Step by Step solution about How to resolve the algorithm Semiprime step by step in the C# programming language

The code snippet is a C# program that tests if a number is semiprime. A semiprime number is a natural number that is the product of two prime numbers. The program tests numbers from 0 to 49 and prints the result to the console.

The isSemiPrime function takes an integer as input and returns true if the input is semiprime, and false otherwise. The function works by iterating over all the numbers from 2 to the square root of the input, and checking if the input is divisible by any of these numbers. If the input is divisible by a number, then the function divides the input by that number and increments a counter. If the counter reaches 2, then the input is semiprime and the function returns true. Otherwise, the function returns false.

The main function of the program simply calls the isSemiPrime function for each number from 0 to 49 and prints the result to the console.

static void Main(string[] args)
{
    //test some numbers
    for (int i = 0; i < 50; i++)
    {
        Console.WriteLine("{0}\t{1} ", i,isSemiPrime(i));
    }
    Console.ReadLine();
}

//returns true or false depending if input was considered semiprime
private static bool isSemiPrime(int c)
{
    int a = 2, b = 0;
    while (b < 3 && c != 1)
    {
        if ((c % a) == 0)
        {
            c /= a;
            b++;
        }
        else
        {
            a++;
        };
    }
    return b == 2;
}
