What is the real difference between the procedural and object-oriented programs?

1. In procedural program, programming logic follows definite procedures and the instructions are executed one after another. In OOP program, unit of program is object, which is nothing but grouping of data and code.

2. In procedural program, data is exposed to the complete program whereas in OOPs program, it is easy to get to with in the object and which in turn assures the safety of the code.
