Why OOP is said to be a better choice for software development ?

Well say OOP to be a master of all evils and evil is successful today...

how did you get your hair to be green?

oop "object orinted programming" is better because it models the real life in a similar way
every thing in life is divided in to object form a spicific thing "class"
u r an object from the class human
cats r objects from class pets that is diverted from class animals
if u divid ur problem u r try to solve in the program u write in to objects u will find it much easer
and this will aslo make it possible to address harder problems in an organized way
i hope u find what i have said have any meaning, coz understanding how to divid and approch the problem is much importent than how u solve it

You are right Brigadi

Because most real world problems are more easily understood as entities and relationships between those entities. The most often other used approach is procedural, which, if a problem is truely procedural, works great. OO is better for maintaing state, but as a result, uses more memory.
Plus what Brigadi said.
