In C language, a hexadecimal number is represented by writing

What's wrong?

$(x = 4 \&\& y = 5)? (a= 5); (b = 6);$

What will be the range of the printed numbers in the following program?

#include<iostrearn.h>
void main ()

{

int n $= 1$;
do
{
cout <<n<<"\t";
n++;
} while $(n\le 100)$:
cout <<endl;

}

What's wrong?

while $\left(\right(i < 10) \&\& (i > 24\left)\right)$
