is_arithmetic Template in C++
In this article we will be discussing the working, syntax and examples of std::is_arithmetic template in C++ STL.is_arithmetic template helps to check whether the given class T is of arithmetic type or not.What is an Arithmetic Type?Arithmetic type consists of two types, that areintegral types − In this we define the whole numbers. The following are the type of integral types −charboolintlongshortlong longwchar_tchar16_tchar32_tfloating point types − These can hold fractional parts. The following are the type of floating point.FloatDoubleLong doubleSo, template is_arithmatic checks the defined type T is an arithmetic type or not and returns true or false accordingly.Syntaxtemplate ...
Read Morescalbn() function in C++
In this article we will be discussing the working, syntax and examples of scalbn() function in C++ STL.What is scalbn()?scalbn() function is an inbuilt function in C++ STL, which is defined in the header file. scalbn() function is used to scale significantly using the floating point base exponent.Significand is a part of a floating-point number consisting of its significant digits, depending upon the interpretation of the exponent significand can be an integer or a fraction.The function calculates the product of num and FLT_RADIX to the power n, where FLT_RADIX is the base of all floating point data types and ...
Read Moremktime() function in C++ STL
In this article we will be discussing the working, syntax and examples of mktime() function in C++ STL.What is mktime()?mktime() function is an inbuilt function in C++ STL, which is defined in the header file. mktime() function is used to convert the local time to and object time_t.This function is like the reverse of the function localtime(), which converts an input to the local timezone of the machine.This function automatically modifies the values of the member timeptr if they are off the range or there is tm_day and tm_yday which are not allowed.Syntaxtime_t mktime( struct tm* tptr );ParametersThe function ...
Read Moreis_scalar template in C++
In this article we will be discussing the working, syntax and examples of std::is_scalar template in C++ STL.is_scalar is a template which comes under header file. This template is used to check whether the given type T is a scalar type or notThis template is a combination of is_arithmetic, is_pointer, is_enum, is_member_pointer or is_same and checks whether either if either one is true, the result of is_scalar will also be true.What is a scalar type in C++?A scalar type is that object which is neither a class type nor an array type. A scalar type is a type which ...
Read Moreis_trivial function in C++
In this article we will be discussing the working, syntax and examples of std::is_trivial template in C++ STL.is_trivial is a template which comes under header file. This template is used to check whether the given type T is a trivial class or notWhat is a trivial class type in C++?We say a type as a Trivial type, when its data is stored in a contiguous manner and which accepts only static default initialization. It can include arrays of any type, classes and scalar type.Trivial class is a class which is trivially default constructed and trivially copyable. There are some ...
Read Morequick_exit() function in C++ with Examples
In this article we will be discussing the working, syntax and examples of quick_exit() function in C++ STL.What is quick_exit()?quick_exit() function is an inbuilt function in C++ STL, which is defined in the header file. quick_exit() function is used to quickly terminate the calling process means it terminates the process without cleaning of its resources.This function is used for normal termination and no additional cleanup tasks are being performed like, no object destructors are called, whereas the C streams are closed or flushed, the files which are opened with tmpfile are being removed.When we terminate a process using quick_exit() ...
Read Moreis_polymorphic template in C++
In this article we will be discussing the working, syntax and examples of std::is_polymorphic template in C++ STL.is_polymorphic is a template that comes under the header file in C++. This template is used to check whether the class is a polymorphic class or not and return the result either true or false accordingly.What is a polymorphic class?A class which declares the virtual function from an abstract class where the virtual function is declared. This class have the declaration of the virtual function declared in other class.Syntaxtemplate is_polymorphic;ParametersThe template can have only parameter of type T, and check whether ...
Read MoreQuickly merging two sorted arrays using std::merge() in C++ STL(cute ho ap)
In this article we will be discussing how we can quickly merge two sorted arrays using std::merge() function in C++ STL.So, before solving the problem let's first discuss the std::merge() in C++ STL.What is std::merge()?std::merge() function is an inbuilt function in C++ STL, which is defined in the header file. merge() is used to merge two sorted ranges or series. This function combines two sorted ranges to make one single sorted range. All the elements are compared using less than operator (
Read Moreis_reference Template in C++
In this article we will be discussing the working, syntax and examples of std::is_reference template in C++ STL.is_reference is a template which comes under header file. This template is used to check whether the given type T is a reference type or not.This template is a combination of is_rvalue and is_lvalue and checks whether either if one is true, the result of is_reference will be also true.What is a reference in C++?A reference is an alias or another name of the already existing variable. A reference is different from pointer −As we cannot set a reference as null but ...
Read MoreSet cbegin() and cend() function in C++ STL
In this article we are going to discuss the set::cend() and set::cbegin() functions in C++ STL, their syntax, working and their return values.What is Set in C++ STL?Sets in C++ STL are the containers which must have unique elements in a general order. Sets must have unique elements because the value of the element identifies the element. Once added a value in set container later can’t be modified, although we can still remove or add the values to the set. Sets are used as binary search trees.What is set::cbegin():cbegin() function is an inbuilt function in C++ STL, which is defined ...
