By contrast, languages in the FORTRAN/ALGOL tradition, notably languages in the C and Pascal families, used the hyphen for the subtraction infix operator, and did not wish to require spaces around it (as free-form languages), preventing its use in identifiers.
Both are descendants of the ALGOL language series. ALGOL introduced programming language support for structured programming, where programs are constructed of single entry and single exit constructs such as if, while, for and case. Pascal stems directly from ALGOL W, while it shared some new ideas with ALGOL 68.
Delphi – Object Pascal is essentially its underlying language. Free Pascal compiler (FPC) – Free Pascal adopted the standard dialect of Borland Pascal programmers, Borland Turbo Pascal and, later, Delphi. PascalABC.NET – a new generation Pascal programming language including compiler and IDE.
Some languages define a special character as a terminator while some, called line-oriented, rely on the newline. Typically, a line-oriented language includes a line continuation feature whereas other languages have no need for line continuation since newline is treated like other whitespace. Some line-oriented languages provide a separator for ...
Modern programming languages use symbols to represent concepts and/or data and are, therefore, examples of symbolic languages. [1] Some programming languages (such as Lisp and Mathematica) make it easy to represent higher-level abstractions as expressions in the language, enabling symbolic programming. [2] [3]
The original Hungarian notation for programming, for example, specifies that a lowercase abbreviation for the "usage type" (not data type) should prefix all variable names, with the remainder of the name in upper camel case; as such it is a form of lower camel case. Programming identifiers often need to contain acronyms and initialisms that are ...
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
^c In languages of the Pascal family, the semicolon is not part of the statement. It is a separator between statements, not a terminator. It is a separator between statements, not a terminator. ^d END-IF may be used instead of the period at the end.
