What is the size of a string in C++? - sizeof(string)

When it comes to determining the size of a string in C++, it's important to note that the sizeof operator will not necessarily return the actual size of the string. Instead, it will return the size of the string object itself, which includes any overhead that may be associated with the object.

In C++, the string class is typically implemented as a dynamic array of characters, with additional variables to keep track of the size of the array and the length of the string. This means that the size of a string can vary depending on its contents and the implementation of the string class.

To get the actual size of a string in C++, you can use the length() or size() member functions of the string class. These functions will return the number of characters in the string, which can be used to calculate the actual size in bytes (assuming each character is one byte).

In summary, the sizeof operator in C++ will only give you the size of the string object, not the actual size of the string itself. To determine the actual size of a string, you should use the length() or size() member functions of the string class.
