If I want to initialize elements in an array (to a value),
is using for loops the only method??

Is there any specific functions to do that??

icic~
so that's the same as Java~

You can use initialiser lists when you define your array e.g.

int array[5] = { 1, 2, 3, 4, 5 };

I often use memset to zero arrays.

To add  -
If you wish to only init few items then you may use :
int x[5] = {9, 3};
In the above example, only the first two elements are set to the values
mentioned, most compilers do initialise the rest of the elements to
zero.
Though, not sure what the ANSI "C" standards book says about the init
of the remaining elements.

To add _to what_? Learn to use Google Broken Beta properly, get it to
provide a proper quotation, or get a real newsreader!

Not most. All. The Standard requires it.

This is guaranteed.

In the case of a partially-initialised aggregate or union object,
"all subobjects that are not initialized explicitly shall be
initialized implicitly the same as objects that have static
storage duration." - 6.7.8(19).

"If an object that has static storage duration is not initialized
explicitly, then:
� if it has pointer type, it is initialized to a null pointer;
� if it has arithmetic type, it is initialized to (positive or
  unsigned) zero;
� if it is an aggregate, every member is initialized (recursively)
  according to these rules;
� if it is a union, the first named member is initialized (recursively)
  according to these rules." - 6.7.8(10).
