Selection and Bubble Sort Algorithm

Pseudocode - Selection Sort and Bubble Sort

Java demonstrations of sorting algorithms from www.sorting-algorithms.com

Selection Sort Code in several programming languages

Selection Sort in multiple languages

Most current languages are based on the C Programming Language

Most langauges clearly show the two nested loops with the if statement inside

Most languages are structured, written with indented nesting of loops and if statements

Another good source of examples: http://rosettacode.org/wiki/Sorting_algorithms/Selection_sort

Bubble Sort Code in several programming languages

Bubble Sort in multiple languages

Another good source of examples: http://rosettacode.org/wiki/Sorting_algorithms/Bubble_sort

The most radically different languages are Assembly, FORTRAN, COBOL, and Lisp, all old languages pre-dating C
