Institute of Engineering‚ Information and Technology Structure of Programming Language “C++ Programming Language” INSTRUCTOR: SCLP SUBMITTED BY: UC HISTORY OF C++ In the early 1970s‚ Dennis Ritchie of Bell Laboratories was engaged in a project to develop a new operating system. Ritchie discovered that in order to accomplish his task he needed the use of a programming language that was concise and that produced compact and speedy programs. This need led Ritchie to develop the

world of data structures and algorithms Bit-Sum Prime Difficulty level: moderate Every student‚ who has learned programming‚ must have written a program to determine whether a given positive integer is a prime number. Basically in order to determine whether a positive integer n is prime‚ we search for any number in the range [2‚ n − 1] which can divide n. Some of you would have designed a slighly better implementation where you search √ for any divisor of n from the range [2‚ n ]

(osler@rowan.edu) Rowan University‚ Glassboro‚ NJ 08028 Fermat’s Little Theorem [1] states that n p −1 − 1 is divisible by p whenever p is prime and n is an integer not divisible by p. This theorem is used in many of the simpler tests for primality. The so-called multinomial theorem (described in [2]) gives the expansion of a multinomial to an integer power p > 0‚ (a1 + a2 + ⋅⋅⋅ + an ) p = p k1 k2 kn a1 a2 ⋅⋅⋅ an . k1 ‚ k2 ‚ ⋅⋅⋅‚ kn k1 + k2 +⋅⋅⋅+ kn = p ∑ (1) Here the multinomial

Linear Application and Hill Cipher. Cryptography has played an important role in information and communication security for thousand years. It was first invented due to the need to maintain the secrecy of information transmitted over public lines. The word cryptography came from the Greek words kryptos and graphein‚ which respectively mean hidden and writing (Damico). Since the ancient days‚ many forms of cryptography have been created. And in 1929‚ Lester S. Hill‚ an American mathematician and

as the specific topic I would like to go deep into. Fermat ’s Last Theorem states that if n is a positive integer greater than 2‚ then the Diophantine equation x^n+y^n=z^n has no nontrivial solutions. Diophantine equation is an equation together with the restriction that the only solutions of the equation of interest are those belonging to a specified set‚ often the set of integers or the set of rational numbers. Fermat ’s last theorem has its origins in the mathematics of ancient Greece; two
