Printing variables to console

Question

Can someone explain difference in this 2 codes.

Console.WriteLine("Our total"+ total);

and

Console.WriteLine("Our total {0}", total);

Which of code is more or less correctly than other?

Answer 1

In this line

Console.WriteLine("Our total"+ total);

will always contact after left side of + sign is finish.

In this line

Console.WriteLine("Our total {0}", total);

will print where it's position is putted.

Like

Console.WriteLine("{0} is our total ", total);

This'll print first in the string.

if total is 10

Output :

10 is our total.

Both is correct but with different way of printing.
