Question
Draw flow charts for each of the following programming constructs (2 Marks each)
- If statement
- If - else statement
- For loop
- While loop
- Do-while loop
Solution
Here are the flow charts for the specified programming constructs:
1. If Statement
+---------------------+
| Start |
+---------------------+
|
v
+---------------------+
| Condition Check |
+---------------------+
|
+---------+----------+
| |
v v
+--------------+ +----------------+
| True | | False |
+--------------+ +----------------+
| |
v v
+---------------------+ +---------------------+
| Execute Statements | | End/Next Statements|
+---------------------+ +---------------------+
|
v
+---------------------+
| End |
+---------------------+
2. If-Else Statement
+---------------------+
| Start |
+---------------------+
|
v
+---------------------+
| Condition Check |
+---------------------+
|
+---------+----------+
| |
v v
+--------------+ +----------------+
| True | | False |
+--------------+ +----------------+
| |
v v
+---------------------+ +---------------------+
| Execute True | | Execute False |
| Statements | | Statements |
+---------------------+ +---------------------+
|
v
+---------------------+
| End |
+---------------------+
3. For Loop
+---------------------+
| Start |
+---------------------+
|
v
+---------------------+
| Initialize Counter |
+---------------------+
|
v
+---------------------+
| Condition Check |
+---------------------+
|
+---------+----------+
| |
v v
+--------------+ +----------------+
| True | | False |
+--------------+ +----------------+
| |
v v
+---------------------+ +---------------------+
| Execute Statements | | End/Next Statements|
+---------------------+ +---------------------+
| |
v |
+---------------------+ |
| Update Counter |<---+
+---------------------+
|
v
+---------------------+
| End |
+---------------------+
4. While Loop
+---------------------+
| Start |
+---------------------+
|
v
+---------------------+
| Condition Check |
+---------------------+
|
+---------+----------+
| |
v v
+--------------+ +----------------+
| True | | False |
+--------------+ +----------------+
| |
v v
+---------------------+ +---------------------+
| Execute Statements | | End/Next Statements|
+---------------------+ +---------------------+
|
v
+---------------------+
| Condition Check |
+---------------------+
|
v
+---------------------+
| End |
+---------------------+
5. Do-While Loop
+---------------------+
| Start |
+---------------------+
|
v
+---------------------+
| Execute Statements |
+---------------------+
|
v
+---------------------+
| Condition Check |
+---------------------+
|
+---------+----------+
| |
v v
+--------------+ +----------------+
| True | | False |
+--------------+ +----------------+
| |
v v
+---------------------+ +---------------------+
| Loop Again | | End/Next Statements|
+---------------------+ +---------------------+
|
v
+---------------------+
| End |
+---------------------+
These flow charts illustrate the logical structures of the respective programming constructs. Adjust the visual representation or layout as per your preference for clarity.
