In the early 1980s, Borland enjoyed considerable success with their Turbo Pascal product and it became a popular choice when developing applications for the PC. Borland followed up that success by releasing Turbo Prolog (in 1986), and in 1987, Turbo Basic and Turbo C. Turbo C has similar properties to Turbo Pascal: an integrated development environment, a fast compiler (though not near the ...
Here are two benchmark examples: A recursive Fibonacci algorithm on a 1.8 GHz Intel Centrino laptop with 512 MB RAM yields a noticeable difference in results between Microsoft Visual C++ compiler 13.10.3052 and TCC. To calculate the 49th Fibonacci number, it took a MS Visual C++ program approximately 18% longer than the TCC compiled program.
c = a + b In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also ...

Other languages, such as BASIC, C/C++, Python, and Perl, are also used on commercial and military programs for testing of systems; ATLAS typically requires another computer system to either optically scan test results, or read a tape, disk, or locked memory stick/data key from a test station and then perform statistical analysis on test results ...
Hence, it is not possible to define an array whose length depends in any way on program data. (Note : since 1986 and Turbo Pascal 3, which was the industry standard, GetMem() allows dynamic arrays in everyday Pascal, if not in the ISO standard) C has the ability to initialize arrays of arbitrary length.
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 ...
Below is a sample procedure for sorting an array, although SortArray is now a built-in function of PureBasic. Procedure bubbleSort ( Array a ( 1 )) Protected i , itemCount , hasChanged itemCount = ArraySize ( a ()) Repeat hasChanged = # False itemCount - 1 For i = 0 To itemCount If a ( i ) > a ( i + 1 ) Swap a ( i ), a ( i + 1 ) hasChanged ...
