Subprogram
Advantages
of Subprograms:
o You can write and test
one module separately from the rest of the program.
o Debugging is
easier because you work with smaller sections of the program.
o Modules can be
used in other programs without rewriting or retesting.
o Programs are more readable.
o More than one
programmer can work independently on a program
o Programs are shorter, therefore less subject
to error.
o A module can be used several times by the
same program.
Subprogram is an independent module
containing series of computer
instructions that together that form the key to top down software design.
