using scanf instead of cin for multiple inputs

1. is it better to use scanf and printf instead of cin and cout? advantages of scanf and printf? 2. how to i get a pop-box in sololearn for the user to enter values with scanf or cin ? 3. is it possible to consolidate multiple inputs into scanf function or cin? #include <iostream> #include "stdio.h" using namespace std; int main() { int a, b; printf("enter a number! \n"); scanf("%d %d ", &a &b); int sum=a+b; printf("The value sum is %d\n", sum); //current output:The value sum is 2147344384 without the user being prompted to enter values for a and b. return 0; } Thank you, i appreciate your assistance

cin >> a >> b; Split multiple input into different lines, e.g. 3 4

printf and scanf is C Style syntax. It's better to use C++ syntax (cout, cin) if you're learning C++.
