Answer all questions
1. “ In this generation, compiler was used to converts the entire source program into machine language before executing it. Programming languages that was used in this generation used English like words, and can be used on more than one type of computer. This language also can handle bigger and much complex problem. Examples of programming language in this generation were COBOL, Fortran, Basic, Pascal, C and Ada.”
Based on statements above,
(a) From what generation is the programming language mention above. [2]
(b) State the meaning of Programming Languages. [2]
(c) Other than compiler, state another two tools used by computers to converts the entire source program into machine language before executing it. [2]
(d) State TWO characteristic of programming languages in fourth generation languages (4GL).
[2]
2. Below is an algorithm to solve a mathematical problem in getting the biggest number and average number from three given numbers.
1. Start
2. Read X
3. Read Y
4. Read Z
5. Total = X + Y + Z
6. Average=Total / 3
7. If X > Y and X > Z then Biggest =X, goto line 10
8. If Y > X and Y > Z then Biggest =Y, goto line 10
9. If Z > X and Z > Y then Biggest =Z, goto line 10
10. Display Average
11. Display Biggest
12. End
(a) Define the meaning of ALGORITM [2]
(b) There are TWO types of algorithm. State and briefly explain both of the algorithm. [4]
(c) Based on algorithm above, draw a suitable flowchart diagram. [12]

Question 8 based on Diagram 2 below.
DIAGRAM 2
8. From diagram 2,
(i) List three identifiers which have global scope. [3 marks]
(ii) List three identifiers which have local scope. [3 marks]
(iii) State two differences between global scope identifier and local scope identifier. [2 marks]
(iv) Given the value of num1 is 200, num2 is 300 and num3 is 500. If one instruction as below is put in line Z, what is the value return to the main program ? [2]
Instruction to be put in line Z : addnumber=addnumber*A+B+C
