Code - Finding GCD of array

your welcome

Hi

 

i modify the code 

 

public class Class2
{
static void Main(string[] args)
{

int[] input = new int[5];
Console.WriteLine("Please enter the number");

for (int i = 0; i {
string line = Console.ReadLine();
int value;
if (int.TryParse(line, out value))
{


input[i] = value;


}
else
{
Console.WriteLine("Not an integer!");
}

}




//int[] input = Convert.ToInt32(Console.ReadLine());
int output = UserProgramCode.GCD(input);
}
class UserProgramCode
{
public static int GCD(int[] array)
{
int a = 0, b = 0, gcd = 0, t;
for (int i = 0; i < array.Length - 1; i++)
{
a = array[i];
b = array[i + 1];
while (b != 0)
{
t = b;
b = a % b;
a = t;
}
gcd = a;
}
return gcd;
}
}

} 

Thanks for your reply Ravi. 

 

Here in the above code you have initialized the array as int[5], here mandatory it asks to enter number 5 times. 

 

This is dynamic, sometimes user want to find GCD for 2 numbers or sometimes for 5 numbers.

 

And need to check only intergers are given as input, not letters.  

 

How can i modify for this requirement.

 

Please suggest. 

Hi,

 

public class Class2
{
static void Main(string[] args)
{
Console.WriteLine("Please enter the number");

int[] input = new int[5];
for (int i = 0; i < input.Length; i++)
{
input[i] = Convert.ToInt32(Console.ReadLine());
}
//int[] input = Convert.ToInt32(Console.ReadLine());
int output = UserProgramCode.GCD(input);
}
class UserProgramCode
{
public static int GCD(int[] array)
{
int a = 0, b = 0, gcd = 0, t;
for (int i = 0; i < array.Length - 1; i++)
{
a = array[i];
b = array[i + 1];
while (b != 0)
{
t = b;
b = a % b;
a = t;
}
gcd = a;
}
return gcd;
}
}

}

 above code is working now  check it
