How to call a JavaScript function from C++?
Calling a JavaScript function directly from C++ depends on the environment and the system; for this, make sure you have embedded a JavaScript engine or integrated C++ with JavaScript. In this article, we will be using Emscripten (C++ to JavaScript in WebAssembly) to call a JavaScript function from C++. For this, you have to compile the C++ program to WebAssembly using Emscripten and then call JavaScript functions from C++. So, first, create the C++ file with the header . How Emscripten Works Emscripten compiles C++ code to WebAssembly, which runs in browsers. The compiled WebAssembly module can ...
Read MoreC program to Implement Kadane’s Algorithm
We are given an array of integers, and we need to find the maximum sum of a contiguous subarray using Kadane's Algorithm. Kadane's Algorithm is an efficient way to find the maximum subarray sum in O(n) time complexity. For example, in the array {-2, 1, -3, 4, -1, 2, 1, -5, 4}, the subarray [4, -1, 2, 1] has the maximum sum 6. What Is Kadane's Algorithm? Kadane's algorithm is a popular and optimal algorithm used to find the maximum sum of a contiguous subarray in a given array of integers. This algorithm efficiently solves the Maximum Subarray ...
Read MoreDifference between C and C++
Both C and C++ are middle-level programming languages that are used for developing system software as well as application software. C is a procedural programming language which have low-level memory access and minimal runtime; therefore, it is used for writing operating systems, embedded systems, and system-level programs. whereas C++ is just an extension of the C language, which is both a procedural programming language and object-oriented. Therefore, having extra features that make it suitable for game development, GUI applications, and high-performance software. C Programming Language C is a general-purpose, procedural programming language, which was developed by Dennis ...
Read MoreA C Puzzle in C Programming?
C programming puzzles are small but tricky coding problems designed to challenge and enhance understanding of the C programming language through creative solutions. Problem Statement We are given two numbers, and our task is to combine them in such a way that the second integer is placed before the first integer, resulting in a single combined integer. However, we are not allowed to use any logical, arithmetic, string-related operations, or any pre-defined functions. Consider the following input/output scenarios to understand the puzzle statement better − Scenario 1 Input: 12, 54 Output: 5412 ...
Read MoreAddress of a function in C or C++
In C programming, every function is stored in the computer's memory and has a unique memory address, just like variables. We can access and display these function addresses to understand how functions are stored in memory. Syntax functionName // Returns address of the function (void*)functionName // Cast to void pointer for printing Accessing Address of a Function To access the address of a function, we use its name without parentheses. When we write hello() with parentheses, we're calling the function. But when we write just hello, it ...
Read MoreType difference of character literals in C and C++
Character literals are values assigned to character data type variables. They are written as single characters enclosed in single quotes (' ') like 'A', 'b' or '2'. However, the type of character literals differs between C and C++. In C, character literals are stored as type int, whereas in C++ they are stored as type char. This fundamental difference affects memory usage and type safety. Syntax 'character' // Character literal syntax Type of Character Literal in C In C, character literals have type int and occupy 4 bytes of memory. This happens ...
Read MoreWhen to use C over C++, and C++ over C?
Both C and C++ are powerful programming languages used by developers to write system-level and application programs. C follows a procedural programming paradigm with a simple and structured approach, while C++ supports both procedural and object-oriented programming. Although both languages are widely used across various fields, they have different strengths and use cases. This article explores when to choose C over C++ and vice versa. When to Use C Language? C is preferred in the following scenarios − System Programming: When writing low-level system software like operating systems, embedded systems, or ...
Read MoreAlignof operator in C++
C++ alignof() Operator The alignof operator is the operator that returns the memory alignment for a given variable type. This alignment tells how the data is arranged and accessed in memory. It returns the value in bytes and is the part of the header file in C++. which is mainly used for low-level programming like memory management or hardware requirements. Syntax Here is the following syntax of alignof operator, which returns memory alignment required for a given data type in bytes: alignof(data_type) Example Demonstrating Usage of alignof() Operator Here is the following example code of using alignof() operator ...
Read MoreCheck if a line passes through the origin in C++
In this article, we have a line and its coordinates are given. Our task is to check if this line passes through the origin or not. The basic two-point form of a straight line is given by: $$ \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1} + c $$ For the above line to pass through the origin, put x = 0, y = 0, and c = 0. The formula for a straight line to pass through the origin can be given by: $$ y_1(x_2 - x_1) = x_1(y_2 - y_1) $$ Here are some ...
Read MoreCheck if a large number is divisible by 11 or not in C++
In this article, we are given a larger number and we need to check whether it is divisible by 11 or not using the C++ program. To handle large numbers, we treat the number as a string and apply a divisibility rule to check if it's divisible by 11. Rule of Divisibility by 11 A number is divisible by 11 if the difference between the sum of its digits at odd positions and the sum of its digits at even positions is divisible by 11. Consider the following example scenarios to understand the divisibility of a large number ...
