    Casting

    I am trying to read a line in from a text file which contains strings of characters and intergers. I read the line into a char*. I then need to parse the line. When it comes to storing the intergers as an int, I need to cast them as they have been read using a char*.

    I know casting a char* as an int which is already an int will not give me the correct value of the integer.

    So how do I store the intergers as int.

      Clear vector

      I have a structure

      struct Rulestrc
      {
      char* rulen;
      vector<char*>v6 ;
      char* resp;
      };

      I then create an array of structures - Rulestrc tp[100]. However the content of tp is constantly changing during the run of my program, therefore I need to clear the contents of vector. I do this:

      for (y=0; y<100; y++)
      {
      if (tp[y].v6.size()) // because some of the...

        Data structure/Vector

        I am trying to read a file and then store the results in a data structure. One of the members of the structure is a vector. I use the following to push back the data 'p' into the vector 'v1'.

        Assume structure called Rulestrc

        Rulestrc* tp = NULL;

        other coding

        tp -> v1.push_back(p) ;

        The code compiles but does not run. I know it has something to do with the vector but I am...

          The thing is I have two columns in my text file and I'm only interested in the second one at the moment. That is why I used sscanf() to access the second column. How can I then read in the sentences. Thanks

              Reading from text files

              Hi

              I am trying to read in one sentence at a time from a text file, perform a number of methods on it and then move to the next sentence and so on. The text file looks like this:

              rule1 sentence 1
              rule2 sentence 2
              etc

              and the code looks like this:
              Code:
              char text[256], str[256];
fstream fid2;
char filename3[]="c......";
fid2.open(filename3, ios::in);
              ...
