Question

Write a C++ program to check whether a number divided by 2, [Hint: write a function to check remaider when 'n' is divided by 2]

Answer 1

I think that your question is to check whether a number can be divided by 2 or not.

To do this simply take that number and run it through a remainder operator. For example, n % 2. If n is 2 then the output will be 0 but if n is 3 then the output will be 1.

Using that logic, we can make a rough code like

if (n % 2 == 0) {
printf("n can be divided by 2);
}
else {
printf("n cannot be divided by 2);
}

you can finish this code up by assigning a value to n. Good luck
