Swift Program to Add Two Complex Numbers by Passing Class to a Function
In swift, a complex number is the combination of real and imaginary number. So we create a class to store the real and imaginary part of the complex number and then we pass this class in the function to find the sum of two complex numbers. Algorithm Step 1 − Create a class to store the real and imaginary part of the complex number. Step 2 − Create a function named as ‘add’ which takes two class objects as a parameters and return the sum of the two complex numbers by adding the real and imaginary part ...
Read MoreGolang program to convert the local time to GMT
In this article, we will learn to write a Go language program to convert the local time to GMT using internal functions like Now() Time, LoadLocation()and time.In(). Local time is the time of a particular region which is calculated using position of the sun at noon. The local time is obtained using Now function from the time package whereas the local time is converted to GMT using ln function from the time package. Syntax func Now() Time The Now() function is defined in time package. This function generates the current local time.To use this function, we have to first ...
Read MoreC++ Program to Get Input from the User
While writing a program in any language, taking input is a fundamental job that we do in almost all programs. Sometimes we take input directly from the console or take the inputs from the files. Taking inputs from the files is somewhat beneficial because it does not require us to type inputs again and again, or sometimes we can save some good input test cases into a file. However, in this article, we are going to focus on console-based inputs. We will learn different techniques to get inputs from the user in C++. There are a few different approaches to ...
Read MoreC++ Program to calculate the Highest Common Factor
The highest Common Factor or Greatest Common Divisor are factors that are maximum and that can divide two or more values without generating any remainder. In this article, we shall discuss a few methods to perform HCF / GCD between two numbers in C++. This is simply a mathematical solution and there are several algorithms present to find GCD. The Euclidean method to find GCD is common. The same algorithm we will use in iterative mode, and recursive mode. Using Iterative method The iterative solution for the Euclidean gcd finding algorithm is shown in the algorithm section. Algorithm ...
Read MoreGolang Program to Check Whether an Alphabet is Vowel or Consonant
In this tutorial we will write a go language code to check whether an alphabet is vowel or consonant. Difference between Vowel and Consonant A character is called vowel if it is in any one of the following list of characters {a, e, I, o, u}. All the remaining characters are called consonants. In English language there are 5 vowels and 21 consonants. Here we are going to use following 2 methods − Method 1: Using if/else statement In this method we will use the conditional statements to check if a character is a vowel or consonant. Method 2: Using ...
Read MoreHow to escape any special character in Python regular expression?
Regex, often known as regexp, is a potent tool for finding and manipulating text strings, especially when processing text files. Regex may easily replace many hundred lines of computer code with only one line. All scripting languages, including Perl, Python, PHP, JavaScript, general-purpose programming languages like Java, and even word processors like Word, support Regex for text searching. Regex may be challenging to learn because of its complicated syntax, but it is time well spent. Special Characters Text processing becomes more challenging when special characters are included because context must be carefully considered. You must think about what you see, ...
Read MoreHow does del operator work on list in Python?
Lists are one of the four most commonly used data structures provided by Python. A list is a data structure in python that is mutable and has an ordered sequence of elements. Following is a list of integer values. lis= [1, 2, 3, 4, 5] print(lis) If you execute the above snippet, it produces the following output. [1, 2, 3, 4, 5] In this article, we will learn how a del operator works on a list in python. They are various scenarios where we use the del operator. The del operator The del keyword is mostly used in ...
Read MoreHow to Get a List of Current Open Processes Java?
It is essential for the user to know about the processes that are running in their system, be it foreground or background. To do so in windows we have a task manager but internally it uses a program called tasklist. Tasklist aside from giving us the currently running processes, it also gives us details like process id, session name, session and memory usage of each process. In this article we will see how we can get a list of currently open processes by using Java programming language. Algorithm Step 1 − Create a process that executes the tasklist.exe Step 2 ...
Read MoreGolang program to implement returning pointer from a function
In this article, we will write Golang programs to implement returning pointer from a function. A pointer stores the address of another variable and the address is depicted using & operator. Algorithm Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and Output. Step 2 − Create a function create_pointer that returns a pointer to the int Step 3 − Set the value of x in the function and return the variable back to the function Step 4 − Create a main ...
Read MoreGolang program to parse time
In golang we can use various internal time function to parse time. Time is parsed using parse and ParseInLocation method. Syntax time.Parse() This function belongs to time package. It is used to parse the string into time.Time value and it takes two inputs: the layout and the time string which is to be parsed. time.ParselnLocation() This function is a part of the time package. It is used to parse the string into time.Time value along with a specified location. It takes 3 arguments: the location, layout string and the time string. time.Format() This function is present in ...
