What is the significance of 0.0f when initializing (in C)?

Question

I\'ve seen code where people initialize float variables like this:

float num = 0.0f;

Is there a significant difference between this and jus

Answer 1

It's just considered good practice to initialise a variable with a literal constant of the same type. In this case you have a float variable and you should initialise it with a float literal constant, i.e. 0.0f, rather than an int (0) which is then implicitly cast to a float.
