Considering I have the following program that determines the size of multibyte characters.
#include<iostream>
int main()
{
std::cout<<"size of multibyte characters : "<<sizeof('ab')<<std::endl;
}
My GCC compiler gives an output of 4.
So I have the following questions:
sizeof('ab')
equal to sizeof(int)
? This is a so-called multicharacter literal, which unlike its single character counterpart, is not of type char
, but of type int
(assuming its supported). As specified in [lex.ccon]/2 , emphasis mine:
A character literal that does not begin with u8, u, U, or L is an ordinary character literal. An ordinary character literal that contains a single c-char representable in the execution character set has type char , with value equal to the numerical value of the encoding of the c-char in the execution character set. An ordinary character literal that contains more than one c-char is a multicharacter literal. A multicharacter literal , or an ordinary character literal containing a single c-char not representable in the execution character set, is conditionally-supported, has type int , and has an implementation-defined value.
So you print sizeof(int)
, as you suspected.
