Find strength function within the index of string waves the first winds of the substring sub is found.
Example in order to check a specific character in a string.
This is user code would find.
We will get to in order to check from index to two end of string.
This is a used car lot and fine s and two we will get three check from index a 212.
This is user could not find as it ended well we will get nine in order to check the special character
which is not found in a string not far fine find function is like that index function but differ.
In the next example this is user core.
Dot find the negative one.
This is use a car dot index D.
We will get value.
Error.
We will try our lines scoots in the bitter notebook in order to check specific character in a string.
This is user core not find I shift into who would get to in order to check from index to two end of
the string.
This is user called to find is to
three in order to check from index 8 so twelve.
This is user called Good find s from character to character.
We will get nine in order to check special character which is not found any strangely good fine.
Function is like an index function but different in next.
Example this is user code that finally will give us minus 1.
This is because we don't have these characters.
For index function this is user core not index.
D
We will get value.
Error as we explained before.
