4.5.4.Compute integer powers of 2 with while loop
using System; 
 
class MainClass {   
  public static void Main() { 
    int e; 
    int result; 
 
    for(int i=0; i < 10; i++) { 
      result = 1
      e = i; 
 
      while(e > 0) { 
        result *= 2
        e--; 
      
 
      Console.WriteLine("2 to the " + i + " power is " + result);        
    
  }   
}
2 to the 0 power is 1
2 to the 1 power is 2
2 to the 2 power is 4
2 to the 3 power is 8
