Shivdas Kanade
good question !!!!!!!!!!!
awesome question ......good work
Very good work... but question 8 has wrong answer.
Answer of question 8 is correct. You may using different compiler. Check it in Turbo c 3.5 compiler.
Question 10 & 11 are giving error redefinition of ‘num’
with gcc compiler :-/
Nice questions........
great questions but question number 8,10,12 are incorrect
gud que's like it
in question 17 the stucture is not properly because the object which is defined is defined incoorectly
Can you pleaze explain question number 5.How does it give output 4?what is operator << doing?
nice questions .Good work
nice...
hiiiiii...this is SILKY BANKA ..i m nt getting ques no.7 and 8.
In question 5......
remember the value becomes half during every right shift(>>) and 150>>30-25
150>>5 times right shift
now ,150 becomes 75(1st time)
75 becomes 37(2nd time)
37 becomes 18(3rd time)
18 become 9 (4th time)
9 become 4 (5th time)
