The strength of modular programming lies in the modular approach. Each module holds logically grouped code (functions, procedures, variables, constant data), typically grouped by functionality.
For instance, one module might provide tools to retrieve application-specific data from and store such data in a database, another module might provide visualization primitives, a third might provide an application-specific data structure and related management functions, etc.
As each module is developed, it is tested as a single unit. The idea is to perfect this module, and never to touch it again while the remaining modules are being developed and tested in a similar manner, then put together ("integrated") to form the application.
While the goal of never touching a module, once initially tested, is rarely met in real life terms, modular programming provides a structured approach to application design and helps in producing quality software. A modular design also helps when working in a team, as the modules' boundaries often are natural dividing lines along which the work can be divided between different members of the team.

Modular programming is a design technique which separates a program into small, self-contained units or modules, each focusing upon a particular aspect of the program. Modular programming typically combines structured programming, object oriented programming and generic programming techniques.
Procedural programming is a computer programming technique in which the program is divided into modules like function or subroutine or procedure or subprograms, where as ... "Modular Programming" is the act of designing and writing programs as interactions among functions that each perform a single well-defined function, and which have minimal side-effect interaction between them. Put differently, the content of each function is cohesive, and there is low coupling between functions as happens in procedural programming.
There is no difference between procedural programing language & structure programing language
Modular programming:It is the act of designing and writing programs as interactions among functions that each perform a single well defined function,& which have minimal side effect interaction between them.It is heavily procedural.The focus is entirely on writing code(functions). Data is passive.Any code may access the contents of any data structured passed to it. Object Oriented programming:it is a programming paradigm using "objects"-data structures consisting of data fields & methods together with their interactions-to design applications and computer programs.programming techniques may include features such as data abstraction,encapsulation,messaging,modularity,polymorphism and inheritance.
The use of Object Oriented Programming is used primarily to: * Make programs easier to read * Modify programs faster * Create modular programs
