Turbo C is a discontinued integrated development environment (IDE) and compiler for the C programming language from Borland. First introduced in 1987, it was noted for its integrated development environment, small size, fast compile speed, comprehensive manuals and low price.
While arrays in C are fixed, pointers to them are interchangeable. This flexibility allows C to manipulate any length array using the same code. It also leaves the programmer with the responsibility not to write outside the allocated array, as no checks are built in into the language. In Pascal, arrays are a distinct type from pointers.
C99 and C11 added several additional features to C that have not been incorporated into standard C++ as of C++20, such as complex numbers, variable length arrays (complex numbers and variable length arrays are designated as optional extensions in C11), flexible array members, the restrict keyword, array parameter qualifiers, and compound literals.
A basic example is in the argv argument to the main function in C (and C++), which is given in the prototype as char **argv—this is because the variable argv itself is a pointer to an array of strings (an array of arrays), so *argv is a pointer to the 0th string (by convention the name of the program), and **argv is the 0th character of the ...
Turbo Pascal was compactly written and could compile, run, and debug all from memory without accessing disk. Slow floppy disk drives were common for programmers at the time, further magnifying Turbo Pascal's speed advantage. Currently, older versions of Turbo Pascal (up to 5.5) are available for free download from Borland's site.
Flexible array members were officially standardized in C99. [4] In practice, compilers (e.g., GCC , [ 5 ] MSVC [ 6 ] ) provided them well before C99 was standardized. Flexible array members are not officially part of C++ , but language extensions [ 7 ] are widely available.
Of all 8051 compilers, several widely used C compilers exist, but only a few Pascal compilers. Turbo51 is available as freeware and was created with the goal to make a Pascal compiler for MCS-51 processors that will be as fast as Turbo Pascal , will use the same syntax and will generate high quality optimized code.
PascalABC.NET was developed by a group of enthusiasts at the Institute of Mathematics, Mechanics, and Computer Science in Rostov-on-Don, Russia. [1] In 2003, a predecessor of the modern PascalABC.NET, called Pascal ABC, was implemented by associate professor Stanislav Mikhalkovich to be used for teaching schoolchildren instead of Turbo Pascal, which became outdated and incompatible with modern ...
