Programming in C : A small note on arrays

The subscript of an array can be ' an expression ' which yields integers. Note that any reference to the array outside the declared limit would not necessarily cause an error.

If array size declared as 10 , then we declare first element to zero , as

int array [10] = {10} ;

then all elements are declared as zero automatically.

Here is an example of wrong declaration to an array.

char alpha [3] = {a,b,c} .

If you want to store alphabets into an array store its integer values ,

char alpha [3] = { 'a' , 'b' , 'c' }
and print them as characters.
