im working on mine first 2d game and im practicing a lot, how to input my inventory for character ( for items, and others ) So, i just want to let u know that i have :
So, i want to put this in my shop and if i buy it i want to appear in my inventory, or sell sell trought my inventory.Also i have one define
#define WEAPONBEGIN_WOODENSTICK (1)
Which will go instant ( when u create character ) to inventory. And:If i have 1, 2, 3, 4, 5, 6, 7, 8, 9 slots ( example ) and i sell item which was on 3rd slot, what will happen with others ? will they just go back for one slot or ?
I wanted to check whether the input is a character or not, if a character is given then the output suppose to be "ok", but the output is always "oppppssss", where is the problem here?
What I am doing is using fgetc to take a char input from the user, and then directly after that calling a function which will clear the buffer and remove the character. But for some odd reason all my inputs are being assigned before taking the char input by the user. Here is my code for the relative problem:
Code: char playAgain; Code: playAgain = fgetc(stdin); readRestOfLine(); Code: void readRestOfLine(void) { int ch; /* remove all characters from the buffer */ while(ch = getc(stdin), ch!=' ' && ch!=EOF) ; /* clear the error status of the input pointer */ clearerr(stdin); }
And en example through terminal of the issue, with print statements debugging the value of play Again:
So in both instances here I have entered 'y', one returning it as ASCII 10 which is ' ' and ASCII 121 which is 'y'.
Code: #include <stdio.h> int main(void) { char c; int i=1; while (scanf("%c", &c)==1) printf("loop sequence %i: %c(%i)
[Code] ......
Done it seems a "carriage return" serves two purposes here, one is to signal the program to read in the character typed in before the "carriage return", another serves as a second character typed, how can i do this cleanly, that is without having to use a "carriage return" as the second character to signal "I've typed in the first character already".
I am having problems printing "->" on the beginning of each line, im trying to do it as a loop and ending it when the user types "q". also i would like to know how to ignore text from the user when the input begings with a specific character. heres what ive done so far, and not currrently working as expected.
Code: #include <stdio.h> int main (void) { char prompt; printf("~~~ FRACTION CALCULATOR ~~~
I want to compare the part of the character array with the scanned input. I've initialized the character array (colourCompare).
What I want to do is, if the input colour matches up with one of the elements in the colourCompare array, it will then read the next value(I did not include "read the next value part"). If the input does not match up, then it goes back to the scanning part.
I'm very new to c programming and I have some background in C# and java. I am supposed to read a string from input then determine in that string, which character is the largest, i.e. I think b>e and e>z, e.t.c. If the string is empty I should return ' '.
I haven't done any programming in C before and I don't know how to handle strings and characters in C.
Question simple like that: Let user enter some words from keyboard, one word per line until a '.' (period) entered then print out result, for example:
Code: Enter a word: word1 Enter a word: word2 Enter a word: . You have entered 2 word(s): word1 word2
Problem is I don't know how to declare the array of character at the beginning since I don't know neither how many word user may enter nor how many letter of each word. So I go ahead and declared like this: char word[20][50] but I know it is not best way.
Code:
int main () { char word[20][50]; //array has maximum 20 words, each word maximum 50 character int i=0, number_of_word; do { printf ("Enter a word: ");
I'm new in programming, and trying to write a code in C. The requirement is following - to write a text, and to find frequency of 1 chosen character in it. The main thing is that program should check user input (for example, I want to check if user entered "char" --> then correct, or if entered "int" --> not correct). But the program still doesn't check. So I have:
Code: #include <stdio.h> int main(){ char c[1000], ch; char i, count=0; printf("Enter a text: "); gets(c);
So I'm writing an RPG and I'm in need of an inventory system. Of course as an relatively old member of the forum I know best than just come here and ask so I've already researched quite a bit and I've formulated this idea.
I've kind of conceptualized it like so: I'll have some sort of STL container of a unique_ptr of my base item class. There will be derived item classes. Taking advantage of polymorphism I can then call the new Derivedclass when inserting it in the STL container.
My questions are: What STL container should be used for the inventory(fixed sized)?
I am making a text based rpg for school and im having troubles with it. Ineed to add an inventory into my game and im not to sure as to where or how.. this is what i got for player
#ifndef PLAYER_H #define PLAYER_H //console Util.h includes <iostream> , <string> and <window.h> and defines //the NOMINMAX macro. As a result of including ConsoleUtil.h, PLayer will // also knaow about thoes objects. #include "ConsoleUtil.h"
You are requested to create an inventory control application for a drink stall (give a name to the stall). The application is used to show the list of drinks the stall sells, how many of each item on‐hand and the cost of each item. The records are to be saved and retrieved to/from a binary file called “drinks.txt”. For each drink in the stall, your program is to keep the information as a Record Structure called DrinkRecord. The structure should at least consist of the following:
(1) Item Number (2) Item Name (3) Quantity (4) Unit Price
Your application should have the following features: (a) Display a drink information (b) Add a new drink information (c) Update a new drink information (d) Delete a drink information (e) Display all drink information
Everything works fine with minor issues, but I'm having trouble with the editing function. I need to be able to search for a specific drink then be able to edit its contents and print the new contents to the file. I have not created a structure yet. I will do that as soon as possible.
I made two dimensional array to represent my (game) inventory. Slot is empty if its value is 0 and 1 if not.
Now i need to find if i can put new item in my inventory that can take up 4x2 slots. I tried this but it doesn't work as i expected:
#include <iostream> int main() { const int inventorySlotRows = 5; const int inventorySlotColumns = 5; int arr[inventorySlotRows][inventorySlotColumns] =
I am having some trouble creating a listbox in visual studio. I declared an array, set initial values, and now I would like to be able to update those values. It is a pizza inventory app, so I need to update the initial values once the user has added inventory. This is the code I have for the "Update Inventory" button:
// read in value and convert to double double dblInput = Convert.ToDouble(txtInput.Text); // loop through ingredients and add inventory to selected ingredient for (int i = 0; i < dblInventory.Length; i++) { // is item at i checked for update? if(lstInventory.GetItemCheckState(i) == CheckState.Checked)
You are required to write a program for a Used Car Dealer company. In the system you need to maintain the cars’ inventory and details. Each car in the company contains the following details:
• Car Registration Number • Car Make or Brand • Car Model • Car Colour (eg. Silver, Black , Red) • Year of manufacturing (The year the car was manufacture) • Engine Capacity (in cc) • Transmission (manual or automatic) • Cost of the car (SGD)
The Car Registration Number is in the format of AAA1234 or AA1234A or A1234A which is accordance to the Malaysia car registration format. The A alphabet is in accordance to the registration number for respective in Singapore. (eg. AEW9829 or W1212Y or MCD1177). Note the A and the 1234 total count in the registration number can be less than 3 like AT9829 or BHY280. The Car Make is for the identifying the manufacturer of the car like Honda, Toyota, Proton..etc. The Car Model is to represent the Manufacturers’ respective model like Honda City, Honda Civic, Honda Accord, Toyota Vios, Toyota Camry … etc.
You are required to create menu and operations for:
1) Create a new Car account 2) Edit existing Car account details 3) Remove a car account from the system 4) Search for cars in the system (based on Car Make, Model, Year of manufacturing or Price) 5) Check total inventory in the system
Write a constructor that initializes a new inventory object with the values passed as arguments, but which also includes a reasonable default value for each parameter.
Double values are stored in text file. 23.5 36.8 34.2 ... My teacher told me to read them character by character and then make words, like i have to read "2" "3" "." "5" and now have to make it or treat it as word and then using atoi(). I have to convert it into double. but i dont know how to do this....
I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.
