Why we use constructor in oops ?

in c++ i can access the member function by creating simple object then why we need to create constructor.

actually constructors are so usefull sometime we need to create some object which require some input without it the operation will not successfully execute. ex: suppose we are working with graphics then we need a class of Point but with no constructor it is useless,thus must provide a constructor with (int x,int y) values so whenever someone makes an object of this class it will ask for the x & y values.
