Programming languages translate software designs into instructions for computers, using specialized vocabulary and syntax. Variations range from general languages like C and C++ to scripting languages found in Web development. Programmers work with these languages to write code for applications needed in many industries, from information technology to health care.
With so many different programming languages available, studies usually cover the basic concepts of one or two languages, giving students tools to help them learn other languages as required. Classes may explore the fundamental principles of software design and the common elements of computer programs, such as variables, loops and branches, arrays and structures, and functions and pointers. In programming classes, you would probably learn trouble-shooting procedures for debugging code to make sure that it works correctly.
Programming languages serve as the building blocks for the diverse applications that power modern-day business and communication. Different languages allow coders to build applications ranging from mobile apps for cell phones to services for Internet cloud computing. Professionals familiar with computer languages may work as software developers, often in information services, but also in gaming, education and other fields.
