Question

Give the value of each of the following expressions in the specified language. If the expression is illegal, give "illegal" as your answer. If the value of an expression is undefined, give "undefined" as your answer. (a) Ada: -2 ** 4 (b) Java: --i != j++ ? i--: + + j Assume that i is 4 and j is 3 before the expression is equated. (c) C: i-- || ++j ? j: i Assume that i is 2 and j is 5 before the expression is evaluated. (d) C: i/--i Assume that i is 2 before the expression is evaluated. (e) C++: d = (i = 4.5) + 1 Assume that i is an int variable and d is a double variable. (f) Ada: 8 rem (abs (4 - 7)) (g) Java: i = j + k Assume that i, j, and k are short variables and that j is 3 and k is 7. (h) APL: 24 30 - 6 times 3

Explanation / Answer

a)illegal

b)5 ,as --i=3 which is equal to ++j,after comparison it becomes 4 hence second expression is returned which is ++j=5

c) 5

d)1

e) 5

f) 2

g)undefined,compilation error:

error: incompatible types: possible lossy conversion from int to short    short i=j+k;                                                                                     

h) -17.2   

//please ask in case of any doubt,Thanks.
