Technical Wipro Latest

The test was of 1 hour 30 ques. g apti and 30 of
technical.......some
ques. of g apti were very lengthy so don,t end up in solving
them.....time was less......some 15 ques. from arithmetic......and
rest
15
logical,statement interpretation,arrangement,tense
correction......and
like
that......
i am enclosing here the 2 C questions :
1. given a square matrix which consists only of 1 and 0......find
which
rows,which cols and which diagonals consist entirely of 1,s.
2. given an array of integers find all possible combinations of
the
numbers whose sum equal to 90.....
ans : knapsack problem (in data structures - aho ullman)
Note : for them solution was not the criteria.......but the
approach
was important......the solution should be generalised and
optimized........optimization was given the top priority........
here is the techincal paper :
plz try to solve them urself by trying on comp.
1. const int MAX=10;
main()
{enum a {a,b,MAX};
print MAX;
}
2. enum object is a const which can only be assigned a value at
initialization or a variable which can be assigned any value in
the
middle of
the program?
3. void *p;
what operation cannot be performed on p?
ans : arithmetic operation unless it is properly typecasted
4. char **p="Hello";
print p,*p,**p
5. main()
{char str[]="Geneius";
print (str);
}
print(char *s)
{if(*s)
print(++s);
printf("%c",*s);
}
6. what does the function fcloseall() does ?
7. main()
{printf("Genius %d",fun(123));
}
fun(int n)
{return (printf("%d",n));
}
8. difference between definition and declaration.
9. find the error?
fun()
{int i=10;
if(i<10)
return 2.0;
else
return 3.0;
}
10. int a=9,b=5,c=3,d;
d=(b-c)<(c-a) ? a : b;
print d
11. 1+2/3*4+1=?
12. In C++, a variable can be defined wherever needed whereas not
in C
13. main()
{int i=4;
fun(i=i/4);
print i;
}
fun(int i)
{return i/2;
}
14. what is an array ?
15. printf("\" NITK %%SURAHKAL%% !\"");
16. difference between scanf and gets in case of string input
17. table t1 m rows and x cols
table t2 n rows and y cols
in t1*t2 rows? cols=?
ans. m*n ,x+y
18. symbol of realtionship between 2 entities?
19. which one cannot come in data modelling
a. customer b. student c. office d. speed
20. can a database table exist without a primary key ?
21. whether higher normal forms better than lower forms as far
redundancy is concerned ?
22. file is at which level
ans. conceptual level
23. what is a foreign key
