Thread: how to parse this file?

I have a file as follows:

Code:

cons: chromosome06 31329000 0 T Zero coverage
cons: chromosome06 31329001 0 T Zero coverage
cons: chromosome06 31329002 0 G Zero coverage
cons: chromosome06 31329003 0 G Zero coverage
cons: chromosome06 31329004 0 A Zero coverage
cons: chromosome06 31329005 0 C Zero coverage
cons: chromosome06 31329006 0 A Zero coverage
cons: chromosome06 31329007 0 C Zero coverage
..

cons: chromosome06 31329000 0 T Zero coverage
I want to get the content whose color is blue,
but I don't know how to process it, I am a newbie who begin to learn c++
Can anyone help me?
I want to load into memory using two-dimension array:

Code:

char **chr;
chr[6][31329001] = 0;

Doesn't strtok() qualify as a standard STL string tokenizer?

No. It's part of the C standard, not the STL, and it doesn't work on STL strings.

I write a test code using strtok,but it can't work,
why?

Code:

      //#include "syslib.h"
      #include <string.h>
      #include <stdio.h>
      using namespace std;
      main()
      {
        char *s="Golden Global View";
        char *d=" ";
        char *p;
        
        //clrscr();
        
        p=strtok(s," ");
        
        while(p)
        {
          printf("%s\n",s);
          strtok(NULL,d);
        }
        
        //getchar();
        return 0;
      }

strtok is destructive, and as such can't be called on nonmodifiable/const data, which s is (it points to a string literal, which is not memory you own or can change).
