I am just starting in c++ programming in Linux and currently, I have a 2d vector of characters, what function (or functions )can i use to find a series of characters in my vector? For example, I want to find 'h' 'e' 'l' 'p' within the 2d vector.

Is it a vector, or a 2D array?
I assume your array will be containing phrases, something like - [h][e][l][l][o][ ][w][o][r][l][d][\0]
-
[m][y][ ][n][a][m][e][ ][i][s][\0][ ]
-
[c][a][n][ ][y][o][u][\0][ ][ ][ ][ ]
-
[h][e][l][p][ ][m][e][?][\0][ ][ ][ ] // contains help at array[3][0]

You are going to have to be a bit more clear. Perhaps if you can give us what was given to you it would give us an idea what you are asking. Mind you we will not do your work for you, we will try and point you in the right direction, give you resources which will help and help debug your code for you.
Hope we can help.

What I have is a two 2d vector, which like a 2d array and it looks like what Ganon11 illustrated in the previous post. Let's take what was illustrated in the previous reply. Is there a predefined function in c++ (or in the STL) that could help me find 'h' 'e' 'l' 'p' in the 2d vector? the 2d vector is constructed as: - vector <vector <char> > notes;
and the elements are placed in the vector by making calls to push_back()
i hope i was able to make it clear....

Much clearer. Well, there are many ways. But the easiest one is to treat the vector as an array. So to access the 3 character in the 2 vector, you would do this:
.
Does this make sense?

You can use a set of nested for loop, like so (where size1 is the vector[x] size, and size2 is the vector[][x] size):
1) Looping from 0 to size1 (index i),
2) Looping from 0 to size2 (index j),
3) If the current char (vector[i][j]) is 'h',
4) Check if the next chars (vector[i][j + 1], vector[i][j + 2], etc. are 'e', 'l', 'p', etc. and NOT out of bounds
4)a. If they are, you have found the string
4)b. If not, keep searching
