part 2 in previous lesson we seen about approach of c++ language first list(procedural ) second modules: large project our data separate each other function and data separated gen.pin() pin difficult to conceptualize. difficult to modify 3 oop(object oriented programmer) bind function and data together create class(blueprint or object) encapsulation class (does not take space in RAM only blue print not actual House) member variable and member function class(keyword) house (class name){ we will create block( write " int length, breadth // member function void setdata(int x, int y) {length=x ; breadth = y; } void area () { cout << length* breadth; } and data memebere ) }......

programming 2 chapter 1 Introduction ''we have three approach 1, procedural progreamming list of instraction in a single block ex #include <iostream> using namespace std; void main ()/ int main() { list some part of your problem; returb 0; } this approach isn't figure out big task but only to solve small case it suitable for solve some part 2, modular programming in this procedure we divide into functional eg void main () { function1 () function2 () } also this not comfortable with relat real world it difficult to variable(local) . data remain alive within module two type variable global and local local : use in specific place global : use anywhere (through out program) modern application create global variable eg ETM application have some function withdrawal() check_balance() gen.pin() mini stmt() also having some global variable pin(before withdrawal using your pin) balance(after withdrawal how much money you want) name 3.... cont
