There is a difference between prime numbers and co-prime numbers.

Numbers greater than 1 having at least three factorsĢ is the smallest and the only even prime numberĮxamples of prime numbers are 2, 3, 5, 7, 11, 13, and so on.Įxamples of composite numbers are 4, 6, 8, 9, 10, and so on. Numbers, greater than 1, having only two factors, 1 and the number itself Let us understand the difference between prime numbers and composite numbers with the help of the table given below:

For example, 4 can be factorized in multiple ways.

A composite number is a number greater than 1 that has more than two factors.

It has only two factors, which are, 1 and 5. For example, 5 can be factorized in only one way, that is, 1 × 5 (OR) 5 × 1.

A prime number is a number greater than 1 that has exactly two factors, while a composite number has more than two factors.

The following example demonstrates the Join method. ' The example displays the following output: If values(0) Is Nothing Then values(0) = String.EmptyĬonsole.WriteLine(String.Join('|', values)) using System Ĭonsole.WriteLine('Primes less than It assigns the result to a List object of type String, which it then passes to the Join(String, IEnumerable) method.

The following example uses the Sieve of Eratosthenes algorithm to calculate the prime numbers that are less than or equal to 100. The length of the resulting string overflows the maximum allowed length ( Int32.MaxValue). Overloads Join(Char, Object)Ĭoncatenates the string representations of an array of objects, using the specified separator between each member.Ĭoncatenates an array of strings, using the specified separator between each member.Ĭoncatenates the members of a constructed IEnumerable collection of type String, using the specified separator between each member.Ĭoncatenates the elements of an object array, using the specified separator between each element.Ĭoncatenates all the elements of a string array, using the specified separator between each element.Ĭoncatenates an array of strings, using the specified separator between each member, starting with the element in value located at the startIndex position, and concatenating up to count elements.Ĭoncatenates the specified elements of a string array, using the specified separator between each element.Ĭoncatenates the members of a collection, using the specified separator between each member. Concatenates the elements of a specified array or the members of a collection, using the specified separator between each element or member.
