Textbook Question
Chapter 9, Problem 4E
Write a function called s to extract a portion of a character string. The function should be called as follows:
s
where S is the character string from which you are extracting the substring, S is an index number into S indicating the first character of the S, c is the number of characters to be extracted from the S string, and r is an array of characters that is to contain the extracted substring.
For example, the call
s
extracts the substring̎ (three characters starting with character number 4) from the string̎ and places the result in r.
Be certain the function inserts a null character at the end of the substring in the result array. Also, have the function check that the requested number of characters does, in fact, exist m the string. If this is not the case, have the function end the substring when it reaches the end of the source string. So, for example, a call such as
s
should just place the string “words” inside the result array, even though 20 characters were requested by the call.

Complete the check_character() function which has 2 parameters: A string, and a specified index. The function checks the character at the specified index of the string parameter, and returns a string based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The function calls below with the given arguments will return the following strings:
check_character('happy birthday', 2) returns "Character 'p' is a letter"check_character('happy birthday', 5) returns "Character ' ' is a white space"check_character('happy birthday 2 you', 15) returns "Character '2' is a digit"check_character('happy birthday!', 14) returns "Character '!' is unknown"
use python please
def check_character(word, index): # Type your code here. if __name__ == '__main__': print(check_character('happy birthday', 2)) print(check_character('happy birthday', 5)) print(check_character('happy birthday 2 you', 15))…

Question (Strings)
Write a function find_Substring() that finds a substring into a string. Pass array s1 and s2 to this function and prints if the substring is present or not.
Expected Output 1:
Enter string
This is a javascript Enter substring script
The substring is present
Expected Output 2:
Enter string
This is a javascript
Enter substring
Jscript
The substring is not present
Write a function namedisInt that hasone parm, a stringand returnsanint. The function should return true (in the C sense) if the string contains an int (all characters in the string are digits) and return false (in the C sense) otherwise. USE POINTER NOTATION INSTEAD OF ARRAY NOTATION. NO BRACKETS.

- vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage: >>> vowelIndex('hello') 1 >>> vowelIndex('string') 3 >>> vowelIndex('string') 3 >>> vowelIndex('BUY') 1 >>> vowelIndex('APPLE') 0 >>> vowelIndex('nymphly') -1 >>> vowelIndex('string')==3 True >>> vowel Index ('nymphly')==-1 Truearrow_forwardEach function deals with null terminated C-strings. You can assume that any char array passed into the functions will contain valid, null-terminated data. Your functions must have the signatures listed below. This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string. int findSubstring(char *s, char substring[])arrow_forwardBinary to String Create a function binary_to_ascii_string() that converts binary information into ASCII characters.
