How could I search a vector element with multiple strings
i.e. vector.at(i) = This is a test
How could I search that to look for the word "test" in that element?
Thanks in advance!

Use for_each and a custom lambda.
Thanks for the reply but not sure what you mean.
for_each is a standard algorithm (specified in the standard header <algorithm>) can be used to perform some action on every element of a vector. A custom lambda is one way to specify that action as being to find a particular substring.
Look up the concepts of algorithms (in all standard versions of C++) and lambdas (in C++ 11).

Why not use string::find() ?
I think that you already now, that the "vector.at(i)", will give you actually an std::string, which of course can contain a colletction of strings.

By your question, it would seem as if you know how to search through a string normally. Now searching through a string in a vector is no different.
A particularly easy option would be to just declare a const-reference to the string in the container, then it should reduce the problem to exactly what you appear to know how to do already.
Code:const std::string s = vector.at(i); // Now do your search within s.

Ntoice that now he has changed his signature.
