Question

I would like to push the below data into a vector using the below code.But my code works only for integers.How can I do this for the below data? Thank you.

My data:

    M,0.455,0.365,0.095,0.514,0.2245,0.101,0.15,15
    M,0.35,0.265,0.09,0.2255,0.0995,0.0485,0.07,7
    F,0.53,0.42,0.135,0.677,0.2565,0.1415,0.21,9
    M,0.44,0.365,0.125,0.516,0.2155,0.114,0.155,10
    I,0.33,0.255,0.08,0.205,0.0895,0.0395,0.055,7
    I,0.425,0.3,0.095,0.3515,0.141,0.0775,0.12,8
    F,0.53,0.415,0.15,0.7775,0.237,0.1415,0.33,20
    F,0.545,0.425,0.125,0.768,0.294,0.1495,0.26,16
    M,0.475,0.37,0.125,0.5095,0.2165,0.1125,0.165,9
    F,0.55,0.44,0.15,0.8945,0.3145,0.151,0.32,19

My code:

      fp = fopen(argv[1], "r"); //Opening the input file in read mode.
      if(!fp)
      {
          printf("open data source file failed!\n");
          goto MAINEXIT;
      }

      int ivalue;
      //extract data from files
      while(fscanf(fp,"%d,",&ivalue)!=EOF)
      {
          printf("Counter-%d\n",counter++);
          srcdata.push_back(ivalue); //Pushing value by value into the vector with "," delimiter.
      }

      if(fp)
      fclose(fp);

%d is for integers. Change it to %lf for double, and change other parts accordingly, for example, change ivalue to double.

According to your comment in the question, I think you might need something like

while(fscanf(fp,"%s", str)!=EOF)
{
    char* pch = strtok(str, ",");
    pch = strtok(NULL, ","); // skip first
    while (pch != NULL)
    {
        double d = atof(pch);
        printf("Counter-%d\n",counter++);
        srcdata.push_back(d);
        pch = strtok (NULL, ",");
    }
}
