C++ :: Converting Console App To Larger GUI Based App
Oct 12, 2012
We never got into any gui stuff. It was strictly console apps. That being said I have been able to create a few small apps. I would like to start to create GUI based apps but I am kind of overwhelmed at the choices. I dont know where to go from here. Since I have c++ experience I would think Visual C++ would be the choice but i have been reading a lot of forums and getting other info.
Is there another language I should look at the would allow me to convert my program quicker or easier?
The console program I already created is very very simple and want to make a gui for.
Quick break down.
Reads file
Changes file contents based on search string,
saves and closes file
and kills a windows service
exits
Only thing I want to add would be the ability to run the file from a remote site within the company LAN(not a priority though). Currently it needs to be run locally on the server.

I want to create a text-based game with C++, running on the console. I have made some other text-based console games.
Which is the most interesting text-based game to learn how to program for beginners?

I want to convert the integer into a string.
int x = 693;
char chararr[max];
In my homework, x is unknown. but don't worry, I wont ask for the full code. I just need the part where you change the int into a string/array of char.
I'm thinking in circles from where to start?

i have to create a console based application in c language that can join and split bitmap images. the requirements of the application are as follows :
1. Split Image
Enter number of parts:
Enter source image path:
Enter destination folder:
2. Join Images (all images should be of same width and height)
Enter image path:
Join more Image (y/n):
3. Exit
Take care of following things:
- Application should show number of images processed while running.
- Acceptable Image format is BMP only.
- Application should give all the validations for correct image name, type, size, path, etc.

Complete the function myitohex so that its converts 8-byte integer to string based hexadecimals.
Ex: printf("0x%s",myitohex(64,hex)); should printout "0x40" on the screen
char *myitohex(uint8_t i, char *result){
???
return result;
}
I wrote:
#include <stdio.h>
#include <stdint.h>
char *myitohex(uint8_t i, char *result){
*result = i + '0';
[Code] ....
0xp gets printed out which is wrong. I think *result = i + '0'; is wrong. What changes should i do on this row ?

How to write a simple function that will take 3 ints and find the sum of the higher 2? This is what i got so far:
int findsum(int a,int b,int c)// will find the highest int and return it to our main program {
int max,max2;// this sets our local variable max
// next we will find the larger of our first 2 variables
if( a>=b)
{ max=a;
[Code] ....
How to get the second highest number and add it to max

On compilation the following program does not give any error and when i run this program then sometimes it gives the segmentation fault. Specially with the larger values. I made sure that the values i inputted are not crossing any range of data types i used. I cannot get what is making my code to give segmentation fault error.
Code:
#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
int main()

I added this snippet of code to a larger project I use to read some numbers in from a file, but for some reason I'm getting a segmentation fault.
Code:
printf("starting main
");
FILE *cutoffs;
double cut1=0, cut2=0, cut3=0;
printf("trying to open file
The cutoffs.in file looks something like
Code: 3.475 3.875 4.025
I ran the gdb debugger, so I know it is occurring at that fscanf; however, it doesn't give any other details (to be honest I don't have much experience with debuggers :x) ..The values are being put into an array. Before I just had numbers initialized in the array by hand, but need to have 20 different runs of this code with different numbers each time...

I am trying to understand what techiques can be used to sort really huge files (larger than available memory). I did some googling and came across one technique.
1. Are there any better ways to get this done?
2. Is there some tweaking that can be done to make this itself better?
Large enough so that you get a lot of records, but small enough such that it will comfortably fit into memory
3. How do you decide on this value? Consider, memory is 4 GB and currently about 2GB is consumed, and file to sort is 10GB in size. (Consumed memory could of course change dynamically during execution - consumed more/less by other apps.)

Why the size of a process grows larger in size for lots of small memory allocations. For example, say I have this struct, which is 16 bytes (for a 32 bit build):
Code:
struct Person {
int iID;
int iAge;
char * pForeName;
char * pSurName;
};
If I allocate memory like this:
Code:
LPBYTE lpB = new BYTE[sizeof(Person) * 1000000];
Then my process grows to 16,48KB in size, which is what I expected. However if I allocate memory like this:
Code:
Person * lpPerson;
for(int i = 0; i < 1000000; ++i)
lpPerson = new Person;
Then the process grows to 78,656KB, which I don't understand.
Additionally, I was surprised to find a vector acts more similarly to the first example. This code:
Code:
Person temp = { 0 };
std::vector<Person> people;
for(int i = 0; i < 1000000; ++i)
people.push_back(temp);
Only increases the process memory to 16,892.

How can I concatenate two 2-dimensional int arrays into one larger 3-dimensional array. This question is also valid for the 3-dimensional vectors. I know the command for the one dimensional vector as:
std::vector<int> results;
results.reserve(arr1.size() + arr2.size());
results.insert(results.end(), arr1.begin(), arr1.end());
results.insert(results.end(), arr2.begin(), arr2.end());
and for the one dimensional array as:
int * result = new int[size1 + size2];
copy(arr1, arr1 + size1, result);
copy(arr2, arr2 + size2, result + size1);
But I do not know how to make a 3-dimensional array or vector.

Q. WAP to find the next palindrome number larger than the input number.
for eg:-
Input=25
Output=33
The program is giving correct output for number with all digits '9';
why is it not giving output.

#include<string>
using namespace std;
int main() {
int len,flag=1,count=0,num,ind;

I was wondering why, in C, the sizeof of a struct is larger than the the sum of all the sizeofs of it's members. It only seems to be by a few bytes, but as a bit of a perfectionist I fine this a bit annoying.

So I'm making a console rpg and after the task of making my save/load functions I began making a sha-256 checksum so the save file can't be edited. I've pretty much all of the code but when I save the game and the checksum of that save file with my save function, I go back to load it and it always goes to the statement that says the checksums do not match and when I check the chksum.dat the hash is the same every time, here is my code:
#include <iostream>
#include <conio.h>
#include <windows.h>
#include <string>
#include <stdlib.h>
#include <stdio.h>
#include <cstdlib>
#include <windows.h>
#include <fstream>
#include "sha256.h"
using namespace std;
void MaximizeWindow() {

I have 18,000 lines of code that i would like to upgrade to include a log file. I want to replace the cout with a stream or something similar so that i can easily output to the console and to a log file at the same time with minimal change to 18,000 lines of code. I'm nearly there.
I used this post heavily as a reference; [URL] .... however it is highly incomplete and this is above my knowledge so I'm struggling somewhat.
I was able to get the bulk of it working with some guess work and modification to the code from that link.
For some reason i had to comment out "mstream(void);" and "~mstream(void);"
Also how to get :
mstream& operator<< (ostream& (*pfun)(ostream&)) {
pfun(coss);
pfun(cout);
return *this;
}
to work for endl as per the previous link. Not sure if i'm even putting it in the right place. Otherwise the code works fine for streaming to both locations and such. See the code below;
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
class mstream {

I have created a game that functions correctly, however, for balancing and future changes, I would like to record results .txt document (its 1v1 btw). I already have code to determine who won and what I am looking for is some way to keep track of different match-ups for the different characters. Im looking for something like this:
loser
Winner char1 char2 char3
char1 3 2 5
char2 2 5 4
char3 8 1 2
the numbers are the amounts of wins a given character has over another character. I'm looking for code to open the .txt file and add 1 to the respective win total so I can do balance changes and such.

Any time I run my program after I make a selection from the menu the output is printed on the console screen then immediately a windows screen comes up saying project.exe has stopped working.
Below is my code, and I suspect the error has something to either
A) due with how I'm calling the method or
B) how I have the method coded.
Main
#include <iostream>
#include <fstream>
#include <string>
#include "telephone.h"
#include "tbook.h"

Just a quick newbie question: I'm doing a console application and whenever I open a .exe using system(), the console pauses and does not run the next instruction until I close this exe. For example when I do this:
...
system("mspaint.exe");
printf("Hello");
It opens ms paint and does not print the next message until Paint is closed. How do I work around this?
