how do i make my program take very large positive numbers without using double precision integer type. for instance:
 
the user should be able to enter a number like:
5245456638463644648646486464348443466648436446
 
and get something like:
4243545636758689184912673254783849162783326564 as its quotient and 76586798707897 as its remiander.
 
i’ll also like to know if its never possible to get that using just “int type”. thanx to all.

Usually what is done in this case is one is required to write a large number module for your program. A array of the smallest integer type on your machine is usually used ( a short type or something like that ). You will usually use an array like:
 
short largeNumber [ NUMBER_OF_DIGITS ];
 
and then you will represent large numbers like:
 
12345….
 
largeNumber [ 0 ] = 1

largeNumber [ 1 ] = 2

largeNumber [ 2 ] = 3

largeNumber [ 3 ] = 4

largeNumber [ 4 ] = 5
……..
 
then you write functions to read , write and do mathematical computations on the arrays like:
 

int * num;<br /> int * num2;<br /> int * sum;<br />  <br /> initialize ( num , size ); //allocate memory<br /> initialize ( num2 , size ); //allocate memory<br />  <br /> sum = add ( num , num2 ); //sum 2 large numbers<br />  <br /> printf ( "the sum is n" );<br /> printLargeNumber ( sum ); //output sum<br />  

1 2 3 4 5 6 7 8 9 10 11 12

int * num;<br /> int * num2;<br /> int * sum;<br />  <br /> initialize ( num , size ); //allocate memory<br /> initialize ( num2 , size ); //allocate memory<br />  <br /> sum = add ( num , num2 ); //sum 2 large numbers<br />  <br /> printf ( "the sum is n" );<br /> printLargeNumber ( sum ); //output sum<br />
