Sum of Array

Algorithm

  1.   Start
  2. a[]=null
  3. b[]=null
  4. sum[]=null
  5. i:=0
  6. n:=0
  7. Print "Enter the length of both the array"
  8. Read n
  9. a=new int[n]
  10. b=new int[n]
  11. sum=new int[n]
  12. i=0
  13. If i<n, go to step 14 or else go to step 19
  14. Print "Enter a number in the first array"
  15. Read a[i]
  16. Print "Enter a number in the second array"
  17. Read b[i]
  18. i++. Go to step 13
  19. i=0
  20. If i<n, go to step 21 or else go to step 23
  21. sum[i]=a[i]+b[i]
  22. i++. Go to step 20
  23. i=0
  24. If i<n, go to step 25 or else go to step 27
  25. Print sum[i]
  26. i++. Go to step 24
  27. Stop

Conversion of Complex Sentences to Simple Sentences

In this blog, we shall look at the various methods applied for the conversion of a Complex Sentences to Simple Sentences . The following examples have been taken from the english language textbook prescribed for ISC students studying in class 11. Use these as practice and climb your stepping stones to better grammar! A complex sentences can be converted to a simple sentence by changing a noun clause, an adjective clause or an adverb clause, as shown below: Noun Clause Complex:Tell me where you live. Simple:Tell me your address. Complex:That you should be present is essential. Simple:Your presence is essential. Adjective Clause Complex:Time which is once lost is lost forever.

Simple:Having finished his work, he went out to play. Complex:If I make a promise, I will ke

Conversion of Compound Sentences to Complex Sentences.

In this blog, we shall see the rules and guidelines that govern the conversion of compound sentences to complex sentences. The examples given below are taken from the assignment given in section B of Unit 2 in the English Language textbook prescribed for ISC class 11.  It is possible to change a Compound Sentence to a Complex sentence by changing one of the Coordinate Clauses to a Subordinate Clause. Coordinate Clause-  one of two or more clauses in a sentence that are of equal importance and usually joined by  and, or , or  but. Subordinate clause -  a clause, typically introduced by a conjunction, that forms part of and is dependent on a main clause. Compound: He is industrious but he is dull. Complex:He is industrious though he is dull. Compound:Act on my advice or you will come to grief. Complex:If you do not act on my advice, you will come to grief. Assignment Compound:Ask no questions and you will hear no lies. Complex: If you ask no questions, you will hear no
