5. Answer the following questions:
a. Who are the Programmers?
Answer: People who design the program in computer understandable language is called Programmer.
b. Give the steps to solve the problem.
Answer: There are three steps to solve a problem.
1. Algorithm
2. Flow chart
3. Program.
c. What are flow charts?
Answer: Pictorial representation of the step by step procedure to solve a problem is called a flow chart.
d. What is the different between a Flow chart and Algorithm?
Answer: Algorithm is a textual step by step procedure to solve a problem.
Flow chart is a pictorial representation of the step by step procedure to solve a problem.
e. What are the basic rules to create a flow chart?
Answer: Rules to make flow chart:
1. Flow of chart should be either top to bottom or left to right.
2. Arrow heads must be used with flow lines.
3. Crossing lines should be avoided.
4. If flow chart is using more than one page, connectors must be used.
f. What are the advantages of using flow charts?
Answer:
1. Problem solving is made simple.
2. It is easy to understand.
3. Data flow can be seen properly.
4. It is not based on any computer language.
5. Simple to make.
g. What are loops?
Answer: Loop is the way to represent the repeated steps again and again.
