Write a C++ function called ay that makes a copy of a C-string and also adds the two characters "ay" to the end of it. Here is what it should do: Dynamically allocate memory (using new) for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character! Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string. Return a pointer to the result string. The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you like, but you are not required to. You do not need to demonstrate calling this function. Example: ay("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "Giantsay"

Write a C++ function called ay that makes a copy of a C-string and also adds the two characters "ay" to the end of it. Here is what it should do:

Dynamically allocate memory (using new) for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character!
Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string.
Return a pointer to the result string.

The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you like, but you are not required to. You do not need to demonstrate calling this function.

Example: ay("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "Giantsay"

Your function must have the following signature:

char* ay(char *str)

In C++, Write a function that receives a string of characters and return true if the string is in language, otherwise it returns false. You may use following function header (Assume a string is in language if it is read from the left side is the same as it is read from the right side. For example, a-b-d-c is not in the language, a-b-c-a-c-b-a is in language): bool isInLanguage_2(string aString) And I also, want to know if my if statement is incorrect, and if it is how is it incorrect?
In C++ how does a beginner level programmer create a function that will take a random word from a dynamic string array and hide the word for the user to guess letter by letter? If the user guesses the letter correctly, then the program will reveal only the correctly guessed letter of the world while the rest are blocked until the full word is guessed correctly. For example -> if the word is "world" then it could appear as "*****" and if the letter 'r' is guessed then it would show "****" and so on until the full word is revealed.

Create a c++ find function that finds a word or phrase within a string. This function should accept the string, and the word or phrase to look for. It should return a list of the character elements where the start of the word/phrase is found in the string. however, this list of elements must be returned as a char* type (not as a string nor individual integers). EX testString) Hello I am Hello Today I am Named John. I like to say Hello. input word string = Hello; find(String, word) //This function call should return 0, 11, 54 because H of Hello is the 0th character, 11th character, and 54th character in testString.
