    i have a text file which looks like this :
    Code:
    Flooding refers to all water that overflows a node, whether it ponds or not.  --------------------------------------------------------------------------                                                             Total   Maximum                                 Maximum   Time of Max       Flood    Ponded                        Hours       Rate    Occurrence      Volume     Depth  Node                 Flooded       CMS   days hr:min    10^6 ltr    Meters  --------------------------------------------------------------------------   1064                  0.15     0.000      0  00 00       0.000      0.35   1065                  0.25     0.078      0  00 09       0.049      0.41   1130                  0.25     0.626      0  00 00       0.106      0.90   1155                  0.24     0.098      0  00 07       0.073      0.61   1173                  0.25     0.106      0  00 15       0.022      0.76
    i want to copy the numerical columns (no text) such that the resulting file is like as such :
    PHP Code:
    [CODE]   1064                  0.15     0.000      0  00 00       0.000      0.35   1065                  0.25     0.078      0  00 09       0.049      0.41   1130                  0.25     0.626      0  00 00       0.106      0.90   1155                  0.24     0.098      0  00 07       0.073      0.61   1173                  0.25     0.106      0  00 15       0.022      0.76[/CODE
    Till now i have managed to do this code in C :
    Code:
    #include<stdio.h>#include<stdlib.h>#include<string.h>void main(){FILE *fs,*ft;int ch;int c;fs=fopen("node.txt","r");if (fs=NULL){    puts("cannot open source file");    exit(0);}ft=fopen("new_node.txt","w");do{   ch=fgetc(fs);   if (ch=EOF)   break;   else   {    if (ch>0)    fputc(ch,ft);   }     ch++;}  while(1);  fclose(fs);  fclose(ft);  return 0;}
    The problem is that nothing is coming out of it. Can anyone help in this regard and provide a working code.

    @alienxx - Welcome to the forum!

    Please repost your code and data, so there are newlines about every 70 places or so. Somehow, your editor removed them, making it very difficult to read.

    Copy the text and code as plain text, and paste them in, the same way -- plain text. The forum software makes the code have the right font, colors, etc, if you just surround it with code tags - which you have done correctly.
