1st step to ZOHO - Technical Apti Questions - June 15th 2016
TECHNICAL APTITUDE:
1)Predict
the output:
main()
{
unsigned
int i=65000;
while(i++!=0);
printf("%d",i);
}
2)
Predict
the output:
void
main()
{
int
i;
char
a[]="\0";
if(printf("%s\n",a))
printf("Ok
here \n");
else
printf("Forget
it\n");
}
3) Predict the output:
main()
{
char
*str1="abcd";
char
str2[]="abcd";
printf("%d
%d %d",sizeof(str1),sizeof(str2),sizeof("abcd"));
}
4) Predict
the output
void
main()
{
char
a[]="12345\0";
int
i=strlen(a);
printf("here
in 3 %d\n",++i);
}
5) What
will be output if you will compile and execute the following c code?
void main(){
char c=125;
c=c+10;
printf("%d",c);
}
6)What will be output if you will compile and execute the
following c code?
void main(){
int a=2;
if(a==2){
a=~a+2<<1;
printf("%d",a);
}
else{
break;
}
}
7) What
will be output if you will compile and execute the following c code?
void main(){
int x;
for(x=1;x<=5;x++);
printf("%d",x);
}
8) Predict the output
char p[20];
char *s = "string";
int length = strlen(s);
int i;
for (i = 0; i < length;
i++)
p[i]
= s[length — i];
printf("%s",
p);
9) Predict the output
#include <stdio.h>
int main()
{
void demo();
void (*fun)();
fun
= demo;
(*fun)();
return 0;
}
void demo()
{
printf("hello");
}
10) )
Predict the output
int incr(int i)
{
static int count = 0;
count =
count + i;
return (count);
}
main()
{
int i,j;
for (i = 0; i <=4; i++)
j
= incr(i);
}
11)
Consider the following C declaration
struct {
short s [5]
union {
float y;
long z;
}u;
}
t;
|
Assume
that objects of the type short, float and long occupy 2 bytes, 4 bytes and 8
bytes, respectively. The memory requirement for variable t, ignoring alignment
considerations, is -------------
considerations, is -------------
12) )
Predict the output
#include<stdio.h>
int *check(static int, static int);
int main()
{
int *c;
c = check(10, 20);
printf("%d\n", c);
return 0;
}
int *check(static int i, static int j)
{
int *p, *q;
p = &i;
q = &j;
if(i >= 45)
return (p);
else
return (q);
}
13)
What will be output if you will compile and execute the following c code?
#include "stdio.h"
#include "string.h"
void main(){
char *str=NULL;
strcpy(str,"cquestionbank");
printf("%s",str);
}
14) Predict
the output
#include <stdio.h>
void f(char**);
int main()
{
char *argv[] = {
"ab", "cd", "ef", "gh", "ij",
"kl"
};
f(argv);
return 0;
}
void f(char **p)
{
char *t;
t
= (p += sizeof(int))[-1];
printf("%s\n",
t);
}
15) Predict
the output
#include <stdio.h>
int main(void)
{
int i;
int *ptr = (int *) malloc(5 *
sizeof(int));
for (i=0; i<5; i++)
*(ptr
+ i) = i;
printf("%d
", *ptr++);
printf("%d
", (*ptr)++);
printf("%d
", *ptr);
printf("%d
", *++ptr);
printf("%d
", ++*ptr);
}
