Homework 4 Due: Monday, November 27

1. Consider the following array declaration in Pascal. Write a Pascal assignment statement to set the first element of the array to 15. Write a Pascal assignment statement to set a variable Foo to the value of the seventh element of the array.

Question1: array (-5..11) of integer;

2. Consider the following record declaration in Pascal. Write a Pascal assignment statement to set Calories_Consumed to 101.3.

Training_Run: record

Distance: real;

Time: real;

Effect: record

Calories_Consumed: real;

Felt_Good: boolean;

End;

Month: integer;

Year: integer;

End;

3. How many times does the following Pascal loop execute (how many values for Quant are printed out by the writeln statement)? The writeln statement is just a mechanism to print values out on the screen of the computer.
   Quant := 1;
   Ctr := -5;
   while Ctr < 10 do
   begin
   if (Ctr < 0)

then Quant := Quant * 10;
writeln (Quant);
Ctr := Ctr + 2

end;


4. How many times does the following Pascal loop execute?
   Sum := 0:
   for I := 6 to 20 by 3 do
   Sum := Sum + I;
   writeln (Sum);
   
5. Why is a compiler referred to as a "translator?"
   
6. How can the evolutionary software development model sometimes produce software systems that satisfy customer needs at less cost and in less time than other methods?
