Zhen Yu's Not-In-Slides Hints

How do we know whether to print IN the indentation or OUTSIDE the indentation?

For counting values : placing the PRINT in the indentation causes the PRINT to be PRINTed for that number of times. So its good for counting values (1,2,3,4,5.... etc)

For sums : should be placed OUTSIDE the indentation. The loop calculates the values, then you SUM the end of the loop process.

the termination can be placed before the print no problem right man -calvin
thanks

Zhen Yu's Not-In-Slides Hint 2

The second step of a loop involves BOTH the decision and termination (NOT only termination) as termination is just the last part of the decision. Hence, they occupy the same symbol in a flowchart

When using Trace Table, a good format of data to use is:
Normal data
Boundary data
Abnormal data

For example my While statement uses i > 1 and i <=10, so use this format to fill in your Trace Table
Normal data (3,4,5,6,7,8,9)
Boundary data (2,10)
Abnormal data (-1,11)

How to do explanation for the trace table?-huiteng

What is wrong with this anybody check for me pls.

Do we need to include the function: else in the write function if there is no code for the else part? Zhen Yu

2021-05-19 06:10:36 UTC

for example 12b where there is no need for an else , do we just put an if and leave it as it is?

What are the datatype that are shown in the "problem to solve"? (optional)

requires a "valid counter" variable
requires a condition.
