Ambiguity in Function Overloading

Ambiguity in Function Overloading When the compiler could not choose a function between two or more overloaded functions , the situation is called as an ambiguity in function overloading . When the program contains ambiguity , the compiler will not compile the program. We know that compiler will decide which function to be invoked among the overloaded functions. When the compiler could not choose a function between two or more overloaded functions, the situation is called as an ambiguity in function overloading. When the program contains ambiguity, the compiler will not compile the program. The main cause of ambiguity in the program · Type conversion · Functions with default arguments · Functions with a pass by reference Type conversion #include <...

Templates

Templates in C++ The keyword template is used to define the function template and class template. It is a way to make your function or class generalize as far as the data type is a concern. The template is a simple and yet very powerful tool in C++. The simple idea is to pass data type as a parameter so that we don’t need to write the same code for different data types. For example, a software company may need sort() for different data types. Rather than writing and maintaining the multiple codes, we can write one sort() and pass data type as a parameter. C++ adds two new keywords to support templates: ‘template’ and ‘typename’ . The second keyword can always be replaced by the keyword ‘class’. Function template is also known as the generic template. template<class type> type func_name(type arg1, ...); Normal Example: __________________________________ #include<iostream.h> #include<conio.h> int big (int a, int b) ...

Programming Paradigms

Programming Paradigms A programming paradigm is a model of programming based on distinct concepts that shape the way programmers design, organize and write programs. A multi- paradigm programming language allows programmers to choose a specific single approach or mix parts of different programming paradigms . Paradigm can also be termed as a method to solve some problem or do some task. A programming paradigm is an approach to solve the problem using some programming language or also we can say it is a method to solve a problem using tools and techniques that are available to us following some approach. There are lots for a programming language that are known but all of them need to follow some strategy when they are implemented and this methodology/strategy is paradigms. Apart from varieties of programming language, there are lots of paradigms to fulfill each and every demand. They are discussed below: 1. Imperative Programming Pa...
