Please write it in C++

Important requirements for all questions:

No global variable is allowed to be declared and used. Constants are ok.

Functions cannot use cin or cout unless it is explicitly permitted. It should

make use of parameters and return value instead. cin and cout should be done

in main() or any testing functions

Multiple return statements in one function are not allowed.

The function cannot use the string class or string functions such as strlen. It

should only manipulate C-string as an array of chars with NULL at the end.

Please clearly show how you test your functions with at least the provided test

data

Write a function named "isJustZeroAndOnes" that accepts a C-string (an array of characters terminating by a NULL character). It returns true when the C-string just contains ' 0 's and/or ' 1 's only and false otherwise. In addition, it also returns two additional boolean flags: one flag to indicate the C-string contains only ' 0 's and the other to indicate that it contains only 'I's. In another words, this function will return 3 different boolean flags. For example, these are the C-strings with their expected return values: Write a function named "isJustZeroAndOnes" that accepts a C-string (an array of characters terminating by a NULL character).
