In this article we will be discussing the working, syntax and examples of std::is_unsigned template in C++ STL.is_unsigned is a template which comes under header file. This template is used to check whether the given type T is an unsigned type or not.What are unsigned data types in C++?Unsigned data types are those which we use knowing the values will not go in negative, like roll number, id of random numbers, etc.To make a type as unsigned we use keyword unsigned as prefix of the data type like −unsigned int;unsigned float;Syntaxtemplate is_unsigned;ParametersThe template can have only parameter of type ...

In this article we will be discussing the working, syntax and examples of std::is_signed template in C++ STL.is_ signed is a template which comes under header file. This template is used to check whether the given type T is a signed type or not.What is a signed type?These are the basic arithmetic types, which contains sign value with them. All arithmetic data types are either signed and unsigned.Like we want to show the values in negative we use signed type.Like: -1 is signed int and -1.009 is signed float.By default all the types are signed to make them unsigned ...

In this article we will be discussing the working, syntax and examples of std::is_pointer template in C++ STL.is_ pointer is a template which comes under the header file. This template is used to check whether the given type T is a pointer type or not.What is a Pointer?Pointers are non-static types which hold an address of another type or in other words which points to some memory location in the memory pool. With help of an asterisk (*) we define a pointer and when we want to refer the specific memory which the pointer is holding then also we ... Read More

In this article we will be discussing the working, syntax and examples of std::is_pod template in C++ STL.is_ pod is a template which comes under header file. This template is used to check whether the given type T is a POD(plain-old-data) type or not.What is POD(Plain old data)?Plain old data(POD) types are those types which are also in old C language. POD types also include scalar types. POD class type is that class type which is both, trivial (which can be initialised statically) and standard layout (which is a simple data structure like struct and union).Syntaxtemplate is_pod;ParametersThe template ...

In this article we will be discussing the working, syntax and examples of std::is_fundamental template in C++ STL.is_ fundamental is a template which comes under the header file. This template is used to check whether the given type T is a fundamental data type or not.What is Fundamental type?Fundamental types are the built-in types which are already declared in the compiler itself. Like int, float, char, double, etc. These are also known as built-in data types.All the data types which are user-defined like: class, enum, struct, references or pointers, are not part of the fundamental type.Syntaxtemplate is_fundamental;ParametersThe template ...

In this article we will be discussing the working, syntax and examples of std::is_final template in C++ STL.is_final is a template which comes under the header file. This template is used to check whether the given type T is a final class or not.What is a final class in C++?When we declare a class with the final specifier then it is called as Final Class. Final class is a special kind of class which can’t be extended to create another class. In C++ to make a class as a final we make a class as a friend and then ... Read More

The .NET centric applications are meant to windows operating system up till now, but now Microsoft has introduced a new cross-platform application called Mono which enables the execution of the application developed under the .NET platform in Linux environment by giving an impression in such a way that as if we are running Linux package rather than executing .exe file.MonoMono is an open-source utility that allows the developer to execute .NET centric applications on other platforms such as Mac or Linux as it provides an installation package for Windows platform to compile and execute .NET assemblies on Windows OS without ever ...

Suppose we have 3 positives numbers a, b and c. We have to find the minimum flips required in some bits of a and b to make (a OR b == c ). Here we are considering bitwise OR operation.The flip operation consists of change any single bit 1 to 0 or change the bit 0 to 1 in their binary representation. So if a : 0010 and b := 0110, so c is 0101, After flips, a will be 0001, and b will be 0100To solve this, we will follow these steps −ans := 0for i in range 0 ... Read More

Suppose we have a binary tree, we have to find the sum of values of nodes with even-valued grandparent. (A grandparent of a node is the parent of its parent, if it exists.). If there are no such nodes with an even-valued grandparent, then return 0. So if the tree is like −The output will be 18. The red nodes are nodes with even-value grandparent, while the blue nodes are the even valued grandparents.To solve this, we will follow these steps −Define a map called parentDefine a method called solve(), this will take node and parif node is null, then ...

Suppose we have one m * n matrix called mat and an integer K, we have to find another matrix answer where each answer[i][j] is the sum of all elements mat[r][c] for i - K
