Code:
ig_cfunc.cpp:1609: error: `calc_rel_branch_degree' undeclared (first use this function)
I have deleted all of the objects and recompiled to make sure that everything is in sync. I can't see what the issue is here and I'm not sure what to do next. This code actually worked until I changed the name of the function, so the types are all correct and such. This is the format I use for all external functions ....
I have a function and i want to delete a file when the function is called and starts it's loop i have used this code but unfortunately the file is not deleted ?
Code: void evaluate(void) /*evaluate the population */{ int mem; int i; double x[NVARS+1]; char buffer[101] = {"save.txt"};
I am trying to use struct to store variables from a text file and use them in the main program. I have first tried running the program without using struct and declaring the variables within the main program and it runs fine. But after using struct, it gives no compilation error and a segmentation fault as output. Also, if the size of file/variable size is unknown can I declare variables as char string[]??
The code is as below:
Code:
#include<stdio.h> struct test { char string1[10000];
Code: #include <stdio.h> #include <string.h> #include <stdlib.h> int encrypt_data(FILE *);

I am trying encrypt the file "encrypt" when I enter it I get "Error in reading file"
I think its a problem with the fgets() and scanf()...I tried both fgets out and then scanf but I get the same error.
I look in the directory and see that when I enter a file to be encrypted a blank file with a "?" at the end is created in the directory. so I try to encrypt "encrypt" it shows error then creates "encrypt?"
I then tested it by entering a random file name that does not exist
EXAMPLE
Please enter file to be encrypted: fakefilename
Error in reading file.
I look in the directory the non existent file now is listed "fakefilename"
So on lines 36 - 39 (The commented out functions) is where I'm sure is causing this error because once I don't comment them out pretty much everywhere Flink or Rlink is used or defined I get this error.
I am getting undefined references when compiling a project, however, there in no reference to external library and I am including all source file and header in the project , beside the only reference is to standard C header files. The undefined references error I am getting is for a header file whose source file is already present in the project.
i saved it with name PIYUSHAN.cpp.after compiling above program, it shows no errors, that means it get compiled successfully. but when I try to run this program it shows Linker error :
Undefined symbol add(int,int) in module PIYUSHAN.CPP Linker error : Undefined symbol sub(int,int) in module PIYUSHAN.CPP Linker error : Undefined symbol mul(int,int) in module PIYUSHAN.CPP Linker error : Undefined symbol div(int,int) in module PIYUSHAN.CPP
If I DEFINE a global variable in two source files which belong to the same project, then there is a linker error "multiply defined symbols". But if I DEFINE a global variable in two source files which belong to the different projects, then it compiles fine. Why?
I wrote a program with a recursive() called finder. But it dose not work properly,at run time it becomes to a infinite status. How to detect the error at runtime. Here is the code.
#include<stdio.h> void finder(int x,int y); int tot;
[Code] ....
I think the error is the changing value of x after a round of for loop.

Ok so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) { switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.
i have been making code of a chessgame and now sddenly computer freezed and now there's not code in .cpp file! Although my .cpp file shows size of 16kb but when i open it . there's nothing except bank file
Here is program I have written which reads the destination, then finds it from a separate file, and reserves the information on a different file. But the reserved file has hex code information, how can I output my result to the file in normal alphabet/number/symbol characters? I've tried fputs,fprintf, and fwrite , and all give me the same result. The array c, is the one to be written to file.
void main { FILE *afile = fopen("flightrecord.txt","r"); int i=0,j=0,k=0,z=0,y=0,sum=0,seat=0,g=0; char destination[10],a[1000],c[1000],b[1000],name[100],last_name[100],c_number[15],plane[]={'P','6','2'}; printf("What is your destination?"); scanf("%s",&destination);
I am working on this project where I need a function to be called every second. At this time, I am thinking that I have to create a thread but I am clueless on how it will get called every second.
I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line); outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?
So the premise of my code is to read in a 2d array from a .txt. The array is a game board but the first two lines are what determine the size of the board. After i read it in i want it to find wherever te character "U" is, and then display the array but only showing U and whats around it. Problem is i cant get the array to print the right size and the code for displaying the U is not working either.
ifstream inputFile; int boardSizeRow; int boardSizeCol; inputFile.open("C:UsersMichaelDesktopfileboard2.txt"); inputFile >> boardSizeRow; inputFile >> boardSizeCol; inputFile.get();

I use a programming language called layout which nobody here has probably ever heard of. It was discontinued over 15 years years ago but it was a very visual & easy to use piece of software - no coding required. In fact once you name all the variables on cards (forms) from then on it's just mouse clicking & occassionaly typing a number if required. It used blackboxes in a flowchart arrangement which were pre-done code for doing just about anything. i.e opening windows, handling numbers & text, files etc. I have written many programs with it including database management, quoting software & currently use it in my business to track my jobs & do invoicing & ordering. It's a pity it wasn't updated & still around today.

Back to the problem. Being a 16 bit program it was written to run on Windows 3.1 but still works on Windows 7!! as long as it is the 32 bit version. I need to write a program that will run on 64 bit W7 without resorting to using a virtual PC solution. I have tried to find something similar that I might be able to use instead but so far nothing comes close to Layout. I just remembered today that layout can produce not only .exe programs but also various versions of C/C++ including visual c++. So I got this idea that if I could get those files I might be able to stick them into a C compiler program to re-make a "modern" exe file.
I could just do a simple sample program & send the source code to them to see if it works on a 64 bit version of Windows 7. how I can do this myself to produce a working exe file.
