather than C++.
C coding for operator overloading?
C does not support operator overloading. If you mean C++ operator overloading, it depends on exactly what you wanted to do. If you wanted to '+' to strings, then you could write: string operator+(string a, string b) { // do something }

What is the c plus plus program to calculate the area of a circle using function overloading?
Function overloading is used when you want to re-use the same function name with different argument types or a different number of arguments. Calculating the area of a circle isn't the sort of function that requires overloading since the only argument you need is the radius. double area_of_circle (const double radius) { const double pi=4*atan(1); return pi*radius*radius; }
How do you use conioh header in c plus plus?
just as you do it in C.
Why do you use a different extension for c and c plus plus programs?
Simply because they're different languages, C++ has a few more added components to it. If they were the same they would both be C wouldn't they?
