C语言程序设计教程（第三版）课后习题10.7 （Java代码）

解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class Main {

public static void copy(char a[], int x) {

char b[] = new char[a.length - x + 1];

System.arraycopy(a, x - 1, b, 0, a.length - x + 1);

for (int i = 0; i < b.length; i++) {

System.out.print(b[i]);

}

}

public static void main(String args[]) {

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

String s = sc.next();

char a[] = new char[n];

for (int i = 0; i < s.length(); i++) {

a[i] = s.charAt(i);

}

int x = sc.nextInt();

copy(a, x);

}

}
