How to write scanf(“%f”, &a); on C++

Question

I tried to write cin>>&a;
But it’s wrong

Answer 1

In c++ no need the “&”!
Just use cin >> a;

Answer 2

float a;
cin >> a;
// In C++, we don't need to specify the access specifiers like %d, %f, %c, etc. And also we don't need to use '&' symbol while taking input from the user.
