c++ - Difference between null terminated char (\0) and `^@` -

c++ - Difference between null terminated char (\0) and `^@` -

my codes this:

#include <iostream> using std::cout; using std::endl; int main(int argc, char *argv[]) { cout << (int)('\0') << endl; cout << (char)(0) << endl; homecoming 0; }

i expected see in terminal this:

$ test-program 0 $

however, saw this:

$ test-program 0 ^@ $

what makes me confusing think '\0' can converted 0. , 0 can casted \0. expected see null char followed endl, result weird ^@.

does have ideas this?

^@ how terminal emulator renders '\0'.

c++ c arrays string char
