Question

JAVA 利用do...while循环计算1!+2!+3!+....100!的和。

Answer 1

public static void main(String[] args) {
//宴备后面数值太大 int 已经接收不了困信
int i = 0;
int j;
int sum = 0;
do {
i++;
System.out.println("--" + i + "--");

j = i;
int temp = 1;
do {

temp *= j;

System.out.print(j);

if (j > 1) {
System.out.print("*");
}

j--;

} while (j > 0);

System.out.print("="晌尺毁 + temp + "\n");

sum += temp;

} while (i < 100);

}
