In computer programming, a block or code block or block of code is a lexical structure of source code which is grouped together. Blocks consist of one or more declarations and statements . A programming language that permits the creation of blocks, including blocks nested within other blocks, is called a block-structured programming language .
The higher the branching factor, the faster this "explosion" occurs. The branching factor can be cut down by a pruning algorithm. The average branching factor can be quickly calculated as the number of non-root nodes (the size of the tree, minus one; or the number of edges) divided by the number of non-leaf nodes (the number of nodes with ...
An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
Richard C. Johnson et al. (1994) proposed a program structure tree (PST), a hierarchical representation of program structure based on single edge entry and single edge exit regions. [5] [6] The PST can be computed in (| |) time for an arbitrary flow graph, where is the set of edges in the graph. The disadvantage of the PST is that it exploits ...
Constructing an overlay program involves manually dividing a program into self-contained object code blocks called overlays or links, generally laid out in a tree structure. [ b ] Sibling segments, those at the same depth level, share the same memory, called overlay region [ c ] or destination region .
