Draw an execution flowchart for the following statements and calculate the result of Sum and Counter after the loop:

1. Sum = 0 Counter = 1 Do While counter <= 100 Sum = Sum + Counter

Counter = Counter + 1

Loop

Messagebox.Show Sum = & Sum

Messagebox.Show Counter = & Counter

2. Sum = 0 Counter = 0 Do

Counter = Counter + 1 Sum = Sum + Counter

Loop Until Counter > 100

Messagebox.Show = Sum = & Sum

Messagebox.Show = Counter = & Counter

3. Sum = 0 For Counter = 1 TO 100

Sum = Sum + Counter

Next Counter

Messagebox.Show = Sum = & Sum

Messagebox.Show = Counter = & Counter
