This document contains information about variable naming rules, differences between scanf and gets functions, conditional statements, loops, and validating string input length. It discusses that variable names cannot start with numbers or consist of more than one word, and that system can be used as a variable name. When using scanf to read input, only characters up to a space will be read, while gets will read the entire input. It also contains examples of if-else conditional statements and nested if statements.

1. Pseudo code :
Declare Integer productCode, quantity, price, totalPrice, finalTotal, i
For i = 0 < tambah
Input productCode
If productCode < 0000000000 Then
Input quantity
If quantity < 0 Then
Input price
Set totalPrice = quantity * price
If tambah Then
Return 0;
Else
finalTotal = finalTotal + totalPrice[i]
End If
End If
End If
End

Flowchart :

2. a. Variable name can be started with numbers [FALSE]


b. Variable name can not consist of more than a word [TRUE]
c. We can make variable with name of : system [TRUE]
3. scanf(“%s”, temp) and gets(temp) have different functions. When using scanf(“%s”,
temp) what is read will only be read up to a space, for example if you input “Good
Morning” then what will come out is “Good”, while gets will read until the end, for
example if you input "Good Morning” then the output is “Good Morning”

6. The result of z = (x == 1) ? 5 : 7 if X is 0 → 7 , because 0 is not equal to 1.


Explanation : If the value of x is equal to 1 then it will be assigned the value 5. But in this
case X is 0 so the value is 7.

8. Nested selection occurs when the word IF appears more than once within IF statement.
9. Do while loop will execute the statement(s) at least once, then the condition is checked.
While loop checks the condition first and then executes the statement(s).
10.

11. a. Define a character array input of size 31 to allow for a maximum of 30 characters plus
the null terminator.
b. Use fgets to read the user’s input, and then we remove the newline character that fgets
might add to the end of the string.
c. Use the strlen function to calculate the length of the input string.
d. Check if the length of the input string is between 5 and 30 characters (inclusive). If it
is, we consider it valid; otherwise, it’s consideref invalid.

This code ensures that the input string length is within the specified range and provides
appropriate feedback to the user.
