Some sample "c" question from the paper:
1) a null statement is a null pointer a)t b)f
2)any fn written in c will return a value
a)t b)f
3) what is the o/p assuming a=3 b=4 c=5, a*=b+c;
a) 26 b)17 c) 27 d)60
4)to print a "%" char in printf string using
a) % b) %+ c) %% d) none
5) identify "c" keyword
a) volatile b) default c)auto d)none
6)does *p++ increment p?
a)y b)n
7)can c perform arithmetic on a void * pointer
8)const char *p & char *const p are same
a)t b)f
9)to read one char at a time without waiting for RETURN key use
a)gets() b)fgetc c)getch() d)cannot read
10)char str1[]="hello";
char str2[]="hello";
the conditional string test (str1==str2)
returns FALSE
a)t b)f
11) i had defined char a[6] in one source file and in another exten char *a will it work
a)t b)f
12) char strbuf[]="hello ";

13)for(loop=\'A\';loop<=\'z\';loop++)
printf("%c",loop);
above code will print
a) A and Z b)A to Z c)error d)A to z char
