Structured Programming Approach

Structured Programming Approach: The basic principal of structured programming approach is to divide a program in functions and modules. The use of modules and functions makes the program more comprehensible (understandable). It helps to write cleaner code and helps to maintain control over each function. This approach gives importance to functions rather than data. It focuses on the development of large software applications. The programming languages: PASCAL and C follow this approach. 

Procedural Programming Approach

Procedural Programming Approach: This approach is top down approach. In this approach, a program is divided into functions that perform a specific task. Data is global and all the functions can access the global data. Program flow control is achieved through function calls and goto statements. This approach avoids repetition of code which is the main drawback of Monolithic Approach. The basic drawback of Procedural Programming Approach is that data is not secured because data is global and can be accessed by any function. This approach is mainly used for medium sized applications. The programming languages: FORTRAN and COBOL follow this approach.
