Recursion is a technique where we call a function from the same function itself. There must be some base or terminating condition to end the recursive call. Recursive procedures are very much helpful to perform complex iterative solution with fewer codes and easier solution approach through sub-operation finding. In this article we shall discuss a recursive approach to perform product (multiplication) between two numbers in C++. Initially we will understand the basic principle, the syntax for recursive function call, the algorithm and the source code. Multiplication using Recursion In high-level languages, there is the multiplication operators available to directly perform ... Read More

Static typing is used in the C++. Variables must be defined with a specific type in order to write programmes. Inputs from the console or files must occasionally be read. In this case, the programme is given the string data. Special operations are necessary to transform them into other datatypes. This article will provide the C++ method for converting strings to floating point integers. A couple different methods can be used to accomplish this. Explore each of them separately. Using stringstream in C++ Streams are a fantastic tool in C++. Filestreams, standard input/output streams, etc. are examples of these streams. ... Read More

C++ is a statically typed language. To write programs we need to define variables of specified types. Sometimes we need to read inputs from the console or files. In such a scenario the string data are read into the program. To convert them into other datatypes needs special operations. In this article, we shall discuss how to convert strings to integers in C++. There are a few different techniques to do so. Let us explore them one by one. Using stringstream in C++ C++ uses streams for different applications. Such streams are filestreams, standard input/output streams, etc. There is another ... Read More

The hyperbola, rather than the circle, is used to define hyperbolic functions. It returns the ratio parameter for the hyperbolic tangent function based on the supplied radian angle. On the contrary, however. To calculate the angle from the hyperbolic-tangent value, inverse hyperbolic trigonometric procedures like the hyperbolic arctangent operation are required. This article will demonstrate how to utilize the C++ hyperbolic inverse-tangent (atanh) function to determine the angle using the hyperbolic tangent value, in radians. The hyperbolic inverse-tangent operation has the following formula − $$\mathrm{cosh^{-1}x\:=\:\frac{1}{2}In\left(\frac{1\:+\:x}{1\:-\:x}\right)}, where \:In\: is\: natural\: logarithm\:(log_e \: k)$$ The atanh() function The angle can be calculated ...
