# Write a program to print prime numbers in c language

The exponents listed by Mersenne were as follows: Main function Every C program is started from main function and this function contains two major sections called declaration section and executable section.

A notable contribution was made by retired Yale physics professor Horace Scudder Uhler, who did the calculations for exponents,and See the screen shot below. His list replicated the known primes of his time with exponents up to The prime was found on a Dell OptiPlex on August 23, Example C programs with definition, example program and output: What ever data we pass through the enclosed parentheses of printf function will get printed on the output screen and the data can be integers,characters or strings.

Now you will see the output screen as shown in the screen shot below. All composite divisors of prime-exponent Mersenne numbers are strong pseudoprimes to the base 2. This was the largest known prime number for 75 years, and the largest ever found by hand.

Global declaration section Global variables are defined in this section. Make your program free of errors before you RUN the program.

Here in this program this getch function is used as a trick to hold the output screen live for a desired period of time by the user.

Mersenne gave little indication how he came up with his list. The find was verified on June 12, The best method presently known for testing the primality of Mersenne numbers is the Lucas—Lehmer primality test. Let us see about each section of a C basic program in detail below.

There are exceptions in some cases like usage of loops for, do while etc which we will learn later. After nearly two centuries, M31 was verified to be prime by Leonhard Euler in However, since p is congruent to 3 mod 4q is congruent to 7 mod 8 and therefore 2 is a quadratic residue mod q.

A Mersenne prime cannot be a Wieferich prime. Mersenne primes take their name from the 17th-century French scholar Marin Mersennewho compiled what was supposed to be a list of Mersenne primes with exponents up to There is a lot of process that happens while the compiler compiles a program — which we will discuss later in coming articles.

Sections Description Documentation section We can give comments about the program, creation or modified date, author name etc in this section. This is a C basic program Sum of two numbers: After compiling, you will see a dialog box as shown below.

Alan Turing searched for them on the Manchester Mark 1 in[9] but the first successful identification of a Mersenne prime, M, by this means was achieved at His next entry, 31, was correct, but the list then became largely incorrect, as Mersenne mistakenly included M67 and M which are composite and omitted M61, M89, and M which are prime.

Powers in andrespectively. M is the first Mersenne prime that is titanicM44, is the first giganticand M6, was the first megaprime to be discovered, being a prime with at least 1, digits.
