1
Algorithms
An array contains [9, 2, 6], to be sorted using insertion sort. Show the state of the array after each new element has been inserted into its correct position.
2
Translators and Integrated Development Environments (IDEs)
A program compiles and runs but always outputs an average that is too small. State the type of error and explain why the translator did not report it.
3
1D and 2D Array Processing: Writing and Tracing Programs
Write a loop in pseudocode that outputs every element of a 1D array named names of length 6.
4
Programming Fundamentals
Write one line of pseudocode that converts the string stored in heightInput into a real number and stores it in a variable called height.
5
Producing Robust Programs
Explain why iterative testing, carried out throughout development, tends to make errors cheaper to fix than relying only on final testing.
