Test Date : 11 July 2003
Campus Interview Conducted in Surathkal on 11th July -2003
Test was of 1 hour 30 questions. g aptitude and 30 of technical.......some
questions. of aptitude
were very lengthy so don't end up in solving them.....time was
less......some 15 questions. from
arithmetic......and rest 15 logical,statement
interpretation,arrangement,tense correction......and
like that......
Given a square matrix which consists only of 1 and 0......find which
rows,which cols and which diagonals consist entirely of 1's.
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........

const int MAX=10;
main()
{

char str[]="Geneius";
print (str);
}
print(char *s)
{
if(*s)
print(++s);
printf("%c",*s);
}
ans. suiene
what does the function fcloseall() does ?
ans. fcloseall() closes all open streams except stdin,stdout,stderr,stdprn

{
return (printf("%d",n));
}
ans. 123genius3
difference between definition and declaration. ans. definition once while
declaration more than once
find the error?
main()
{
void fun();
fun();
}
void fun()
{
int i=10;
if(i<10)
return 2.0;
return 3.0;
}
ans. no error but warning
int a=9,b=5,c=3,d;
d=(b-c)<(c-a) ? a : b;
print d
ans 5
1+2/3*4+1=? Ans. 2
In C++, a variable can be defined wherever needed whereas not in C
main()
{
int i=4;
fun(i=i/4);
print i;
}
fun(int i)
{
return i/2;
}
ans 1
what is an array ?
ans. contiguous collection of memory occupied by similar data types
printf("\"NITK %%SURAHKAL%% !\"");
ans. "NITK %SURATHKAL% !"
difference between scanf and gets in case of string input ans. scanf does
not accepts white space while gets does
