I have been working a while with saving and retrieve structs, and I still have not got it to work. I get Segmentation fault sh "${SHFILE} . I have search this error, and it has something to do with memory, but what, since I am a beginner with saving and retrieving files. The project runs fine, and the error stated above outputs into my console window as text.
Here are my two structs:
struct checkbook {
char id[50];
double value[50];
};
struct fbook {

Here is how I save and retrieve my structs:
void saveCheckbook (string file, checkbook checkbook, double initial, int counter) {
string path = "C:UsersAshwinGoogle DriveC++Checkbook" + file;
fbook save;
save.counter = counter;
save.initial = initial;
save.book = checkbook;

I started with C# 2 days ago, but i have made 3 "games". Its something like Cookie Clicker, very simple and very easy.
But I have problem with saving the game. I want to save values of variables to text file when i click on button, and when i click on another button i want to values of variables load. Just simple save system. How it works and so.
I'm very new to c and c++ and am currently working on a Caesar cipher that grabs encrypted text from a txt file and decrypts it onto a new txt file. My code builds fine in CodeBlocks and when I run it, there is a new txt file created but it stays blank.

#include <cstdlib>

The process cannot access the file because it is being used by another process.
How can i edit CStdioFile to let me open the file while the program is running.

View 7 Replies View RelatedI have a program that saves all information temporarily into memory (into the array), however, I need a permanent save solution. I have the full program working correctly, formatted perfectly, but it's missing the file array to file output.
Essentially, whenever I'm presented with the menu I'll be able to add entries, search by last name, show the entire list, and exit and save. Whenever I select option 4 the program should save to a file "address_book.txt". Whenever I reload the program, it should load from "address_book.txt" and populate the array with the preexisting data.
My question is focused on how and where I should implement the file output. What I have thus far:
#include <iostream>
#include <string.h> //Required to use string compare
#include <fstream> //Eventually used to store array into file
using namespace std;

I am working on a text-based RPG game and I want to allow the player to save his progress. So I need to save several integers and a string. And my problem starts here "How can I save integers and load them?". I read the tutorial but I dont understand. I need to write a function to save game?

Here is an error while debugging that while trying to match the argument list '(std::istream, std::string).
I have an if statement that should either match a text variable that the user has entered and a another text variable that has been got from an array but they won't match even if they are the same,Im at a lost with it.

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);

Alright I wrote this code, i know there's some mistakes but how do you go about saving its output into a txt file?
My program add something in a data base, but after program is closed all data is removed.
conturiSQLDataSet.LoginsRow newUserRow = conturiSQLDataSet.Logins.NewLoginsRow();

There is a method that program can save all data?

I have this random number
List<string> ImageList = new List<string>();
ImageList.Add("Assets/Images/Image_0.jpg");
ImageList.Add("Assets/Images/Image_1.jpg");
ImageList.Add("Assets/Images/Image_2.jpg");
[Code] .....
The problem is that It generates a random number that can be the same as the last time. So I figured out, that I need to save my random number so I can use it later, as a if statement.
If saved number == r then it generates a new number.
how to save my generated number on OnNavigatedFrom method.
I have a 64-bit uint64_t number:
Code:
Primitive<uint64_t> b = 0xCCCCCCCC00000000; I need to save the first 31 (most important) bits - 7FFFFFFE.
I found this solution in the Internet:
Code:
start = (((b)>>(first)) & ((1<<(((last+1)-(first))))-1)); but in my case for this code:
Code: Primitive<uint64_t> start = (((b)>>(32)) & ((1<<(((63+1)-(32))))-1));
I get an error: left shift count >= width of type
And even if I change 63 to 62:
Code:
Primitive<uint64_t> start = (((b)>>(32)) & ((1<<(((62+1)-(32))))-1));
I get: error: integer overflow in expression

My project involves writing a c program to generate a set of 70 decimal numbers. I want to save the output (these 70 numbers) as a txt file. I tried the following:
1. prt scr of output screen and pasting it in notepad. NOT WORKING
2. going to DOS SHELL and doing the following:
c:TCBIN>output.exe>>output.txt
NOT WORKING. Text file is generated, but it does not contain output. It just says:
illegal command: output.exe
What do I do?
I'm taking a programming class and currently we're doing data structures. Today, we discussed how to save square matrices column-wise with data structures. The teacher said that after the first few steps where you declare the structure, allocate the matrix, free it and get the dimension (which mostly make sense to me I think), you have to "get" and "set" the matrix by putting in something like
Code:
void setMatrixEntry(Matrix* A, int i, int j, double Aij) {
A->entries[i+j*A->m] = Aij;
}

I am receiving packets of data from an ethernet cable. This is the line of code that is streaming in data from the ethernet cable:
size_t num_rx_samps = rx_stream->recv(&buff.front(), buff.size(), md, 3.0, enable_size_map);[code]
Here are the segments of me trying to push the packets onto a vector:
[code]
std::vector<size_t> processing_queue; //HERE IS WHERE I'M TRYING TO PUSH THE PACKETS ONTO A VECTOR
processing_queue.push_back(num_rx_samps);
[code]
I previously had my program saving to a .dat file (the commented out lines), but I need to change it to pushing values onto a vector so I can stream the data packets from the ethernet cable to be processed. However, the packets aren't being pushed onto the stack as I suspected. What do I need to change to push the data packets onto a vector? The following is the code:
[code]
#include <uhd/types/tune_request.hpp>
#include <uhd/utils/thread_priority.hpp>
#include <uhd/utils/safe_main.hpp>
#include <uhd/usrp/multi_usrp.hpp>

Why my code is not working?

This is a simple example from and old Lafore C++ book, with a few tweaks by me. The point is simple. Save object person to a *.dat file, exit the program, then start up program again, open up *.dat file, and load contents.
The first problem is the compiler is printing a bunch of Asian characters to the file (is this normal?)
The second problem is, it's not loading the object as it should, giving me a bunch of gibberish.
I have been coding a while on a 2D random terrain game. How would I go about saving the maps? I have an array for blocks, lighting, background and background lighting. The lighting is done in real-time, so exclude that.
But with two 32000x3200 arrays, I still need to store 204800000 separate numbers in a file. Oh god. How can I have this? I could write down the separate numbers, but...yeah.
If it matters, this is made in freeglut.
