(b) provide the coordinates (x, y) of ten points, find a procedure which will output the
coordinates of all points which lie inside or on the circle with unit radius with its
center at (0, 0) (10 marks)
(c) What do you understand by the term ‘token’ in C language (4 marks)

(vii) (p*(m+k) (viii) k/*d (8 marks)
(c) If statement in c language evaluates the condition expression as actual or false
(Boolean) in absence of Boolean data kind in C language, discuss how this is
achieved. (6 marks)
6. (a) provide the syntax of three kinds of loops in C. discuss working of every loop. provide one
example for every kind of loop. (12 marks)
(b) a and b are two arrays every with 10 elements write a program to obtain array C such
that
C[0] = a[0] + b[9]
C[1] = a[1] + b[8]
: : :
C[8] = a[8] + b[1]
C[9] = a[9] + b[0]
7. (a) elaborate User described functions? provide 1 example. (8 marks)
(b) Write a program to obtain the intersection of two arrays a and b with size m and n
respectively. (12 marks)
8. (a) discuss any 4 built in string functions. provide 1 example for every.
(12 marks)
(b) If P is a pointer having address ‘2000’ what would be values for the subsequent.
P = P+2; for int * P
P = P – 1; for float * P
P = P + 10; for char * P
P = P + 1; for double * P ( four marks)
(c) What is call by value and call by reference
