Question 1 of 9
1. Question
1 points#include

Question 4 of 9
4. Question
1 points#include <stdio.h>
int main()
{
char s[ ]=”God”;
int i;
for(i=0;s[i];i++)
printf(“%c%c%c%c”,s[i],*(s+i),*(i+s),i[s]);
getch();
return 0;
}Correct
Explanation:
s[i], *(i+s), *(s+i), i[s] are all different ways
of expressing the same idea. Generally array name is the
base address for that array. Here s is the base address. i is the index number/displacement from the base address. So, indirecting it with * is same as s[i]. i[s] may be surprising.
But in the case of C it is same as s[i].Incorrect

Question 5 of 9
5. Question
1 points#include <stdio.h>
int main()
{
float me = 1.1;
double you = 1.1;if(me==you)
printf(“Yes”);
else
printf(“No”);
return 0;
}Correct
Explanation:
For floating point numbers (float, double, long double)
the values cannot be predicted exactly.
Depending on the number of bytes,
the precession of the value represented varies.
Float takes 4 bytes and long double takes 10 bytes.
So float stores 0.9 with less precision than long double.
Note:
Never compare or at-least be cautious when using
floating point numbers with relational operators (== , >, <, <=, >=,!= ) .Incorrect

Question 7 of 9
7. Question
1 points#include <stdio.h>
int main()
{
static int var = 5;
printf(“%d “,var–);
if(var)
main();
return 0;
}Correct
Explanation:
When static storage class is given,
it is initialized once.
The change in the value of a static variable is retained
even between the function calls.
Main is also treated like any other ordinary function,
which can be called recursively.Incorrect

Question 8 of 9
8. Question
1 points#include <stdio.h>
int main()
{
int c[ ]={2.8,3.4,4,6.7,5};
int j,*q=c;for(j=0;j<5;j++)
{
printf(” %d “,*c);
++q;
}return 0;
}Correct
Explanation:
Initially pointer c is assigned to q.
In the loop, since only q is incremented and not c ,
the value 2 will be printed 5 times.Incorrect

9. Question
1 points#include <stdio.h>
int i;
int main()
{
printf(“%d”,i);
i=20;
printf(“%d”,i);return 0;
}Correct
i when declared above main become a global variable. default value of
global variable is 0.
and inside main it is initilised as 20.
so output is 020Incorrect
