This technique is similar to divide-and-con-

quer technique. Dividing a large program into

smaller functions pr

ovides advantages to the

programmer. The testing and debugging of

a program with functions becomes easier. A

function can be called repeatedly based on the

application and thus the size of the pro gram

can be reduced. The message passing between a

caller (calling function) and callee (called func-

tion) takes places using arguments. The con-

cept of modular approach of C++ is obtained

from function. Following are the advantages of

functions:

a. Support for modular programming

b. Reduction ...
