Algorithm

• An algorithm is just a detailed sequence of simple steps that are needed to solve a problem

• Flowchart is the graphical representation of an algorithm

Flowchart

Steps to create an algorithm

• First produce a general algorithm

• Refine the algorithm successively to get step by step detailed algorithm that is very close to a computer language.

Pseudo code

• Pseudo code:Pseudo code is an artificial and informal language that helps programmers to develop algorithms. Pseudo code is very similar to everyday English.

• Input a set of 4 marks• Calculate their average by summing and dividing by 4• if average is below 50

Print “FAIL”else

Print “PASS”

Detailed Algorithm Step 1: Input M1,M2,M3,M4

Step 2: GRADE (M1+M2+M3+M4)/4 Step 3: if (GRADE < 50) then

Print “FAIL” else

Print “PASS”end

Name Symbol Use in Flowchart

Denotes the beginning or end of the program

Denotes an input operation

Denotes an output operation

Denotes a decision (or branch) to be made. The program should continue along one of two routes. (e.g. IF/THEN/ELSE)

Denotes a process to be carried oute.g. addition, subtraction, division etc.

Flow line Denotes the direction of logic flow in the program

Example• START

• Input• M1,M2,M3,

M4

• GRADE(M1+M2+M3+M4)/4

• If • GRADE<

50

• PRINT• “FAIL”

• STOP

• Y• N

PRINT“pass”

Step 1: Input M1,M2,M3,M4Step 2:GRADE (M1+M2+M3+M4)/4 Step 3: if (GRADE <50) then

Print “FAIL” else

Print “PASS” end

Example

ALGORITHM

Step 1: Input A,BStep 2: if (A> B) then

MAX Aelse

MAX Bend

Step 3: Print “The largest value is”, MAX

• The expression A>B is a logical expression

• it describes a condition we want to test

• if A>B is true (if A is greater than B) we take the action on left

• print the value of A

• if A>B is false (if A is not greater than B) we take the action on right

• print the value of B

Flowchart

• MAX A

• Print• “The largest value is”, MAX

• STOP

• Y • N

• START

• Input• A,B

• MAX B

• if• A>B
