Come si fa a stampare il p-esimo valore di un vettore v (diciamo di N interi)?
for ( i = 0; i < N; i++ )
if ( i == p ) printf( "%d", v[ i ] );
else printf( "non trovato" );
E si stupiva pure che stampasse N-1 volte "non trovato"!
La giustificazione: "credevo che l'unico modo per accedere ai valori del vettore fosse usare l'espressione v[ i ]"… detto altrimenti: pensava che tra le quadre ci si potesse mettere solo i!
