    Unix "system " command

    Hello ,

    i want to use system commnad in my code to delete files in specified
    manner.
    but this way i am not able to delete files.
    Can somebody answer .



    i tried with this as following , but not working :(
    string omcid;
    string netype ;
    string nename ;

    //some stuff to get values inside these string variables

    cout<<"omcid"<< omcid<<endl; // here i printed the value it
    iscoming correct
    cout<<"netype"< <netype<<endl ;// here also
    cout<<"nename"< <nename<<endl ; // here also
    system( ("rm -f /path/" + omcid + '_' + netype + '_' + nename
    +"_*_trans.csv" ).c_str() ) ;

    thanks

              Your subject header and this sentence are both incorrect. system() is a
              C function, not a command, and certainly not a "Unix command".
              but this way i am not able to delete files.
              Use the C remove function. Surely this is in any elementary C textbook.

              #include <stdio.h>
              int remove(const char *filename); /* returns 0 for success, nonzero
              otherwise */

              If you don't have a standard C compiler, you could try the unix system
              function unlink(). If you do that, remember that it is non-standard,
              making your program not portable and making any enquiries about it
              off-topic here.

              You also need to find out what language you are using.
              Lines like
              string omcid;
              contain an undefined identifier 'string' in C, unless you have defined
              it somewhere. If you have, show it to us; don't make us guess what it
              means,

              and things like
              cout<<"omcid"<< omcid<<endl; // here i printed the value it
              iscoming correct
              have a number of problems. 'cout' and 'endl' are undefined in C, left
              shifting by a string constant has no meaning, and the '//' style comment
              has, as you can see, resulted in a broken line with the nonsensical line
              of code 'incoming correct' as a result.

              It appears that you have no idea what language you are using, or what
              functionality is available in it.
