Ejercicios tarea autonoma

  1)    Escribir un programa que lea un vector de 10 elementos. Deberá imprimir el mismo vector por pantalla

pero invertido. Ejemplo: dado el vector 1 2 3 4 5 6 7 8 9 10 el programa debería imprimir 10 9 8 7 6 5 

4 3 2 1.

    Console.WriteLine("Ingrese un número de 10 digitos");
long num = long.Parse(Console.ReadLine());
String s = "";

while (num != 0)
{
s += num % 10;
num /= 10;
}

Console.WriteLine(s);
Console.Read();
} 
            }
        }

2)Escribir un programa que lea 10 números por teclado. Luego lea dos más e indique si éstos están entre

los anteriores.

3)Escribir un programa que pida 10 números enteros por teclado y que imprima por pantalla:

i. Cuántos de esos números son pares. 

ii.Cuál es el valor del número máximo. 

iii.Cuál es el valor del número mínimo.
