Q 1. The National college of Journalism is offering courses in three different categories of journalism, which are the print, the web and the broadcasting media.
A student is eligible to apply if he/she satisfies any one of the following conditions:
- The student is a graduate in any discipline with an aggregate percentage of 75 or above and with a record of literary skills.
- The student is a graduate in Mass Communication with an aggregate percentage of 75 or above.
The inputs are:
- Graduate in any discipline.
- Graduate in Mass Communication.
- Aggregate percentage of 75 and above.
- Record of Literary skills.
R-Denotes eligible to apply[1 indicates Yes and 0 indicates No in all cases]
Draw the truth tables for the inputs and outputs given above and write the expression with the conjunctive operator for the terms which have 1 in the result column.
Q 2. A coin is tossed
two times. A win is said to occur, if each toss result in ‘HEAD’ otherwise in
all other cases it is a loss. Using the following as:
A=1, if the first toss result in ‘HEAD’.
A=0, if the first toss result in ‘TAIL’.
B=1, if the second toss result in ‘HEAD’.
B=0, if the first toss result in ‘TAIL’.
S=1, if Win occurs.
S=0, if the win
does not occurs.
- Draw a truth table to determine all the possible values of S, depending in the values taken by A and B.
- The rule of winning in above problem is modified as follows,
A win is said to occur if at least one toss result is HEAD, otherwise a loss occurs. Construct a truth table for the revised winning rule and write the terms using conjunction operator for the true result columns(1’s).
a) The following function is a part of some class. It returns the value 1 when the number is an Armstrong number, otherwise it returns 0.
/* An armstrong number is a number which is equal to the sum of the cube of its individual digits*/
int arms(int n)
int digit=0, sum=0; int rem=n; while(?1?)
digit=?2?; sum=sum+?3?; rem=?4?;
else return 0;
i) What is the expression / value at ?1?
ii) What is the expression / value at ?2?
iii) What is the expression / value at ?3?
iv) What is the expression / value at ?4?
v) What is the expression / value at ?5?
Q 4 The following function trial() perform are a part of some class. Answer the following parts given below. Show dry run/working.
int trial(int n)
What will the function trial() return when the value of n is 6.
Q 5. The following is a part of some class. What will be the output of the function mymethod( )
when the value of counter is equal to 3? Show the dry run/ working.
void mymethod(int counter)
if(counter= =0) System.out.println(“ “);
System.out.println(“Hello “+ counter);
System.out.println(“ “+ counter);
The following function Check() is a part of some class. What will the function Check()
return when the values of both ‘m’ and ‘n’ are equal to 5? Show the dry run I working.
int Check (int m, int n)
if (n = = 1)
return – m – -;
return + + m + Check (m, – -n)
