The acos() function returns the inverse cosine of an angle given in radians. It is an inbuilt function in C++ STL.The syntax of the acos() function is given as follows.acos(var)As can be seen from the syntax, the function acos() accepts a parameter var of data type float, double or long double. The value of this parameter should be between -1 and 1. It returns the inverse cosine of var in the range of -pi to pi.A program that demonstrates acos() in C++ is given as follows.Example Live Demo#include #include using namespace std; int main() { double d = ...

The atan2() function returns the tangent inverse of the coordinate in terms of y and x. Here y and x are the values of the y and x coordinates respectively. It is an inbuilt function in C++ STL.The syntax of the atan2() function is given as follows.atan2(dataType var1, dataType var2)As can be seen from the syntax, the function atan2() accepts two parameters var1 and var2 of data type float, double or long double that are y and x point respectively.The value returned by atan2() is in the range of -pi to pi and is the angle between the (x, y) ...

Use the loop attribute to specify that the audio/ video will start over again. You can try to run the following code to implement loop attribute −Example Your browser does not support the video element.
Constructors are functions of a class that are executed when new objects of the class are created. The constructors have the same name as the class and no return type, not even void. They are primarily useful for providing initial values for variables of the class.The two main types of constructors are default constructors and parameterized constructors. Details about these are given as follows.Default ConstructorsDefault constructors do not take any parameters. If a default constructor is not provided by the programmer explicitly, then the compiler provides a implicit default constructor. In that case, the default values of the variables are ... Read More
