How to make a string "transformed into a number"

I have an exercise to make the user type a word and it is transformed by their corresponding numbers from the ASCII table.

EXAMPLE : sara would print 115 97 114 97

this is the code:

NOTE: I put a fixed value in the vector just for testing. The result of this is causing two problems:

• At the time of rendering values, the first value (type prints ara and not sara )

• And also prints odd numbers like -14

  {
    int i;
    char texto[15] ;
  
    printf("digite uma palavra");
    gets(texto);
    fflush(stdin);
    scanf ("%c",texto);
  
    for (i=0; i<15; i++)
    {
      printf("Valor do elemento %d da string = %d\n",i, texto[i]);
    }
  
    getch();
  }
