Structured
programming is a technique for organising and coding computer programs in which
a hierarchy of modules is used, each having a single entry and a single exit
point. Code is written in such a way control is passed downward through the
structure without unconditional branches to higher levels of the structure. Three
types of control flow used are:
1. Sequential
2. Test
3. Iteration
Structured
programming employs top-down design model in which the developers map out the
overall program structure into separate subsections. In structured programming
codes can be loaded into memory in efficient manner and codes can be reused
easily.
