An examination paper has a maximum of 75 marks. One of five pass grades (A to E) is assigned, depending on the mark obtained. The lowest mark for a given grade is known as the grade boundary. A program is being written to process examination marks. The five grade boundaries are stored in a global 1D array GB of type INTEGER, for example: Index | Value | Comment ---|---|--- 1 | 65 | The minimum mark for an A grade. 2 | 57 | The minimum mark for a B grade. 3 | 43 | The minimum mark for a C grade. 4 | 35 | The minimum mark for a D grade. 5 | 27 | The minimum mark for an E grade. Any paper that achieves a mark within 2 marks of a grade boundary must be checked. Using the given table, a paper with 45 marks would need to be checked.
