An array is a fixed-size collection of elements of the same data type that stores data in contiguous memory locations. Initializing an array with one default value in C++ is an easy task and can be easily implemented using various approaches that we are going to understand with code examples. Initializing Array with Zeroes in C++ To initialize all elements of an array with 0, we will simply initialize the array with 0 or just use empty curly braces. Example Here is an example that uses the above mentioned methods to initialize the array with 0: #include using ... Read More
While executing the statements that perform arithmetic operations, if any operation results in an illegal value, an arithmetic exception occurs (run time).In Python, ArithmeticError represents this exception, and it is the base class for all errors that occur during arithmetic operations, such as division by zero, overflow, or floating-point errors. Catching this exception helps to manage errors that arise from calculations. Catching ArithmeticError with try-except Block You can use a try-except block in Python to catch ArithmeticError and handle errors related to arithmetic operations like division by zero or overflow. This allows your program to continue running smoothly even if ... Read More
The tag is used to drawn horizontal line on a web page. This tag is one of useful HTML tag. It is used to separate the content by drawing a horizontal line between different sections. In this guide, we are going to learn how we can change the thickness of an tag using CSS using different methods. The tag in HTML The tag stands for horizontal rule. It is a self-closing tag that is used to visually divide the sections of a web page using a horizontal line. Example Section 1 ... Read More
SyntaxError in Python occurs when the interpreter encounters invalid syntax, such as missing colons, unmatched parentheses, incorrect indentation, or invalid keywords. Since this error happens during the code compilation stage (before execution), it cannot be caught using a regular try-except block. To handle it, you must wrap the faulty code inside the exec() or compile() functions within a try-except block. Here, we are demonstarting the occurence of SyntaxError and handling it using the following methods - exec() Method compile() Method Using a custom function with exception handling ... Read More
A ternary tree is a type of tree data structure in which each node can have at most three children. In this article, we will learn how to implement a ternary tree in C++ using basic class structures and pointers. What is Ternary Tree? A ternary tree is a tree in which each node has up to three children, that is left, middle, and right. It is same as a binary tree, but with an extra child node for each node. Each node in a ternary tree stores a data value and pointers to its three child nodes. ... Read More
In this article, you will learn the setup to build and compile the C++ code in Visual Studio. Here you will become familiar with many of the tools and dialog boxes that you can use when you develop applications in C++. In this, we'll create a "Hello, World" style console application to help you learn more about working in this IDE. Prerequisites For this, you need a copy of Visual Studio 2017 version 15.3 or later, with the Desktop development with C++ workload installed. You can follow this guide to see the full installation procedure of Visual Studio [Link]. Create ... Read More
In this article, we will show you how to find the length of a string in C++. A string in C++ is a sequence of characters, such as letters, numbers, symbols, or anything enclosed in double quotes (e.g., "Hello"). To find the length of a string, we count all the characters, including spaces, but we don't count the null terminator('\0'). For example, let's look at the following string in C++. // Example 1 Input: "Learning C++ with tutorialspoint is fun!" To find the length, we count every character, including spaces. So, the total length is 40. Output: 40 ... Read More
In this article, we'll show how to write a C++ program to concatenate two strings. A string in C++ is a sequence of characters like letters, numbers, symbols, or anything enclosed in double quotes (e.g., "Hello"). Concatenating two strings means joining them together to form one combined string. For example, if we have two strings: str1 = "Welcome to" and str2 = "tutorialspoint!", after concatenation, the result will be: result = "Welcome to tutorialspoint!". Approaches to Concatenate Strings in C++ We can concatenate strings in C++ using different methods. Below are the approaches we will cover: ... Read More
Any linear equation in one variable has the form aX + b = cX + d. Here the value of X is to be found, when the values of a, b, c, d are given. Let's understand this with an example: //Example 1 If the input equation is 2X + 4 = -9X + 14, the solution is: => 2X + 9x = 14 - 4 => 11X = 10 => X = 10 / 11 = 1.1 //Example 2 If the input equation is -3X + 5 = 4X - 9 the solution is: => -3X + ...

In this article we are going to discuss the set::find() function in C++ STL, their syntax, working and their return values. What is Set in C++ STL? Sets in C++ STL are the containers which must have unique elements in a general order. Sets must have unique elements because the value of the element identifies the element. Once added a value in a set container later can't be modified, although we can still remove or add the values to the set. Sets are used as binary search trees. What is set::find() The std::find() function is an inbuilt function in C++ ... Read More
