Usage

• goto statement: as the declaration of the statement

Example

Run this code

#include <cassert>#include <string>   [[nodiscard]]auto get_first_line(conststd::string& string){std::string first_line{};for(constauto character : string)switch(character){case'\n':goto past_for;// breaks from 'range-for loop'default: first_line += character;break;} past_for:return first_line;}   int main(){assert(get_first_line("Hello\nworld!")=="Hello");}
