POLinked List, Storing in Wrong Order?
text
Body
copied!<p>I have a question about how my linked lists are being stored. The data is being inputted from a file like 0 1 2 3 4 each number represents a different line of data. The data is not important in this question however.</p> <p>I am trying to store it into my linked lists and its being stored, but It is being stored in from bottom to top, so when i Output it, it prints out in the wrong order. I am not sure if i am storing it in the wrong order, or printing it in the wrong order Please help me, Thank You!</p> <p>Code:</p> <pre><code>struct roomData { float widthFeet, widthInch; float lengthFeet, lengthInch; char roomName[100]; int roomNumberOfType; char roomType[6]; //char of room type int roomStock[100][2]; //for storing each room stock types int roomHasStock; //if the room has a stock avaliable int roomStockCount; //how many stocks the room has float area; // sq ft float rentalRate; float profitsPerRoom; float netProfit; float grossProfit; char stockLine[200]; int x; struct roomData *nextRoom; }*startRoom; </code></pre> <p>Declaring the struct linked list like this in main:</p> <pre><code>struct roomData *rooms; //Sets them to empty startRoom = NULL; </code></pre> <p>Adding data to struct with:</p> <pre><code> void addRoomData(int n, int x, struct fileInput array[300], int check) { /******************************************************************* * NAME : void addRoomData(int n, int x, struct fileInput array[300], int check) DESCRIPTION : fills up the room struct INPUTS : n, x, array, check OUTPUTS: None */ struct roomData *temp; temp=(struct roomData *)malloc(sizeof(struct roomData)); char * word3 = (char *) malloc(100) ; // used with strTok char salesName[100] = ""; word3 = strtok(array[n].input," "); //roomType strcpy(temp->roomType, word3); word3 = strtok(NULL," "); //roomNumberOfTYpe temp->roomNumberOfType = atoi(word3); word3 = strtok(NULL," "); //roomLengthFeet temp->lengthFeet = atof(word3); word3 = strtok(NULL," "); //roomLengthInches temp->lengthInch = atof(word3); word3 = strtok(NULL," "); //roomWidthFeet temp->widthFeet = atof(word3); word3 = strtok(NULL," "); //roomWidthInches temp->widthInch = atof(word3); //room area temp->area = (((temp->lengthFeet * 12) + temp->lengthInch) /12) * (((temp->widthFeet * 12) + temp->widthInch) /12); word3 = strtok(NULL," "); //rentalRate temp->rentalRate = atof(word3); word3 = strtok(NULL," "); //forSalesName while(word3 != NULL ) //fills up the name array and stores it into salesName with concatanation { strcat(salesName, word3); strcat(salesName, " "); word3 = strtok(NULL, " "); } char *ptr = (char *) malloc(100); //delets new line from string if( (ptr = strchr(salesName, '\n')) != NULL) *ptr = '\0'; char roomNumber[10]; sprintf(roomNumber, " %d", temp->roomNumberOfType); strcat(salesName, roomNumber); //adds room number to salesName string if(strcmp(temp->roomType, "S")==0) strcpy(temp->roomName, salesName);//store salesName with roomNumner if(check == 1) //for stock values in room { temp->roomHasStock = 1; n++; /* strcpy(temp->stockLine, array[n].input); printf("%s", array[n].input); int a,b = 0 ; word3 = strtok(array[n].input," "); //stockType printf("%s \n", word3); temp->roomStock[a][0] = atoi(word3); //sores stock number printf("%s \n", word3); word3 = strtok(NULL, " "); //stockCount temp->roomStock[a][1] = atoi(word3); //sores stock inventory temp->roomStockCount = 0; //for storing how many stocks in room a++; //next value in array temp->roomStockCount++; //if a stock was saved, then inventory + 1 while(word3 != NULL ) //fills up the name array and stores it into salesName with concatanation { word3 = strtok(NULL, " "); //takes each value stockItem and stockCount temp->roomStock[a][b] = atoi(word3); //stores b++; //for count if(b == 2) //if reaches after count, reset so it can store item number { a++; //next item number temp->roomStockCount++; //inventory + 1 b=0; } } a = 0; //reset values b = 0; //reset values */ }//end if if (startRoom== NULL) { startRoom=temp; startRoom->nextRoom=NULL; } else { temp->nextRoom=startRoom; startRoom=temp; } } </code></pre> <p>printing it with this:</p> <pre><code> void printRoomData(struct roomData *r) { /******************************************************************* * NAME : void printRoomData(struct roomData *r) DESCRIPTION : print room information INPUTS : struct roomData OUTPUTS: None */ r=startRoom; if(r==NULL) { return; } int y; printf("**************************************************\n"); printf("Room Information:\n\n"); while(r!=NULL) { printf("Room Type: %s\n", r->roomType); printf("Room Number: %d of Type %s\n", r->roomNumberOfType, r->roomType); printf("Room Length- Feet: %.2f Inches: %.2f\n", r->lengthFeet, r->lengthInch ); printf("Room Widh- Feet: %.2f Inches: %.2f\n", r->widthFeet, r->widthInch ); printf("Room Area: %.2f sq ft\n", r->area); printf("Room Rental Rate: $%.2f\n", r->rentalRate); printf("Gross Profit: $%.2f\n", r->grossProfit); printf("Net Profit: $%.2f\n", r->netProfit); if(strcmp(r->roomType, "S")==0) //if room is a sales room printf("Sales Room Name: %s\n", r->roomName); if(r->roomHasStock == 0) //if room has no stock printf("Stock Avaliable: No\n"); if(r->roomHasStock == 1) //if room has stock { printf("Stock Avaliable: Yes\n"); printf("Stocks: %s\n", r->stockLine); for(y=0; y<r->roomStockCount; y++) //how many stock does room have?
