Answer / kantilal

the diff b/w defination and declaration is
defination is allocating memory to the variable
ddeclaration is telling what type of variable it is and not
allocating memory for it

float y is defination as compiler allcates memory for it
if you give as extern float y it is declaration

Answer / vignesh1988i

this is declaration as well as definition....
according to me.,
DECLARATION here means that for some maniplation inside the
program we are going to use that variable y... but what is y
we want to tell the compiler so we are giving a new
DEFINITION to the alphabet as float DATA TYPE and thus we
are making the full variable


thank u

Answer / dally

defination is allocating memory to the variable.
but declaration is telling what type of variable it is and
not allocating memory for it.

Ex.int i;
extern int b;

here int i is definition because variable of value is
allocated in memory.
but variable b declared as int variable but memory is not
allocated for this.

float y is defination as compiler allcates memory for it
if you give as extern float y it is declaration

Write a C program that defines a 2-dimentional integer array called A [50][50]. Then the elements of this array should randomly be initialized either to 1 or 0. The program should then print out all the elements in the diagonal (i.e. a[0][0], a[1][1],a[2][2], a[3][3], ……..a[49][49]). Finally, print out how many zeros and ones in the diagonal.
