A program contains a global 1D array Data with 100 elements of type INTEGER. The program contains a function Process() expressed in pseudocode as follows: FUNCTION Process(Number : INTEGER, Label : STRING) RETURNS STRING DECLARE Index, Count : INTEGER DECLARE ReturnValue : STRING Count ← INT(100 / Number) Index ← Data [Number] CASE OF (Index MOD 2) 0 : ReturnValue ← TO_UPPER(RIGHT(Label, Count)) 1 : ReturnValue ← "****" ENDCASE RETURN RetVal ENDFUNCTION

1. (a)Run-time errors can be generated in different ways. For example, a run-time error will be generated if a function is called with invalid parameters. The pseudocode contains three statements that could generate a run-time error. Write the three statements and explain how each could generate a run-time error. Statement 1 Explanation Statement 2 Explanation Statement 3 Explanation[3]
2. (b)One type of run-time error can cause a program to stop responding ('freezing'). Identify a particular type of programming construct that can generate this type of error and explain why it occurs. Construct Explanation[2]
3. (c)The function Process() contains a selection construct using a CASE structure. Write pseudocode using a single selection construct with the same functionality without using a CASE structure.[2]
