1)#include
int main()
{
int y = 1;
if (y & (y = 2))
printf("true %d\n", y);
else
printf("false %d\n", y);
}
2) #include
int main()
{
if (~0 == 1)
printf("yes\n");
else
printf("no\n");
}
3) What will be output of following c code?
void main()
{
struct bitfield
{
unsigned a:5;
unsigned c:5;
unsigned b:6;
}bit;
char *p;
struct bitfield *ptr,bit1={1,3,3};
p=&bit1;
p++;
clrscr();
printf("%d",*p);
getch();
}
4) #include
void main()
{
int a = 5, b = -7, c = 0, d;
d = ++a && ++b || ++c;
printf("\n%d%d%d%d", a, b, c, d);
}

8)Consider the following three C
functions :
[PI] int * g (void)
{
int x = 10;
return (&x);
}
[P2] int * g (void)
{
int * px;
*px = 10;
return px;
}
[P3] int *g (void)
{
int *px;
px = (int *) malloc
(sizeof(int));
*px = 10;
return px;
}
Which of the above three
functions are likely to cause problems with pointers?

Would
the following code compile successfully?
main()
{
Printf(“%c”,7[‘Sundaram’]);
}
main()
{
Printf(“%c”,7[‘Sundaram’]);
}
