for an assignment we need to create basically a program that asks the user for the result of standard six-sided die rolls (numbers from 1 to 6). The program will prompt the user with "Enter a die roll or 0 to exit " for the first entry and Next die roll? for all subsequent entries. The program will continue reading die rolls from the user until the user enters 0. At this point, the program prints two newline characters (one blank line) and finally, the bar chart showing the number of times each die roll has been entered, and then terminates.If the user enters an invalid number, the program will just ignore it, and ask for another number. Only numbers 1-6 inclusive and 0 are valid.
Example output Enter a die roll or 0 to exit 6 Next die roll? 6 Next die roll? 7 Next die roll? 4 Next die roll? 0
How is it possible to store the related data of a program C++ into an external file (like as .txt) and retrieve it?
I want to write c++ program that can contain data members " id and phone"
like as Code: class profile { private: int id,phone; public: void retriever() { cout<<"Enter your ID: "; cin>>id; cout<<"Your Phone number is "<< phone; }; }
avoiding formats in above class, purpose is to store data already in txt file with different id and phone numbers and it is to be retrieved by matching id number to txt file and viewing its related phone number.
Currently i have a system that will store user input into a txt file, and have a function that will compute the daily sales of the month(Check by system date month) and display the sales of the day and the grand total of that month.
Take for example, the system date now check that the current month is Apr. Below are my current output:
20Apr2015 $11.5 20Apr2015 $15.5 22Apr2015 $4.5 25Apr2015 $4.5 28Apr2015 $4.5 20Apr2015 $4.5 Grand Total $45
But my desired result should be as below
20Apr2015 $31.5 22Apr2015 $4.5 25Apr2015 $4.5 28Apr2015 $4.5 Grand Total $45
My issue is now a segmentation fault in my sorting algorithm. In my assignment I was suppose to implement quick and insertion sort for the file, and organised strictly by ASCII values. We were allowed to look up generic algorithms for the sorts, but we have to convert them to comparing char arrays.
I haven't started trying to configure quick sort yet, but I'll supply the generic algorithm as well. keep in mind that the first line in the file contains the number of lines in the file. I'll try not to disappear this time!
This seems like a fairly straight forward assignment. Load up a file that contains a series of int values stored in ASCII and print out the ASCII characters to the console.
The problem I am having is that I am getting the numerical value of bytes ("40" for 10 numerical values, "200" for 50 values). The numbers are generated randomly by another file, but I can control how many numbers are generated. For example, if I type in:
My program is find non printable ASCII value(1 to 32) and calculate count from a text like "hi<tab>this<space>my text.i'm using library file here.(visual studio 2012)
removeascii.h(program name) #pragma once #include<stdint.h> #include <string> using std::string; namespace ascii

I'm developing a stack using a linked list. I have to develop two friend functions to do something with the list. But I've tried to understand the friendship, without any consistent result.
Extract of code:
Code: class Element { public: int Data; Element *nextElement; Element(int Element) {Data = Element; nextElement = NULL;} ~Element() { }
[Code] ....
I have no errors, but I cannot access the private properties of the class.
The thing I would like to do is: sum the elements of the stack with a friend function.
I have heard that people should implement their class member functions in files that are different from their class declaration files. But in cases there are multiple classes that are inter-related to each other, how will you review the source code ?
I have to write a function that reads letters one at a time from a text file, such as (aBCdefG) using fgetc(). However, each character needs to be inserted into the array in ascending ASCII order, so it should come out as (BCGadef). I wanted to use an insertion sort, however, that would require me to pass the whole array. My professor wants me to sort the letters as they are read, though, and not as a whole array.Can you even do that?
I have to count the letters from a text file into an array so the first spot is the number of A's second spot number of B's and so on then take the array and sort it in decending order how could i do this without loosing track of where the numbers go so if there are more b's than a's they switch but how will i know where each letter has moved in the array after it has been sorted?
Write a program using user-defined function which is passed a string and that function should cycle the string.(Do not use any string related functions). E.g.
If the string is : Chetna then it should print as Chetna, hetnaC, etnaCh, tnaChe,naChet, aChetn
I am new to coding Here is the problem. Have a program prompt the user for a filename to open. Change every alphabetic character in the file to a capital letter. Numbers and special characters should not be changed. Print the output to the screen.
Here is my code so far but i am only returning the last line of text capitalized from the file. I am trying to get the program to display all of the three lines of text from the file capitalized. The program displays the file correctly before i try and convert everything toupper();
Code:
Code: #include <stdio.h> #include <stdlib.h> #include <conio.h> #include <ctype.h> int main() { char line[81], filename[21]; int i; FILE *inFile;
I'm reading a binary file and I want to read all of the letters, but I have noticed that it doesn't read all of the letters and I think it is because of appears as data.
I have been playing around with .txt and .dat files lately. I only manage to load the files, but I don't seem to be able to load files using a variable.
Also modifying the data after it is imported is also currently problematic. I know how to go about the process without the need to import anything, but whenever I import the data I am having trouble modifying/ editing the ".txt" or ".dat" data.
I need to create a project that create a automated backup of a file.
i will get the file from C:/Folder/file.exe and move for a other created folder, but.. in every time that user make this backup, a folder will be created with year, month and date, like: C/Folder2/2014/April/16:42/file.exe.
The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code: #include <stdio.h> void writeFile(void); void readFile(void); int main(){
I am interested in creating a file of a given size and then randomly accessing the file to populate it. Is there a way to quickly create, for instance, a 4 GByte file in C++, initially populated with garbage?
How do you create a save file for a game, that is not a separate file? Specifically I am using code::blocks and sfml 2.1 to make a game and it saves to a text file at the moment. My problem is that it is very easy to modify the text file, and it is annoying to have to copy and paste several files if you want to use a copy of the game. I have a feeling that it may be to do with resource files, but I'm not exactly sure how to get these to work or whether you can modify them dynamically.
I have some ascii characters in a char variable.ex - char buf[100]="ab*(z&";
So each of the char in that char array will have some hex value.ex- *'s hex value is '2a'.
And I have a long long int variable in which there is a 64 bit hex value.
ex- long long int k=0x0000888888888888;
Now i want to subtract the char buff's hex value in k. How to accomplish it.
That is 0x0000888888888888 - 0x000061622a287a26 = 0x000027265e600e62 (final result in a buffer or a long variable is okay)
Later i want to reverse the result as 26e006e56272.It should be stored in a variable such that i should be able to access each byte from it(ex- '72'(last 2 hex digits))
I know how to find find ASCII value of given character, but I am not getting how to find ASCII value of given string. For example I want to find ASCII value of string "HELLO",so how to do that.
