Tutorial 3

1. Write a Pascal program to show an output below

12 * 2= 24

.........

12 * 12 = 144

by using control structures, i.e., while...do, repeat...until, for...to...do

2. Write a Pascal program to find a summation of the following sequence

5 + 12 + 19 + ......+ 278

3. Write a Pascal program to verify an integer received from a keyboard. If the integer is in a range from -3 to 3, show the output corresponding to the received integer as the table below

-3	GO
-2	WENT
-1	GONE
0	SEPARATE
1	DONE
2	DID
3	DO

If that integer is in the range, return to receive a new value.

4. Write a Pascal program that will receive 20 integer variables. Find the maximum and minimum values of this set of variables.

5. Write a Pascal program to find the summation of a sequence below

y = -(1/1^2) + (1/2^2) - (1/3^2) + (1/4^2) -.....

Hint: Use operator MOD to verify that n is odd or even number.

6. Write a Pascal program that has a function
                q(a,b) = 0 , for a < b
                          = q(a-b,b) , for a >= b
In your program, you must receive value a and b and send these values to your function. Check your result with the following example.
                q(14,3) = 4
                q(5861,7) = 837
