[edit] Usage

goto statement: as the declaration of the statement

[edit] Example

Run this code

#include <cassert>
#include <string>
 
[[nodiscard]] auto get_first_line(const std::string & string)
{
 std::string first_line{};
 for (const auto 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");
}
