Java程序计算数字的幂
从用户读取基值和指数值。将基数本身乘以基数，再将结果乘以基数（再次）重复n次，其中n是指数值。
2 ^ 5 = 2 X 2 X 2 X 2 X 2 (5 times)
示例
import java.util.Scanner;
public class PowerOfNumber {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
System.out.println("Enter the base number ::");
int base = sc.nextInt();
int temp = base;
System.out.println("Enter the exponent number ::");
int exp = sc.nextInt();
for (int i=1; i<exp; i++){
temp = temp*temp;
}
System.out.println("Result of "+base+" power "+exp+" is "+temp);
}
}输出结果
Enter the base number :: 12 Enter the exponent number :: 2 Result of 12 power 2 is 144
