Given is the task to show the working of forward_list assign() function in C++.A forward_list only keeps linkage with the next element unlike normal list that keeps linkage with the next as well as the preceding elements, which helps iterations in forward as well as backward directions. But forward_list can only iterate in the forward direction.The forward_list::assign() function is a part of the C++ standard template library. It is used to insert elements inside a forward list and if the list already contains some elements then they are replaced by the new ones that are added by the user. header ... Read More
Given the task is to show the working of const_cast in C++.const_cast is one of the type casting operators. It is used to change the constant value of any object or we can say it is used to remove the constant nature of any object.const_cast can be used in programs that have any object with some constant value which need to be changed occasionally at some point.SyntaxThe syntax is as follows −const_cast(expression)ExampleInput: x = 50 const int* y = &x cout

Given the task is to show the use of header file in C++.The header file is a part of the localization library which further is a part of the C++ standard library. Originally it was in the C standard library with the name as .The functions and declarations included in this header file are used for tasks that require date formats and currency symbols of different countries.The functions included in header file are setlocale() and localeconv()The macros that are defined in this header file and are used in these two functions are −LC_ALL-> It sets everything.LC_COLLATE-> It ...

Given the task is to show the working of cosh() function for complex numbers in C++.The cosh() function is a part of the C++ standard template library. It is a little different from the standard cosh() function. Instead of calculating the hyperbolic cosines of angles that are in radians, it calculates the complex hyperbolic cosine values of complex numbers.The mathematical formula for calculating complex hyperbolic cosine is −cosh(z) = (e^(z) + e^(-z))/zWhere, “z” represents the complex number and “i” represents the iota.The complex number should be declared as follows −complex name(a, b)Here, that is attached to the “complex” data ...

Given the task is to show the working of cos() function for complex numbers in C++.The cos() function is a part of the C++ standard template library. It is a little different from the standard cos() function. Instead of calculating the cosine of simple integral or rational numbers, it calculates the complex cosine values of complex numbers.The mathematical formula for calculating complex cosine is −cos(z) = (e^(iz) + e^(-iz))/2where “z” represents the complex number and “i” represents iota.The complex number should be declared as follows −complex name(a, b)Here, that is attached to the “complex” data type describes an object ...

Given the task is to show the working of copysign() in C++.The copysign() function is a part of the C++ standard template library. It takes two arguments and produces the result by combining the magnitude of the first value and the sign of the second value. or header file should be included to call this function.SyntaxThe syntax is as follows −copysign(x, y)ExampleInput: copysign(4, -5) Output: -4Explanation − The following example demonstrates how we can copy the sign of one value to the magnitude of another value. The sign of the second argument, that is “-“and the magnitude of the ... Read More
Isn’t it costly to buy mobile devices each time a new version comes up, to test your mobile applications? Off course, it is certainly a costly affair to keep acquiring those mobile devices physically as the new versions and operating systems are kept on releasing in regular intervals.But you cannot just stop purchasing the devices and restricts your testing to a certain limits, which surely gives your competitors an advantage to have a better functioning application than yours.Worried! No worries, every dark cloud have a silver lining You can test your mobile applications on as many devices of different versions ... Read More
Given is the task to show the working of list emplace() function in C++.The list::emplace() function is a part of the C++ standard template library. It is used to insert values inside a list at a specified position by the user. header file should be included to call this function.SyntaxList_Name.emplace(position, element)ParametersThis function takes two parameters −First is position, which represents the position at which the new element has to be placed and the second is value, which represents the element that has to be inserted inside the list at the position.Return ValueThe function returns an iterator that point at the ...
