How will me do function "sleep" in c++?

Answer 1

Declaring a function in C++ follow this format.

If your function is returning a value.

return_type func_name (parameters){
//What your function does

return; //what to return
}

If it's not returning a value

void func_name (parameters){
//Some code
}

As in sleep function.

void sleep (int hours){
Cout <<"Sleep for" <<hours<<"hours"<<endl;
}
