Question 5
            (a)        Define programming language.
            (b)        Write the following mathematical expressions in BASIC notations:
                        (i)         x(w + y)2;
                        (ii)         ;
                        (iii)      p = 2 (l + b).
(c)        Write a simple BASIC program to calculate the area (A) of a rectangle with length (l) and breadth (b).
(d)       List two levels of programming language.

             The expected answers were:
            5.  (a)   Programming language is an artificial language designed to communicate instructions to  a machine, particularly the computer.                                                    
                  (b)(i)   x * (w+y)^2 or x*(w+y)**2                                   
                      (ii)                                                                            
                      (iii)   p = 2 *(l+b)                                                                                              
                    (c)                   BASIC PROGRAM TO CALCULATE AREA OF A RECTANGLE
                        10                REM “PROGRAM TO CALCULATE THE AREA OF A RECTANGLE”
                        20                INPUT “LENGTH” ; L
                        30                INPUT “BREADTH” ; B
                        40                LET A = L*B
                        50                PRINT “AREA =’’ ; A
                        60                END  
OR
                        10                REM “PROGRAM TO CALCULATE THE AREA OF A RECTANGLE”
                        20                INPUT L
                        30                INPUT B
                        40                LET A = L*B
                        50                PRINT A
                        60                END  
                        (d)     Any two programming languages                   
                                  Machine language;
                                  Low-level language/ Assembly language;
                                  High-level language.
           
 The question was on Developing Problem-Solving Skills.  The question was unpopular   with the candidates. As reported, most candidates could not correctly answer this problem-solving skills question. It was majorly attributed to inadequate tutorship.
            The performance was reported poor.

of it. The performance of candidates was reported to be average.
