Sir,

I want to multiply a 2-D array of size 100 by 100

a[100] * b[100];

or a[100][100];

What is the way to multiply the two arrays.

I want to know whether it is possible for the arrays to store the large result that would come out after sop much of maths.

But there should be some way.

If we can use pointer in the place of array is it possible

You need to be WAAAAAAAY more clear. Multiplication of two integers or floating point approximations is well-defined and everybody knows what you mean. Multiplication of arrays is not.

Do you want to make a multiplication table? That's one interpretation, and since you mentioned a two-dimensional array, that seems possible. However, there are other interpretations, such as dot product, or piecewise product. Or do you wish to perform matrix multiplication?

Unless you better explain what type of multiplication you want to do, you're not going to get a good answer.

You are writng c or c++ program NOT fortran. If you want the compiler to do high-level math then use a fortran compiler, which will PROBABLY do what you want (I don't know and don't care! :) ). When you write c and c++ code there are many things the compiler does NOT do for you -- you have to do them youself or get libraries where someone else did all the work for you.

there is situation like this:

main()

{

int a[100],b[100];

int i,j,k,n;

/* we have elements in a[100] = {1,2,3 .. 100}

we have elements in b[100] = {1,2,3 .. 100} */

Multiply the two numbers.

How to do the Multiplication.

}

Answer this.

Multiply the two numbers.

This makes no sense. There are two hundred numbers, and 10000 plausible combinations of them.
