Write statementsto show how finding the length of a character array char [ ] differs from finding the length of a String object str.

Length of char array: sizeof(arr)

Length of a string object: myString.length()

Explanation:

The sizeof approach is generally not recommended, since this information is lost as soon as you pass the array to a function, because then it becomes a pointer to the first element.

which functions return a valid value without any arguments?

(-blank- and -blank- return a valid value without any arguments.)

1st -blank-

today

sqrt

count

2nd -blank-

now
