Your code is filled with C++isms that cause errors in C. This compiles, but I didn't test it for logic errors:

Code:

#include <stdio.h>
#include <stdlib.h>

typedef struct Student
{
  int x;
  struct Student * Next;
}Student;

int main()
{
  int Choice;
  int Salir;
  Student* Head;
  Student* Dummy2;
  Student Dummy;
  Dummy2=(Student*)malloc(sizeof (Student) );
  Head=(Student*)malloc(sizeof (Student) );
  Head->Next=0;
  Dummy2->Next=0;
  Choice;
  Salir=0;

  for (;;)
  {

    printf("Que desea hacer\n");
    printf("1)Insertar Estudiante\n");
    printf("2)Ver Estudiantes\n");
    printf("3) Salir\n");
    scanf("%d",&Choice);

    switch (Choice)
    {
    case 1:
      {

        printf("Get Student's Age\n");
        scanf("%d",&Dummy.x);

        if (Head->Next==0)
        {
          Head=&Dummy;
        }

        else  
        {
          Dummy2=Head;
          while(Dummy2->Next!=NULL)
          {
            Dummy2=Dummy2->Next;
          }
          Dummy2->Next=&Dummy;


          printf("AGe %d",Dummy.x);

        }

        break;
      }

    case 2:
      {
        Student* TempHead;
        TempHead=(Student*)malloc(sizeof (Student) );
        TempHead=Head;
        while (TempHead->Next!=NULL)
        {
          printf("head age %d",TempHead->x);
          TempHead=TempHead->Next;
        }

        break;
      }


    case 3: Salir=1;
      break;
    }

    if (Salir)
      break;

  }

  return 0;
}
