Write the function findFirst(). The function has two parameters: a const char * s1 pointing to the first character in a C-style string, and a const char * s2. Return a pointer to the first appearance of s2 appearing inside s1 and nullptr (0) if s2 does not appear inside s. Here is the supporting file and please keep in mind we are working with c++ pointers and C-style strings/**CS 150 C-StringsFollow the instructions on your handout to complete the requested function.
