C plus plus program to find prime number?
Here's an example. I've included analysis. #include<stdio.h> #include<stdlib.h> #include<math.h> int main(void) { /* User inputs high and low ends of range to search. / This could easily be done as function inputs, if / if so desired. */ int testprime,testdivisor, minprime, maxprime; printf("Search for primes between:\nLow end: "); scanf("%d",minprime); printf("Top end: "); scanf("%d",maxprime); int isprime; // 0 indicates a number is not prime.. for(testprime=minprime;testprime<=maxprime;testprime++) { isprime = 1; for(testdivisor=2;testdivisor<sqrt(testprime);testdivisor++) // Primes divide by 1! { isprime = testprime%testdivisor; // % finds remainders, so 7%3 returns 1. // If 0 is returned, a divisor has been found. if(isprime == 0) break; // Hence, not prime. "break;" exits the loop. } if(isprime != 0) printf("%d is prime.\n",testprime); } system("pause"); return 0; }
How to Write a function that counts the number of primes in the range 1-N?
Please check following link for primality test. http://en.wikipedia.org/wiki/Primality_testFollowing code is not in the optimized form...and it may contains some error please check it carefully before using ... int[] numbers = { 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 }; System.Collections.ArrayList PrimeNumbers = new System.Collections.ArrayList(); Boolean isPrime = false; for (int loop = 0; loop < numbers.Length; loop++) { int intNumberToTest = numbers[loop]; for (int intTest = 2; intTest
Prime number from 1 to N java?
private static boolean IsPrime(int Number) { int maxchk = (int) Math.ceil( Math.sqrt(Number) ); //makes it faster because we check less boolean isit = true; for (int i=2; i<=maxchk; i++) { if (Number % i ==0) isit=false; } return isit; } Simply call this from inside a for loop, EG for (int i=3; i<=N; i++) isPrime(i)
Is 895 a prime number?
No, 895 is not a prime number. The number 5 isprime, but any number ending in 5 (like 895) is divisible by 5, and cannot be a prime number.

How do you write a program to twin print prime numbers from 1 to 50 in PHP?
I suggest you write an outer loop, that loops through all the numbers from 1 to 50. Call the variable that controls the loop something like "number".Then, initially assume the number is a prime (with a variable such as "isprime"); and write another loop that compares whether the number is divisible by any number from 2 to number-1. Call the controlling variable "factor". If number is divisible by factor, then it is not a prime, and you can exit the loop. At the end of the inner loop, if the variable "isprime" is still true, then you print the number.
