I have been wrong too; it is all about how you handle it.

People don’t lose respect for you for being wrong.  They lose respect for you for handling it poorly.

sizeof returns the length in bytes of a char. - whether it be a array or what not. Whatever - I was trying to help out; screw that idea.

You are, unfortunately, blatantly wrong on this count.

sizeof() returns the correct size for the given type, or the correct length of a statically allocated array. std::string uses dynamically allocated memory to store the string contents, so sizeof() will not see that memory.

#include <string>
#include <cassert>
int main() {
	std::string A = "Hello, World!";
	std::string B = "Hi";

	assert( sizeof(A) == sizeof(B) );
}

there is size_t; and plus sizeof() returns bytes of characters. Rather it be a sturct, a class or whatever.

“string” is a structure, so sizeof() returns the size of that structure, not the size of the string it manages.
If it was instead:

const char szString[] = "Hello fellow citizens.";

Then sizeof() would return the number of characters, including the terminating NULL.

screw that idea.

I supported you on SIZE_T but I feel less sorry for you after you posted this.


L. Spiro

SIZE_T just returns a integar or length of bytes for the string. SIZE_T is the same function of sizeof(). SIZE_T just stores the integar length of a string or what not.

SIZE_T StringLength;
string Greeting = "Hello, I'm George!";
StringLength = sizeof(Greeting);
cout << StringLength;

As you see the SIZE_T is a typdef that stores the integer of length. Where as sizeof function returns the length of the string Greeting.

std::string varString = "Hello World";
unsigned int size = sizeof(varString);
sizeof DOES NOT RETURN THE SIZE OF THE STRING INSIDE THE STD::STRING

It returns the size of the string class.  The string class uses dynamic memory to store cstrings.  So only the pointer is counted as well as any other members.  If you want the size of an std::string you use .size();

SIZE_T StringLength;
string Greeting = "Hello, I'm George!";
StringLength = sizeof(Greeting);
cout << StringLength;

float PI = 3.14;
float ConvertFloat = (double)PI;

-- or --

double AnotherPie = PI;
