In modern programming languages we work with signed numbers and unsigned numbers also. For signed numbers the numbers can be positive or negative or zero. To represent negative numbers, the systems store the numbers in 2’s complement method. In this article we shall discuss how to determine a given number is positive, or negative in C++. Checking using if-else conditions The basic sign checking can be done by using if else conditions. The syntax for the if-else conditions is like below − Syntax if { perform action when condition is true } else { ... Read More
Gray codes or reflected binary codes are a special type of binary representation of numbers in which two successive values differ in only one bit. For example, the binary equivalent of 1 and 2 are 01 and 10, here two bits are changing. But in gray code, the 1 is 01 and 2 is 11, only one bit is changing. In this article, we will see how we can convert a given binary number into its gray code equivalent by using recursion in C++. Passing number as a decimal integer In the first example, we are providing the number in ... Read More
Any programming language that uses functions has code that is simpler, more modular, and simpler to change while being debugged. Functions are a remarkably beneficial component in a modular piece of code. A function's ability to accept arguments and output results. It is not necessarily necessary for a function to accept inputs and to always produce a result. There are numerous instances where functions only take a few inputs and don't return anything. does not always respond and will not tolerate disputes. This article will explain how to create C++ programmes that use functions, which accept a number of arguments ... Read More
Functions in functional programming are used to create modular codes. We construct submodules in many applications to make our code simple to write, simple to debug, and also efficient by avoiding writing needless code repeatedly. Functions have a role in achieving these traits. Functions frequently take arguments and produce a result. It occasionally might not accept any arguments but still produce something. There are several rare circumstances when functions take a few inputs but don't return anything. This course will discuss C++ methods that accept arguments but nothing is returned. Function with arguments but no return value To define a ... Read More
Functions in programming languages are used to make codes modular. In many applications, we create sub-modules to make our code easy to write, easy to debug, and also optimized by rejecting unnecessary code again and again. To achieve these features, functions come into the picture. In many cases, functions take arguments and return something. Sometimes it may not take any argument but returns something. Some special cases are also there when the functions do not take any arguments and do not return anything. In this tutorial, we shall cover such functions without argument and return value in C++. Function without ... Read More
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
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 ...

Similar to regular trigonometric functions, hyperbolic functions are defined using the hyperbola rather than the circle. From the specified radian angle, it returns the ratio parameter in the hyperbolic cosine function. But, to put it another way, to do the opposite. Inverse hyperbolic trigonometric operations like the hyperbolic arccosine operation are needed to determine the angle from the hyperbolic-cosine value. To calculate the angle using the hyperbolic cosine value, in radians, this tutorial will show how to use the C++ hyperbolic inverse-cosine (acosh) function. The formula for the hyperbolic inverse-cosine operation is as follows − $$\mathrm{cosh^{-1}x\:=\:In(x\:+\:\sqrt{x^2\:-\:1})}, where \:In\: is\: natural\: ... Read More
Hyperbolic functions, which are defined using the hyperbola rather than the circle, are comparable to normal trigonometric functions. It returns the ratio parameter in the hyperbolic sine function from the supplied radian angle. But to do the opposite, or to put it another way. If we want to calculate the angle from the hyperbolic-sine value, we require inverse hyperbolic trigonometric operations like the hyperbolic arcsine operation. This lesson will demonstrate how to use the hyperbolic inverse-sine (asinh) function in C++ to calculate the angle using the hyperbolic sine value, in radians. The hyperbolic inverse-sine operation follows the following formula − ... Read More
