The programming assignment is to create a “Long Integer” library with the following functions. Given as input N, the length of the integer in bytes, at run time, the following functions have to be implemented: 1. ADD(A, B) where A and B are signed numbers in N bytes, return the sum of A and B as an N byte number. 2. SUB(A, B) – similarly perform A – B. 3. MULT(A, B) – multiply A and B assuming the product is an N byte number. 4. Given M, an N byte number, 1. MOD-ADD(A, B, M) where the addition is done mod M. 2. MOD-SUB(A,B, M) similarly (note now there will be no possibility of negative numbers as in SUB). 3. MOD-MULT(A, B, M) where the product of A and B without the mod may be larger than N bytes.
