For the program on slide #18 mark out the:
Repeat Exercise 1 for the program on slide #22.
Repeat Exercise 1 for the program on slide #35.
Refer to the program on slide #36. What difference would you expect if we change
for ($n=0; n<$so_many_times; $n++)
for ($n=-100; n<$so_many_times-100; $n++)
for ($n=$so_many_times+1000; $n>1000; $n--)
for ($n=0; n<$so_many_times*1000; $n+=1000)
Refer the program on slide #36. What happens if we change

Write a program to generate two random numbers between 0 and 100. Print the larger number, and the sum, difference and product of the two numbers.
Write a program to generate a random number between 0 and 10. Take the number as the radius of a circle. Print the diameter, circumference and area of this circle.
Write a program to generate a random number 1930 ≤ y ≤ 2017, take this as somebody's year of birth. Generate another random number 1 ≤ m ≤ 12, let this be his month of birth. We need to know his age in the coming years until he reaches 90. Print your output in three columns:
__ years __ months
90 years 0 month
