A string is a sequence of characters, including alphabets, numbers, and symbols. In this tutorial, we are going to learn how we can count the number of vowels in a given string in PHP using different approaches. Vowels in English are a, e, i, o, u, and they can be either uppercase or lowercase. What is a Vowel? Vowels are alphabetic characters that represent specific speech sounds.There are a total of five vowels, both uppercase and lowercase in the English language: a, e, i, o, u Example 1 Input: string = "Tutoriaspoint" ...

A square is a closed two-dimensional figure having 4 equal sides. Each angle of a square is 90 degrees. The perimeter of a square is the sum of all its sides. Problem Description In this problem, we are given the side of a square, and we have to find the perimeter of the square. In this tutorial, we are going to find the perimeter of a given square in Python using different approaches. Example 1 Input: side = 6 units Output: 24 units Explanation Using the formula to calculate ... Read More
Both compilers and assemblers are the language processors used to convert software codes written in high-level language and assembly language into machine language codes. Compiler and assemblers are the types of system software. These are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. and assembly language. Therefore, it is necessary to convert an HLL or assembly code into machine code for execution. In this article, we will highlight all the key differences between compilers and assemblers. Let's start with some basics of compiler and assembler so that it will ... Read More
Let's begin this article with a basic question. What do you mean by Language Translator? You may imagine a tool or piece of software that can translate between languages as needed so that both parties can understand. You are totally correct. Compilers and interpreters are simply language translators in computer programming. These are the software programs/tools that translate the source code of a programming language into machine code, bytecode, or any other intermediate code. Or, to put it simply, it transforms code from High Level Language to Low Level Language, making it machine understandable code. Every programmer is aware that interpreter ... Read More
One-Pass CompilerOne pass compiler reads the code only once and then translates it. The one-pass compiler passes only once through the parts of each compilation unit. It can translate each part into its final machine program. In the one-pass compiler, when the line source is processed, it is scanned and the token is extracted. This is in contrast to a multi-pass compiler which modifies the program into one or more intermediate representations in steps between source program and machine program, and which convert the whole compilation unit in each sequential pass.A one-pass compiler is fast since all the compiler code ...

Java Virtual Machine is an abstract computing machine which is used to run the java program. JVM accepts byte code, loads it and translates it into system understandable code.Check here the Tutorials Point Java compiler
Both compilers and interpreters are the language processors used to convert software codes written in high-level language into machine language codes. Compilers and interpreters are types of system software. They are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. Therefore, we convert a HLL code into machine code for execution. In this article, we will highlight all the major differences between a compiler and an interpreter. Let's start with some basics so that it will become easier to understand their differences.

To check if a string can be obtained by rotating another string by 2 places, we have used Javascript substr() method. We will be understanding the code with an example and step wise explanation of the code. In this article we are having two strings: str1 and str2, where str1 is the given string and str2 is the rotated string. Our task is to check if the string (str2) can be obtained by rotating another string (str1) by 2 places. Example Input: str1 = TutorialsPoint str2 = torialsPointTu Output: true (with 2 left rotations) Input: ... Read More
The methods used in cyber crimes are constantly evolving in the digital age we live in, and it is therefore crucial to understand the specifics of each type of attack in order to protect company data. Password attacks and credential stuffing are two major instances of digital risk exposure. We examine the details in this article, which includes learning about the differences between them. What is a Password Attack? A resentful attempt to figure out or crack a password in order to get permission to access accounts and systems without authorization is known as a password attack. Attackers use a variety ... Read More
