Question:
Does C++ have a goto statement? If yes, how does it work (what is the syntax)? If no, is there an equivilant and what is the syntax?
Answer:
Yes, both C and C++ have the goto keyword. The syntax is simple: you need to put a label after the keyword goto to perform a jump. A label is a user-defined name followed by a colon, which indicates a code section. For example:
int main(){ int x=0; my_label: // a label if (x < 3) { ++x; goto my_label; }}
As you probably know, goto is almost never needed in structured programming languages such as C and C++. For-loops, while-statements and function calls are used instead. However, goto can be useful in machine-generated code and in real-time applications. This is why it still exists in both languages.
