String array? Program are as follows : # 10 TRAN_MAX # 5 ONE_TRAN Main () { Char **tran_list; Int Rifa LEAVES OF 13 SPECIES OF LAURACEAE initialization string array */ Tran_list = (char *) malloc (TRAN_MAX); For (i = 0 i "TRAN_MAX; i++)    { Tran_list[i] = (char *) malloc (ONE_TRAN); Strcpy (tran_list[i], "1234");    } LEAVES OF 13 SPECIES OF LAURACEAE print string array */ For (i = 0 i "TRAN_MAX; i++)    { Printf ( "%s\n tran_list[%d] =", i, tran_list[i]);     } LEAVES OF 13 SPECIES OF LAURACEAE release */ String array space For (i = 0 i "TRAN_MAX; i++)    { Free (tran_list[i]);    } Return (0); } Operation time and the results are as follows : Tran_list[0] = 1234 Tran_list[1] = 1234 Tran_list[2] = 1234 Tran_list[3] = 1234 Tran_list[4] = 1234 Tran_list[5] = 1234 Tran_list[6] = 1234 Tran_list[7] = 1234 Tran_list[8] = 1234 Tran_list[9] = 1234 But TRAN_MAX # 20, the results have problems : Tran_list[0] = Tran_list[1] = $ Tran_list[2] = H Tran_list[3] = l Tran_list[4] = 1234 Tran_list[5] = 1234 Tran_list[6] = 1234 Tran_list[7] = 1234 Tran_list[8] = 1234 Tran_list[9] = 1234 Tran_list[10] = 1234 Tran_list[11] = 1234 Tran_list[12] = 1234 Tran_list[13] = 1234 Tran_list[14] = 1234 Tran_list[15] = 1234 Tran_list[16] = 1234 Tran_list[17] = 1234 Tran_list[18] = 1234 Tran_list[19] = 1234 Why in front of distortion? Please expert guidance and be grateful! String array? Put tran_list = (char *) malloc (TRAN_MAX); It's changed Tran_list = (char *) malloc (TRAN_MAX*sizeof (char *)); That is, (char *) malloc (TRAN_MAX*4); You have no room for enough Array Pointer String array? Solve the problem, so thanks! [ Closed window ]
