PE09 - C-String Functions Write the following function without using the C++ string class or any functions in the standard library, including strlen(). You may use pointers, pointer arithmetic or array notation. Write the function findFirstof(). • The function has two parameters (stri, str2), both pointers to the first character in a C-style string. • You should be able to use literals for each argument. • The function searches through stri, trying to find a match for the first occurance of the C-string pointed to by str2. Return the index inside strl where str2 occurs. • Note that if str2 does not appear in str1, then return - 1. Call the function like this: cout << findFirstOf("eieioh", "eio"); // prints 2 (the index of the second e) cout << findFirstOf("aaaiii", "aia"); // prints -1 (aia not inside aaaiii) In both cases the function returns the index of the first occurrence of str2 inside stri.
