Design a pseudocode and a flowchart to input three numbers,find their total and average,and print both numbers.

sum=0

for i=1 to 3
read n
sum += n

avg = sum/3

print sum, avg

Sure! Here's a pseudocode and flowchart to solve the given problem:

Pseudocode:
1. Start
2. Declare variables num1, num2, num3, total, average
3. Read input for num1, num2, and num3
4. Calculate total = num1 + num2 + num3
5. Calculate average = total / 3
6. Print num1, num2, num3, total, and average
7. End

Flowchart:
+---------+
| Start |
+---+-----+
|

| Input num1 |
+---+---------+
|
|
v
+---- ----------+
| Input num2 |

v
+-------------+
| Input num3 |
+-------------+
|
|
v
+-----------------------+
| total = num1 + num2 + num3 |
+-----------------------+
|
|
v
+-------------------+
| average = total / 3 |
+-------------------+
|
|
v
+-----------------------+
| Print num1, num2, num3 |
| Print total |
| Print average |
+-----------------------+
|
|
v
+---------+
| End |

I hope this helps!
