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.

ans: (d)
reason:
The puts prints and places the cursor in the next line, whereas
the printf prints and places the cursor in the nextline.
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.
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.

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.
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)

the scanf must have &x,&y for %d format specifiers.
