Question

Write pseudocode and draw flowchart to accept numbers till the user enters 0 and then find their average.

Answer 1

Pseudocode is as follows: 

Step 1: SET count = 0, sum = 0 

Step 2: INPUT num 

Step 3: WHILE num is not equal to 0, REPEAT Steps 4 to 6 

Step 4: sum = sum + num 

Step 5: count = count + 1 

Step 6: INPUT num 

Step 7: COMPUTE average = sum/count 

Step 8: PRINT average 

The flowchart representation is shown in Figure.

Flowchart to accept numbers till the user enters 0

we do not know how many numbers a user is going to enter before entering 0. This is handled by checking the condition repeatedly till the condition becomes false.
