I wanted to ask why would some insert a single line comment inside a multi line comment?

Question

Why would a need arise to put a single line comment within multi line comment?
I would be grateful if you please give me and example too.

Answer 1

They might've written a method and added some comments, then later decided to comment the entire method in case they might need to use the method later. This is one way to get a single line comment in a multi line comment.

/*void printCars(){
//print Car 10 times.
for (int i=0; i<10;i++){
std::cout<<"Cars"<<i;
}
}*/
