Let's say we have this in text.txt. I can read the file like this:

FILE* stats = fopen ("text.txt", "r");while(!feof(stats) and !ferror(stats))    {   fscanf(stats, "%s", &num);        printf("%s\t", num);    }

"num" will contain each word and number. The task is to extract all numbers from the text. Any ideas?
