I am struggling to finish up my game of War. There are a few problems I have ran in to. My shuffle function seems to work fine. I believe my problem lies within my game rules. When I run my code, the game usually plays all the way through but almost always ends in 'War'. I am struggling to get the game to restart after running once. I am not sure how to clear the list and start over.
The doubt is. I have a test_xpm function and I need to call this char array but this is so many pointers that I can't even figure out where I'm pointed to (?)
Code: int test_xpm(unsigned short xi, unsigned short yi, char *xpm[])
I tried something like read_xpm(xi, yi, *xpm[0]); but I'm guessing I need to index that array and run all those chars in order to show them.
I have a C program. Within it, I would like to embed either a file or a pre-assigned variable. I would prefer a method that is platform independent.
I am using the data type "RSA" from <openssl/rsa.h>. I have a key file in PEM format, but I would like to embed an RSA object in the program instead. I tried creating a char array and then casting the pointer, but that caused some sort of illegal casting issue. I tried using memcpy but I haven't been able to get it working that way. What is the best way of going about this? Is it possible to read a file directly from a memory buffer?
I am working on an OOP assignment (text handler) which part of its description is:
Some lines of text as a story which the delimiter between each story is %%%%%
Each text loaded should only occupy the space needed for the text to fit.
It's required to use dynamic variables of type char*. To be more detailed, the text-handler must contain a vector of such char-pointers (i.e. c-strings), and the parameter in the constructor indicates how many pointers (c-strings) to be contained in the vector. Each loaded text will be represented by a number, so that the first text in the file gets number 0 and the next one gets number 1 ... etc. When you want to access a text, you request the text with a certain number, and then get a pointer in return that may be used to output the text on the screen.
My problem is first to allocate a dynamic memory like char** without defining the number of array elements (Each text loaded should only occupy the space needed for the text to fit. )and then store each story from text file (comprise of a few lines of text) into that dynamically located memory(char **)to be able to do some operation on it later.
General Purpose: Delete all "white spaces" in text file, until the read-in char is _not_ a whitespace (mark as start of text file).
Problem: Cannot seem to shift char's over properly. (I think my problem is the inner loop - however other code may lead to this problem - I do not know)
Code:
#include <fstream> #include <iostream> using namespace std;
bool trimWhiteSpace(fstream &file, char * charMemoryBlock) { if (!file.is_open()) {
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 writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.
I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?
I want to sort the lines based on the FIRST value.
My text file is in the correct folder and the name of my text file is the same as the code. I dont get no errors i dont see why i cant get my text to be read.
my code.
#include "stdafx.h" #include <iostream> #include <string> #include <fstream> using namespace std; void main(); int menu(); double currentBalance(double balance);
I'm a beginner at programming and I'm not sure how to read in information from a text file. What I want to do is take a text file which contains around 20 rows and 3 columns of numbers, and put these into an array which can then be used for performing calculations. How do I do this? Would I need to declare the size of the array beforehand? When accessing my file, do I include the full address?
The relevant part is lines 29-33:
Code: #include <stdio.h> #include <stdlib.h> #include <math.h> /* this is a simpllified code using BEM equations */ main()
how to read and display the content of a text file in my console application using C++. The file contains 25 lines and 3 columns. The first column is "Rank" (numerical values from 1 to 25) the second column is "Name" (25 teams name) and the third column "value" has the amount of point each team is worth. Looking for code for reading and displaying all this information ....
I am making a script to read the latest from a text file. It picks up the line by numbytes in fseek, but the data line may vary and numbytes not be accurate, how can I fix this?
And another problem is that the line has, date, time, value, separated by space, how to read that line and put these 3 information in variable?
#include <stdio.h> #include <conio.h> int main() { FILE *arq; char Line[100]; char *result; int tam, i; // Opens a file for READING TEXT arq = fopen("temp.txt", "rt");
I'm trying to make a program that will read in names and grades from a text file and print them in the console. However whenever I try to use the OpenFile.get function I get an error saying that there is "no instance of overloaded function"
getting this error resolved before I can.
my code so far (I know it's missing a lot, but that's not what I'm worried about right now.)
How can I read text from a webpage asynchronously,from within C++. After you first connect to the internet using usual means, you enter the string
e.g. "[URL] ...." and the C++ program reads the information: "<title>BBC Website</title><body>This is the BBC website...." from the internet.
Here I want to connect to website every 60 minutes and fetch only first 100 lines of the run.txt file as mentioned above. How can I do this using C++ and asynchronous winsock ???
Code: #define WIN_OS #define _DEBUG_PRINT(X) /* X */
I have been given an assignment that has to do with permutations. I am suppose to read a text file that contains the permutation rules and the text to be "permutated", and then output the rules and the new text into an output file.
So far, I've gotten this:
Code: # include <stdio.h> void printArray(FILE* file, char* array, int maxSize) { int i; for (i = 0; i<maxSize; i++) fprintf(file, "%c", *(array + i));
[Code] ....
Here is what the input file looks like:
Code: 0 1 2 3 4 5 6 7 8 9 4 5 6 0 9 7 8 1 2 3
Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
Here is what the output file is suppose to look like:
Code: 0 1 2 3 4 5 6 7 8 9 4 5 6 0 9 7 8 1 2 3

The first two lines are the permutation rules. Currently I have figured out how to read the file into an array and then print it back out into a text.
What I want to do is figure out how to read only the first two line of the input file and store that as a permutation rules, and then continue reading the rest of the input file and store that separately as the text to be "permutated". And then eventually figure out how to apply the permutation to the text.
How to create text file in C programming. And after some changing in that text file off the running code of C, I want to read that modified text file back in C running code. e.g
Created file may have number 1, after changing this value to 2 let say, than I want to read that 2 value which is in text file.
In a program, I have a text file (called MyDictionary.txt) which has thousands of words in alphabetical order. I need to make a C program that reads in this text file and then makes an array called char Words[# of total words in the text file][length of longest word].
i have prepared a code the read from txt file with values such integers and strings. but the code i have prepared reads only 1 line. how can i make the code to read multiple records from txt file.
I'm making a Jeopardy game and when I read text from a file into arrays to set the categories, questions and answers a couple of the strings are not terminating and they are printing that junk box thing at the end.
When I use the debugger and print the problem strings they are showing up as "Thanksgiving21" or "Calvin Klein21" but all the other strings aren't having that problem.
Then for example I will change "line[strlen(line)-1] = '';" to "line[strlen(line)] = '';" and other strings will have that problem but not those stated ones. I'm using line[strlen(line) - 1] = '' to get rid of the newline fgets appends on the end of the strings.
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 the following code. Everything compiles but when it runs the sums are not correct. I need to calculate the sums for all the odd integers, the even integers, and all the integers.
my infile was provided with the following integers. I am not supposed to assume the infile has 20 integers.
Also, I wanted to the average to calculate with two decimal place precision and that is also incorrect??? setprecision(2) I thought would work???
