Comparison of Object Pascal and C
The computer programming languages C and Object Pascal have similar times of origin, influences, and purposes. Both were used to design (and compile) their own compilers early in their lifetimes.
Both C and Pascal are old programming languages: The original Pascal definition appeared in 1969 and a first compiler in 1970. The first version of C appeared in 1972. While C didn't change much in time, Pascal has evolved a lot and nowadays the vast majority of Pascal programming is done in modern Object Pascal, not in the old procedural Pascal. The old procedural Pascal today is essentially limited to microcontroller programming with tools such as mikroPascal, while Object Pascal is the main dialect and is used with tools such as Delphi, Lazarus (IDE) and Free Pascal.
What is documented here is the modern Object Pascal used in Free Pascal and Delphi. The C documented is C99, as standardized in 1999.
== Syntax ==
Syntactically, Object Pascal is much more Algol-like than C. English keywords are retained where C uses punctuation symbols — Pascal has and, or, and mod where C uses &&, ||, and % for example. However, C is actually more Algol-like than Pascal regarding (simple) declarations, retaining the ''type-name'' ''variable-name'' syntax. For example, C can accept declarations at the start of any block, not just the outer block of a function.
