Computer science is the study of computing, programming, and computation in association with computer systems. This study involves theories that define how a computer works to design, test, and analyze concepts.
In computer science, a string is a fundamental data type used to represent text, as opposed to numeric data types like integers or floating-point numbers. It contains a sequence or "string" of characters, which may include letters, numbers, symbols, and spaces. In most programming languages,...

String is a collection of characters. It is a one dimensional array of characters. There are two ways to declare string in c language. 1. By char array 2. By string literal Declaring string by char array char c[11]={'i', 'n', 't', 'e', 'l', 'l', 'i', 'p', 'a', '...
Computer science is a philosophy and a field of study that covers basically all aspects of information access, particularly as relates to computer code, technical engineering, and Internet communications. Some of the people who work in this area have jobs as programmers, using algorithms to study ...
Classes in computer science are not just about learning programming languages, although that is a significant part of the curriculum. As a CS major, expect to take discrete math and other math-related classes. You will also take engineering, theory, systems, and networks classes. ...
2. What Is a Semaphore? A semaphore is an integer variable, shared among multiple processes. The main aim of using a semaphore is process synchronization and access control for a common resource in a concurrent environment. The initial value of a semaphore depends on the problem at hand. Usua...
What Hammond is referring to is the question of meaning, and meaning is central to what distinguishes the least intelligent of humans from the most intelligent of machines. A computer works with symbols. Its program specifies a set of rules to transform one string of symbols into another. But ...
Computer science is a major for problem-solving students who want to learn how to use computers and computational processes to build websites, program robots, mine data and more. Computer science majors may go on to master’s or doctorate programs in the field, and they can work in research...
