Complete the check_strings_same_start(word1, word2) function which is passed two string parameters.

Specification: Read sentences from the user until * is entered. Show the number of words in each sentence that contain a stretch of non-z characters with exactly 2 vowels. A stretch starts from the start of the word or after a 'z'. A stretch terminates just before another 'z' or at the end of the word. Examples: 1. Matching words: zoo, azozooza, GONZALEZ 2. Non-matching words: ozo, azoooza The sentences contain no punctuation, the words are separated by one or more spaces, and the characters may be upper or lower case. Keep reading sentences until the user enters "*". Sample I/O: Sentence: azoooza azooza zoo azoo Matching words = 3 Sentence: GONZALEZ passes the ball to VAZQUEZ Matching words = 3 Sentence: azozototzeti Matching words = 1 Sentence: * Done

Instructions: In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString(). This preserveString() function has the following description: Return type - void Name - preserveString Parameters The string Length of the string Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function. Please Finish the code ASAP: This is my current given code: #include<stdio.h>#include<string.h> #define STR_MAX_SIZE 100 void preserveString(char*, int); int main(void) { char str[STR_MAX_SIZE]; printf("Enter string: "); fgets(str, STR_MAX_SIZE, stdin); preserveString(str,…
