What is the difference between variable assignment, variable initialization and dynamic initialization in C language?

Question

And when a variable is said to be uninitialised ?
Don't we say that in this case the variable is initialised with default values..?

Answer 1

Don't know how credible (or correct) this is, just what I found in regards to C (not C++) about dynamic initialization.
