That's not a tutorial. That's a concise explanation of what the string class function
find does. If you're ever going to get anywhere in programming, you're going to have to be able to read function descriptions.

size_t find ( const string& str, size_t pos = 0 ) const;
size_t find ( const char* s, size_t pos, size_t n ) const;
size_t find ( const char* s, size_t pos = 0 ) const;
size_t find ( char c, size_t pos = 0 ) const;

This is a set or prototypes for this function. As you can see, there are four forms of this function. The first one accepts two input variables, one a
const string&
and the other a
size_t
object. The
size_t
input has a default value if you don't provide one.
The other function prototypes are also quite simple.
So now read what he function actually does.
Searches the string for the content specified in either str, s or c, and returns the position of the first occurrence in the string. |
Hey, great, that's what you need. You want to look for the word "good". Let's see how we can use this. Let's take the first form.
size_t find ( const string& str, size_t pos = 0 ) const;
This is a class function, so it will be called on an object of type string, like this:
someString.find(str, pos);
Are you following this? Here is a different reference tot he same function:
