Remove last character from each line in a text file

Remove last character from each line in a text file

Hello,

Removing last character from each line can be done easily using the following C program. Just compile and run:

_{int main(int argc, char * argv[])}

_{

    _{FILE * InputFile;}

    _{off_t position;}

        _{int charsToDelete;}

 

    _{if ((InputFile = fopen(argv[1],"r+")) == NULL)}

    _{

            _{printf("tdes: file not found: %sn",argv[1]);}

    _}

    _else

    _{

                _{charsToDelete = 5;}

        _{fseeko(InputFile,-charsToDelete,SEEK_END);}

        _{position = ftello(InputFile);}

        _{printf("Pos: %dn",(int)position);}

        _{int i;}

        _{//for(i = 0;i < charsToDelete;i++)}

        _//{

        _{//  putc(InputFile,'b');}

        _//}

    _}

    _{fclose(InputFile);}

    _{return 0;}

_}
