Question

I am working on a file. I want to take each line and split after the space.
For example if line1 has: today is monday I want to have today, is, monday separatly in order to work on them

Here is my code so far:

FILE *file = fopen ( "file1", "r" );

            if ((file != NULL ))
            {
                char line [ 128 ]; 
                while( ( fgets ( line, sizeof line, file ) != NULL ))
                {
                //tokenize the line based on space

                ??

                }
how to add text at the end of the line? i mean i have **today is monday** and i want to add for example **Yupppy** at the end of today is monday line.

            fclose ( file );

            }

To tokenize a string you can use strtok()
Check the example in the link I post, just change the separator to space:

( code from the example linked )

#include <stdio.h>
#include <string.h>




int main ()
{
  char str[] ="- This, a sample string.";
  char * pch;
  printf ("Splitting string \"%s\" into tokens:\n",str);
  pch = strtok (str," ");
  while (pch != NULL)
  {
    printf ("%s\n",pch);
    pch = strtok (NULL, " ");
  }
  return 0;
}
