It is impossible.
Best you can do:

i used cout <<pow(2,1000) and now i want to be able to read its value its very very long number it must be possible to be readed one by one also digits , i didnot save pow (2,1000) to any variable so i just want to do smth like string number = pow (2,1000); and string will have value of this huge number if char array cant do this
