Variable

Question

Hello,
While coding you have noticed that if you select float or int data type for string data.. Error says, Can't convert to float from 'const char*' And this two words also help you to create a string type variable..
Now the question is, Does, c++ counts strings as an constant array of characters??

Another thing
const char* - - - 8bits
string - - - 32bits
Why??

Answer 1

C++ string can not be seen as a character array because the quality of changeable length of characters. As we all know array is fixed sized.

std::string works like array because you access the character like you do in array, but in reality it's not an array.

About sizeof, An array is a type that allocate a continuous memory to store the elements of the same data type, while std::string is a class and rather complicated.

We do not really know how std::string is implemented, but since it's a class, we can guess that it has other various members and functionality which potentially increase the size of a string.
