O Write a main function which prompts the user to set a new password. The password should be read as a single token (i.e. containing no whitespace) from the standard input. The user should be prompted repeatedly, until the supplied password con- forms to the rules. For full credit, the main function must call the functions from (a) and (b), either directly or indirectly. Sample user session:

In c++language
Please only answer questions c, it’s related to question a and b
![(a) Write a function which returns true if a C-string contains a given character, false
if the character is not present. Its exact declaration should be:
bool contains_char(char cstring[], char target)
The function should contain no cout statements.
You may use strlen, but not strchr or std::string.find.
Here are some test cases:
• contains char("", ’ a') → false
• contains_char("a", 'a') → true
• contains_char("hello", 'h’) → true
• contains_char("hello", 'e') H true
• contains_char("hello", 'o') → true
• contains_char("hello", '!’) H false
(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*1loworld") true
• is-good-password("!helloworld") true](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F50dee9fd-c842-4c78-b313-0b52af8adedd%2F18d30a77-9567-4b72-973a-cb11770f7016%2Fxjup7d_processed.jpeg&w=3840&q=75)
