THIS PAPER HAS GIVEN IN IIT DELHI , SO GO THROUGH THIS IT WILL GIVE
ROUGH IDEA;
1. typedef struct{
char *;
nodeptr next;
} * nodeptr;
what does nodeptr stand for?
2. supposing thaty each integer occupies 4 bytes and each charactrer
1 byte , what is the output of the following programme?
#include<stdio.h>
main()
{
int a[] ={ 1,2,3,4,5,6,7};
char c[] = {' a','x','h','o','k'};
printf("%d\t %d ", (&a[3]-&a[0]),(&c[3]-&c[0]));
}
ans : 3 3
3. what is the output of the program?
#include<stdio.h>
main()
{
struct s1 {int i; };
struct s2 {int i; };
struct s1 st1;
struct s2 st2;
st1.i =5;
st2 = st1;
printf(" %d " , st2.i);
}
ans: nothing (error)
expl: diff struct variables should not assigned using "=" operator.
4.what is the output of the program?
#include<stdio.h>
main()
{
int i,j;
int mat[3][3] ={1,2,3,4,5,6,7,8,9};
for (i=2;i>=0;i--)
for ( j=2;j>=0;j--)
printf("%d" , *(*(mat+j)+i));
}
ans : 9 6 3 8 5 2 7 4 1
5.
fun(n);
}
int fun( int n)
{
int i;
for(i=0;i<=n;i++)
fun(n-i);
printf(" well done");
}
howmany times is the printf statement executed for n=10?
ans: zero
expl: Befire reaching to printf statement it will goes to infinite loop.
6.what is the output of the program?
main()
{
struct emp{
char emp[];
int empno;
float sal;
};
struct emp member = { "TIGER"};
printf(" %d %f", member.empno,member.sal);
ans: error. In struct variable emp[], we have to give array size.
If array size given
ans is 0, 0.00
7. output of the program?
# define infiniteloop while(1)
main()
{
infiniteloop;
printf("DONE");
}
ans: none
expl: infiniteloop in main ends with ";" . so loop will not reach end;
and the DONE also will not print.
8. output of the program?
main()
{
int a=2, b=3;
printf(" %d ", a+++b);
}
ans:5
expl: here it evaluates as a++ + b.
9. output of the program?
#define prn(a) printf("%d",a)
#define print(a,b,c) prn(a), prn(b), prn(c)
#define max(a,b) (a<b)? b:a
main()
{
int x=1, y=2;
print(max(x++,y),x,y);
print(max(x++,y),x,y);
}
ans: 3 4 2
10. which of the following is the correct declaration for the function
main() ?
ans: main( int , char *[])
11. if ptr is defined as
int *ptr[][100];
which of the following correctly allocates memory for ptr?
ans: ptr = (int *)(malloc(100* sizeof(int)); |
