Chapter 17 // Exercise 5 - Principles & Practice Using C++

 In this exercise I am using Visual Studio 2017 and the std_lib_facilities header provided by Stroustrup.

Chapter 17 // Exercise 5

Write a function, char* findx(const char* s, const char* x), that finds the first occurrence of the C-style string x in s.

I'm not entirely sure what he meant by this so I interpreted it as "finds the first occurrence of the C++-style string in the C-Style string".

Also, he did not specify not to use the standard library on this one. There is already the function strstr() to do this that takes in two const char*.

The actual definition of this function though is deep in the bowels of VS runtime string headers but it basically takes in two pointers to the start of the char arrays and then returns a pointer to the start of the occurrence. This means that if you print the pointer, it will print everything starting from that occurrence.

I mimicked this behaviour and also cast that const away (just like the standard library does).
