Wilco Paper
SECTION A: APPITUDE TEST 20 BITS
SECTION B: C BITS 20 BITS
SECTION C: 1 QUESTION (NOT A BIT)
IT IS LONG ANSWER
THE QUESTION IS:FIND THE NEXT PERMUTATION IN LEXICOGRAPHIC
ORDER FROM THE GIVEN PERMUTATION
NOTE: MAXIMUM QUESTIONS ARE FROM OLD QUESTION PAPERS
SECTION A:
1. THERE WERE 750 PEOPLE WHEN THE FIRST SONG WAS SUNG. AFTER EACHSONG 50 PEOPLE ARE LEAVING THE HALL. HOWMANY SONGS ARE SUNG TO MAKETHEM ZERO?
ANS:16
SECTION B:
1. typedef struct
{
char *;
nodeptr next;
}
* nodeptr;
what does nodeptr stand for?
ans:
2. 2 oranges,3 bananas and 4 apples cost Rs.15 . 3 ornages 2 bananas1 apple costs Rs 10. what is the cost of 3 oranges, 3 bananas and3 apples ANs Rs 15.
3. int *x[](); means
Ans:expl: Elments of an array can't be functions.
4. struct list
{
int x;
struct list *next;
}
*head;
the struct head.
x =100
Ans: above is correct / wrongexpl: Before using the ptr type struct variable we have to give memoryto that .And also when ever the struct variable is ptr then we access themembersby "->" operator.
5.o/p=?
int i;
i=1;
i=i+2*i++;
printf(%d,i);
ans: 4
6. FILE *fp1,*fp2;
fp1=fopen("one","w")
fp2=fopen("one","w")
fputc('A',fp1)
fputc('B',fp2)
fclose(fp1)
fclose(fp2)
}
a.error
b.
c.
d.
ans: no error. But It will over writes on same file.
7.#include<malloc.h>
char *f()
{
char *s=malloc(8);
strcpy(s,"goodbye")
}
main()
{
char *f();
printf("%c",*f()='A');
o/p=?
8) #define MAN(x,y) (x)>(y)?(x):(y)
{
int i=10;
j=5;k=0;
k= MAX(i++,++j)
printf(%d %d %d %d,i,j,k)
}
ans:10 5 0
9)
a=10;
b=5;
c=3;
d=3;
if(a<b)&&(c=d++)
printf(%d %d %d %d a,b,c,d)
else
printf("%d %d %d %d a,b,c,d);
ans:
: .............................................
10. what is o/p
#include<stdarg.h>
show(int t,va_list ptr1)
{
int a,x,i;
a=va_arg(ptr1,int)
printf("\n %d",a)
}
display(char)
{
int x;
listptr;
va_star(otr,s);
n=va_arg(ptr,int);
show(x,ptr);
}
main()
{
display("hello",4,12,13,14,44);
}
a) 13
b) 12
c) 44
d) 14
.............................................
11.main()
{
printf("hello");
fork();
}
ans:
12.main()
{
int i = 10;
printf(" %d %d %d \n", ++i, i++, ++i);
}
ans:
13.#include<stdio.h>
main()
{
int *p, *c, i;
i = 5;
p = (int*) (malloc(sizeof(i)));
printf("\n%d",*p);
*p = 10;
printf("\n%d %d",i,*p);
c = (int*) calloc(2);
printf("\n%d\n",*c);
}
ans:
14.#define MAX(x,y) (x) >(y)?(x):(y)
main()
{
int i=10,j=5,k=0;
k= MAX(i++,++j);
printf("%d..%d..%d",i,j,k);
}
ans:
15.#include <stdio.h>
main()
{
enum _tag
{
left=10, right, front=100, back
};
printf("left is %d, right is %d, front is %d, back is %d",left,right,front,back);
}
ans:
16.main()
{
int a=10,b=20;
a>=5?b=100:b=200;
printf("%d\n",b);
}
ans:
17.#define PRINT(int)
printf("int = %d ",int)
main()
{
int x,y,z;
x=03;
y=02;
z=01;
PRINT(x^x);
z<<=3;
PRINT(x);
y>>=3;
PRINT(y);
}
ans:
18.#include<stdio.h>
main()
{
char s[] = "Bouquets and Brickbats";
printf("\n%c, ",*(&s[2]));
printf("%s, ",s+5);
printf("\n%s",s);
printf("\n%c",*(s+2));
}
ans:
19.main()
{
struct s1
{
char *str;struct s1 *ptr;
};
static struct s1 arr[] =
{
{"Hyderabad",arr+1},
{"Bangalore",arr+2},
{"Delhi",arr}};
struct s1 *p[3];
int i;
for(i=0;i<=2;i++)p[i] = arr[i].ptr;
printf("%s\n",(*p)->str);
printf("%s\n",(++*p)->str);
printf("%s\n",((*p)++)->str);
}
ans:
20.main()
{
char *p = "hello world!";p[0] = 'H';
printf("%s",p);
}
