1. 1.
ans: (a)
reason:
you cannot declare structure as unsized array.
2.
ans: (b)
reason:
The return st.. returns x value first as it is and then
decrements its value.
Its post decrement.
3.
ans: (e)
reason:
%p represents the pointer format specifier. It prints the
value in
hexa decimal upto four digits
4.
ans: (b)
5.
ans: (b)
reason:
The values in the if st.. () is said to be in the stack. So
the last element
in the stack is taken as check value(zero/non-zero). Here TRUE
is -1 i.e.
success stateand x+y is printed.

reason:
;;; doesnot matter. This indicates only an empty statement.
The o/p will be 3,1.
13.
ans: (b)
14.
ans: (d)
reason:
The puts prints and places the cursor in the next line,
whereas
the printf prints and places the cursor in the same line.
15.
ans: (c)
reason:
You need to put '=' sign at show. ie the correct st.. is
end=(char*)(show=(char*)strcpy(start,"MISPIS,"));
or else expression error.
3. 16.
ans: (e)
reason:
The _fastcall keyword is reserved for
programming under Windows and OS/2.
17.
ans: (a)
reason:
The strcmp returns 0 if zone==target, If 0 the ?: assigns fail
st.. i.e. 0.
This is false value for IF st.. and hence else part is
executed.
18.
ans: (c)
reason:
t1 is an array. So you need to specify the subscript value
while
you assign any element to it.
char *t1; t1="craft" is correct since *t1 is a pointer and it
points
to the starting addr.. of the craft.

33.
ans: (c)
reason: odd no.. AND with 1 gives TRUE value always.
5. 34.
ans:
(b)
reason:
if we mention the string as two dimentional(for more than
one dim)
array with in printf statement,then we should give
'&'symbol
35.
ans: (b)
reason:
res=0+1/5;
res=1/5+1/4;
res=1/5+1/4+1/3;
....
res=1/5+1/4+1/3+1/2+1/1;
At last time
res=1/5+1/4+1/3+1/2+1/1+1/0;

zero divide occur
36.
ans: (b)
reason:
'%c' mainly used for print one charactor
We can't specify formate output within '%c'
37.
ans: (b)
reason:
can not modify constant value .
It is a fixed value for entire program.
38.
ans: (b)
reason:
'argc' holds number of arguments.
argc consist always value 1 becase file name is one of the
input .
therefore 1<1 gives false whereas 1==1 gives true.
6. 39.
ans: (a)
reason:
% followed by non-format specifier is printed as such
with % symbol
40.
ans : (b)
reason: if no format specifier is given immediately after the
first appearance of % then the characters after the % are
printed as such
41.
ans: (d)
reason:
the scanf must have &x,&y for %d format specifiers.
42.
ans: (a)
reason:
In if statement, x=6 is assigned and not checked.

ans: (d)
reason: t is a pointer and memory allocation is not needed for
that.
53.
ans: (a)
reason: Each 0 bit in the operand is set to 1, and each 1 bit
in the operand is set to 0 if we use ~
54.
ans: (c)
8. reason: int x:8 will get only first 8 bits assigned to it ie.,
1 byte of size
int x:9 will get only first 9 bits assigned to it ie., 2 byte
