Provided cstdio is included, both scanf() and printf() can be used in conventional C++ compilers but not in Code Playground You can also use std::cout and std::cin objects of iostream in C++ for output and input, respectively Learn more: https://www.sololearn.com/Course/CPlusPlus/?ref=app

std::cin>>variable; std::cout<<something; are most common

Example- cout << "Enter your age:"; cin >> age; cout << "\nYour age is: "<<age;

I always input using namespace std; it helps by making it so I don't need to type std over and over again. But I using cout and cin is good, you can add if functions for the cin, or just use cout<<a; while a is your answer.
