Every sheet in February 1999
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st February 1999Write a loop in pseudocode that outputs every element of a 1D array named names of length 6.
- 2nd February 1999A mono sound clip has a sample rate of 4000 Hz and lasts 2 seconds. Calculate the total number of samples taken.
- 3rd February 1999State the type of program that is typically stored in ROM.
