A macro is a textual substitution taken care by the preprocessor so, yes you can. You can define a macro for a goto statement and/or a label.
Ps. anyway that's a terrible practice.. both using lots of macros and using gotos
#include <iostream>#define GOTOSTMT goto helloworld;#define LABELSTMT helloworld:int main() { int i = 0; LABELSTMT std::cout << "Don't ever program like this" << std::endl; i++; if(i < 3) GOTOSTMT}
