What is the difference between #include<iostream> and using namespace std??
iostream is a library that have function like (cin cout int float...) Using namespace std is a shortcut if you want to make your code more clean. You can not make a code without iostream (or without any library) but you can without using namespace std simply by adding before every single line of function std:: Example (without using namespace std) std :: cout <<"without using namespace std"; std :: cin>>name; If you want more explanation let me know!
