user'll only be able to enter predetermined vals
<code>
#include <iostream>
using namespace std;
int main
{
char A[12]="47000000000";
char B[12]="47000000000";
char C[12]="47000000000";
cout << "Enter 3 numbers to multiply(1-13 digits): ";
cin >> A[11];
cin >> B[11];
cin >> C[11];
char D[39]="10382300000000000000000000000000000000";
cout << D << D[38] << endl;
cin >> D[38];
}
</code>
What changes should I make to the computer program above
to allow the user to enter any values that fits within the
array sizes: [12] , [12] , [12] , [39] .

You can use

I did use (code tags) you should have paid attention to the contents of my first post!
Because if you did, you would see them right where they need to be.

@cppnerd. Your Post Does not have code tags in any way shape or form. Look closer...
With Code tags:
Without:
int x = 5;

code tags are used by [ code ] [ /code ] (ignore the white spaces) and not by <code> </code>
I think your habit of using <> is because of html, isn't it @cppnerd?

What is that? Not a legal C++ type I am sure.
There are external libraries like GMP and many others, that will handle arbitrarily large integers. Check out Boost as well.

Hope all is well :+)
I believe this is what you're looking for:

yes he does. they just arent cplusplus.com compliant.

certainly not.

No. Look up the maximum value for that type and see how many digits it has :+)
One needs a library to do this because the largest unsigned value (64 bit) is still not big enough.

Well, on a 64 bit machine
But it is better to use a

cstdint.h type like uint64_t (platform independent). The maximum is still 64 bit which is about half of what the OP requires.Topic archived. No new replies allowed.
