How to run code again without return 0?

Question

What do I do if I want a code to start from the beginning again without return 0 (without a loop)?

Is it just a simple command?

Answer 1

Just make a recursive function with the code you want to return to the beginning to. Main cannot be recursive hence the creation of a different function.

Example:

void sayhi()
{
cout << "hi";
sayhi()
}

int main()
{
sayhi();
}
