If the program expects to receive the values through the standard input, what you can do is redirect said entry to a file.

The batch would look like this:

sumar < entrada.txt

If you want to provide the values directly from the batch you have to modify your program to read the input parameters:

batch:

sumar 10 20

C:

int main(int argc, char** argv)
{
  int a, b;
  if( argc == 3 )
  {
    a = strtol(argv[1],NULL,10);
    b = strtol(argv[2],NULL,10);
  }
  else
  {
    printf("Introduce dos números:\n");
    scanf("%d %d",&a,&b);
  }

  printf("El resultado es %d\n",a+b);
}
