Q. 10 The variables X, Y and Z are used in a program: X stores a whole number, Y
stores a decimal number and Z stores a flag that can be set to TRUE or FALSE.
(b) The function Same(A,B) returns TRUE if the value of A is the same as the value of B
when B is rounded to the nearest whole
number and FALSE otherwise. Write pseudocode statements to:
•define the function
•call the function with X and Y and store the return value in Z
