I have a file abc.txt which i need to read line by line and extract tokens from it.

while( getline( x, s1 ) )
string s2=s1.str()
strtok( s2, seps );					

In the code above i am taking an input stringstream from the file x submitted by the user and using it in s1. thereafter i am using a loop as many times i get to read a line. now i need to use the value of s1 which equals string of first line, in the strtok function's parameter. strtok does not accepts this. i converted s1 stringstream to s2 string. even then strtok is not accepting s2.

The error is ;

hw2.cpp:57: error: request for member 'str' in 'st', which is of non-class type 'char [1]'
hw2.cpp:66: error: cannot convert 'std::string' to 'char*' for argument '1' to 'char* strtok(char*, const char*)'
hw2.cpp:59: warning: unused variable 'cstr1'

You are flooding the forum with questions which you could easily answer yourself with a bit of basic research and some hard study. Get hold of a decent C++ book and study the language so you have at least a reasonable understanding of simple things like reading files, handling strings, etc.

I never meant to flood the forum . The thing is i have been stuck on this since over 8 hours. I just required a hint.

I have given you more than hints, I have pointed you towards answers but your understanding of C++ seems to be rather basic. Try reading beyond the first line of the answers you are given and take some of the advice. Spend some time studying classes, objects, strings, file handling etc, before posting what is essentially the same question again.
