Is there a reason you are using C-strings instead of std::string? Using std::string should make things much easier.

now if we use std::string then what is the logic can u help me??

Use a stringstream and the stream extraction operator>> to extract "words" from the string.

vector<string> words;
string line("This is a test string");
istringsteam ins(line);
string temp;
while(ins >> temp)
   words.push_back(temp);
