Will the for loop execute without initialization? Explain with examples.

Answer 1

With "initalization" do you mean keeping the whole part in the parentheses empty:
for (;;) {...}

Or just the first statement:
for (; i < 10; i++) {...}

?

Anyways both would be valid to use, but...

In the first example you would create an infinite loop, but you can fix this with a break statement.

In the second example you still need to define variable i before the loop execution, for example:
int i = 0;
for (; i < 10; i++) {...}

Otherwise an error will happen.

You joined multiple courses, how to know which language you mean?
