8.5.. Definisanje sporedne dijagonale.
Opis programa: Tabela sadži odnos indeksa sporedne dijagonale.
| red | i + j | Suma | Izraz | |
| 1 | 1 + n | = n + 1 | = n + 1 | |
| 2 | 2 + n - 1 | = n + 2 -1 | = n + 1 | |
| 3 | 3 + n - 2 | = n + 3 - 2 | = n + 1 | |
| ... | = n + 1 | |||
| n - 1 | 2 + n - 1 | = n + 2 -1 | = n + 1 | |
| n | n + 1 | = n + 1 | = n + 1 |
- Iznad sporedne dijagonale i + j < n + 1
- Ispod sporedne dijagonale i + j > n + 1
 |
| Slika 1. Sporedna dijagonala i+j = n+1 |
Listing programa :
package zadatak;
import java.util.Scanner;
class P08514050 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Unesi n ");
int n = input.nextInt();
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= n; j++) {
if (i + j == n +1)
System.out.print("x");
else
System.out.print("-");
}
System.out.println();
}
}
