Section 3

1.Max value of SIGNED int

2.One questin is given, long one, to find the answer U should be femiliar with the operation as follows
int *num={10,1,5,22,90};
main()
{
int *p,*q;
int i;
p=num;
q=num+2;
i=*p++;
print the value of i, and q-p, and some other operations are there.
}
how the values will change??

3. One pointer diff is given like this:
int *(*p)(char *, char*)
asked to find the meaning.

4. char *a={"jaya","mahe","chandra","buchi"};
what is the value of sizeof(a)/sizeof(char *)
a. 4 b.bytes for char c-- d.--

5. void fn(int *a, int *b)
{
int *t;
t=a;
a=b;
b=t;
}
main()
{
int a=2;
int b=3;
fn(&a,&b);
print the values os a and b;
}
what is the output--- out put won't swap, the same values remain.

a. error at runtime
b. compilation error
c.2 3
d. 3 2

6.
#define scanf "%s is a string"
main()
{
printf(scanf,scanf);
}
what is the output.

ANS : %s is string is string

printf("%d"i);

ans is 5 only.
8. char *p="abc";

{
print("%c %c",*p,*q);
}

a. aabbcc
b. aabbcc123
c. abcabc123
d. infinate loop ( this may be correct)
9. printf("%u",-1)
what is the value?
a. -1 b. 1 c. 65336 d. --

10. #define void int
int i=300;
void main(void)
{
int i=200;
{
int i=100;
print the value of i;
}
print the value of i
}
what is the output?

may be 100 200
