Differences in computer languages is a topic that many people are not familiar with. I was one of those kinds of people before I started researching on this topic. There many different computer languages and each one of them are similar in some ways, but are also different in other ways, such as: program syntax, the format of the language, and the limitations of the language.

Most computer programmers start programming in languages such as turbo pascal or one of the various types of basic. Turbo pascal, Basic, and Fortran are some of the oldest computer languages. Many of today's modern languages have been a result of one of these three languages, but are greatly improved. Both turbo pascal and basic are languages that are easy to understand and the syntax is very easy and straightforward. In Basic when printing to the screen you simply type the word 'print', in turbo pascal you would type 'writeln'. These are very simple commands that the computer executes. To execute a line of code in a language such as C, or C++, you would have to type in much more sophisticated lines of code that are much more confusing than the previous two.

The format and layout of the various languages are very diverse between some, and between others are somewhat similar. When programming in Basic the user has to type in line numbers before each new line of code. In an updated version of Basic called QBasic, numbers are optional. Turbo pascal does not allow the user to input numbers, it has preset commands that separate each part

of the program. This is similar to QBasic, but is much more sophisticated. Instead of using the command gosub in Basic, the user would make a procedure call.

Another new language is C. C is a spinoff of turbo pascal but is capable of doing more things than turbo. The format and layout are similar, but the syntax is much more complex than turbo is. When C first came out, there were many major...
