Pseudocodes in PHP

[fayerie13]

Please kindly help with pseudocodes for the following - I do not know where to start:

 

- An algorithm to calculate the sum of even and odd numbers less than 10 and store the values in EVEN and ODD respectively:

 

- An algorithm to calculate the product of all the numbers greater than 0 and less than 5.

 

- An algorithm to calculate how many days are in a given number of years. ie. for 2 years, the number of days equals to 730

Do you understand what pseudo-code is? What have you tried? Where did you get stuck?

Do you understand what pseudo-code is? What have you tried? Where did you get stuck?

@Guru  I understand that pseudo code is a notation resembling a simplified programming language, used in program design.this is what I have so far - I am not sure if I am going the right direction though:

 

//an algorithm to calculate the average of any number of integers

$array = set of numbers

average = sum $array / count numbers $array

print average result

 

//calculate sum of even and odd numbers less than 10 and store values into even and odd respectively

$number = 0

 

for function (number = 0; work with numbers <10; increment number){

if ($number is divisible by 2)

print 'number is even'

}

else

print 'number is odd'

 

number = range between 0 - 10

print sum of numbers

 

//calculate the product of all the numbers greater than 0 and less than 5

I don't know whether to use the while loop or the for loop for this?

 

 

//calculate how many days are given in number of years

function to get how many days in (certain year)

 

number of days = array of numbers

total month = 12

if ($year) is equal to date (y)

total month = date (m)

else

total month is = 12

 

use for loop function (month = 1; m is less than and equal to total month; increment m)

number of days = calculate days in a month using cal_gregorian function, m, $year

 

return number of days

 

number of days = get days for (certain year)

use print_r(number of days)

I think some of your solutions miss the point, and some are simply wrong.

 

The point of your exercise is to write a concrete algorithm which does exactly what the description says (and nothing more). So when you're asked to store the sum of odd numbers in ODD and the sum of even numbers in EVEN, they clearly don't want you to write print statements or vague “sum of numbers” commands. They want the specific steps:

// initialize variables for sums
odd := 0
even := 0

// calculate sums
for i from 1 to 9:
  if i is odd:
    odd := odd + i
  else:
    even := even + i
