I made a vector that stores each sentence from a file. However, I noticed that each vector is stored differently. For example, if the file was "hello bob. how are you. hey there."

I used 

while(getline(mFile, str, '.'))

to get each sentence and 

vecString.push_back(str + '.');

to store each each sentence in the vector. So vector[0] would hold "hello bob.", vector[1] would hold " how are you.", and vector [3] would hold " hey there.". How do I get rid of the space in starting sentence of vector[2] and vector [3]?

The Boost String Algorithms Library has trimming functions.

There are many examples of this on stackoverflow. Have a look at these.

Strip leading (i.e. left) whitespace using:

std::string s("  String with leading whitespace.");
s.erase(0, s.find_first_not_of(" \t"));

In addition to ' ' and '\t' consider also '\r', '\n', '\v', and '\f'.
