(b) Write a function which determines if a given C-string is a valid password, that is,
if it meets all of the following criteria:
• length between 8 and 30 characters
• contains the character *' or '!
For full credit, this function must call contains_char in its implementation. Its
exact declaration should be:
bool is_good_password(char cstring[])
The function should contain no cout statements.
Here are some test cases:
• is good_password("") → false
• is good_password("hello") → false
• is-good_password("hello!") → false
• is good password("h*lloworld") → true
• is-good-password("!helloworld") –→ true
