java刷题基础

1.++在前下先加后运算；++在后先运算后自加；

2.输入长度为n的数组，输出显示；

public static void main(String[] args) {

Scanner in = new Scanner(System.in);
 
int b = in.nextInt();
 
int[] c = new int[b];
 
for (int i= 0; i<b; i++){
 
    c[i] = in.nextInt();

}

for (int i= 0; i< b; i++) {
 
    System.out.print(c[i] + "  ");

}

}
