Thread: For Loops

Hi guys. Hope you are well. I'm particularly stuck on understanding for loops properly. I have this program which computes numbers to whatever power you want it to. There are two command line arguments, the first being the number and the second being the power:

 
public class Power
{
  public static void main(String [] args)
  {
    int number = Integer.parseInt(args[0]);
    int power = Integer.parseInt(args[1]);
    int answer = 0;
 
    for (int i = 0; i*i < power; i++)
      answer=number*power;
    System.out.println(answer);
 
  }
}

Can anyone help on correcting this problem and possibly explaining how the for loop works, because i'm so confused :S

Kind regards

Shyam

Read books to learn how to use "for loop".....

Try to manipulate your answer on book.
Like i=0;i<power;i++
Calculating :- answer=number*power; suppose number is 2 and power is 5
for loop condition is satisfied
answer= 2*5 (= 10); after this increment i=1;
answer=10*5 (=50).....ans so on

actual answer or For loop should be
answer=(your number)(assign your number to answer);
for(int i=1;i<power;i++)
answer=answer*number;


print answer ;
