I am programming in C and am having some trouble finding the .txt file I saved after having run my program. It is likely a stupid error on my behalf. However, it is causing me quite a bit of grief at the moment. I attached my source code below
abgcchp27ex1.txt (2.01K)
I coded my structure within my header file(bookInfo.h) correct along with everything else. My dilemma is a matter of my file location and whether it actually saved.
/* This program takes the book info program from chapter 27 and writes the info to a file named bookinfo.txt. */
// First include the file with the structure definition
I have to develop an application that uses Qt, Excel and live-time file checking. My client gave me this:
I have a problem at work. I need you to develop this: I want one application with GUI (it said windows), that generates an report for each sheet (employee name) in the file, with the columns. I don't want to make the computer slower, so check the file and get the name of the employee that is altered and only change his report
How to start it. All Excel libraries I use stop working on my computer and this "File Checking" is other trouble, because if for each second I compare the size of the "old" file with "new" file, the memory will explode.
I am trying to use a combination of windows batch scripts as well a C++ program to put users data into one single .CSV file. Right now, I have a batch file that will output data from the command line into multiple .txt files. These files are mac.txt, serialnumber.txt, computermodel.txt, and computer name.txt. What I want to do, is to have users run the batch file, which will in turn run the .exe C++ file which will concatenate all their data into one file, computerinfo.csv. The file format for this file would be to have the mac address, serialnumber, computer model, and computer name all in their own column.
My main issue is that these individual files don't have the format that I would like, but based on the command prompt functions, there isn't really any good format. For example, the mac.txt file has the following format:
Physical Address Transport Name =================== ========================================================== xx-xx-xx-xx-xx-xx DeviceTcpip_{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} yy-yy-yy-yy-yy-yy Media disconnected zz-zz-zz-zz-zz-zz Media disconnected
but all I really want is xx-xx-xx-xx-xx-xx
The other files have other issues with format, but if I can figure out this one then the others should be a piece of cake.
Also, I want the output of this to all go in one row, and as other users run this file, they will go into new rows without touching the rows above.
I have a desktop application in which i want to copy files from my local computer to an online server. I have the user name and the password of the server. is there any way like
file.copy(sourcePath,destinationPath)
to copy the files where the destinationPath will be something like
Modify program 3 by saving the header file on your memory stick and remove it from the Header section of the VC++ in the Solutions window.
Code: #include<stdio.h> #define pi 3.141592654 #define A (num) * (pi) * (Radius) /* a macro defines a math equation */ float spherevolume (float); main() {
In my project , we need to create an Array of Unicode Strings . The Array will contain 5000 Strings.
I need to write those strings to a text file which can be opened or edited with NotePad.
Normal _tfopen and fwrite are not able to create notepad compatible .txt file .. I mean the file I created is not readable with Notepad though file open mode is "w+t"
I found this program in a forum and it creates 1 to t threads with each thread pointing to the next and the last thread pointing to the first thread and it allows each thread to sequentially take a turn until all threads have taken n turns. That is when the program ends.
My doubt is if we see in void *tFunc(void *arg) function, first thread locks the mutex and then wait there forever till it's turn comes.Lets say if I spwan 1000 threads and they have take 10 turns each sequentially and what if a 550th thread locks the mutex as soon as the program starts and waiting for its turn which will never happen because still (turn=1) which means it's first thread's turn and first 549 threads have to complete their 1st turn before this 550 threda's turn comes.Doesnt this result in deadlock?
I have a file that I need to read in blocks. I need to read in n lines at a time, do some processing, and then read in the next block of n lines until the file is done. I know the size of the block, but not the number of lines in the file unless I check that first. Normally I would read in like,
Code: // declarations string new_input_line, input_file; // create an input stream and open the input_file ifstream input_file_istream; input_file_istream.open( input_file.c_str() );
[Code] .....
// process through data_block
With this approach, I'm not sure how I would keep looping to read the next block until I hit the end of the file without knowing how many lines are in the input file. I could process the file to find that out, or get that number from bash and pass it it as an argument, but it seems like that shouldn't be necessary.
I could also read in and store the entire file as a vector of string and then process through it afterwords, but that would not be a very efficient use of memory.
I wrote program for Sequential matrix multiplication .But after execution for any input value( ex. 100,150,400) it shows the execution time is 0.000 msec.
#include <stdio.h> #include <math.h> #include <sys/time.h> void print_results(char *prompt, int N, float *a); int main(int argc, char *argv[])
I have an assignment to write the code for a simulated radio station holding a contest. The contest is for a "caller" (user input obviously) to guess a number from 1 to 500. The "randomly generated" numbers are already chosen and are being stored in a .txt file. The code is to search for number guessed by the caller and if they are wrong, next caller until a caller is correct. The end result is to display the winning number, the indexed location the number was found, and how many callers guessed. This is what I have...
Code: #include<iostream> #include<fstream> using namespace std; int sequenSrch(const int prizeArray[], int arrayLength, int searchedItem); int guess();
[Code] ....
I'm not sure if I am even on the right track... when I pass something into the sequenSrh(); the code compiles, asks for the number to be guessed and ends.
I am starting to learn C, its quite an easy language to learn from the basics, I hope to learn others as time goes, I wonna know how do I get the external / remote IP of a computer?
I'm looking for a way to run my console app in C# on one computer, but the actual program is ran on another computer. IE I open the file or hit "Run" in Visual Studio on computer1, the computer2 runs the program. I was looking online and found some stuff that may be applicable, but I didn't see a very clear answer.
I have a problem with a program..I wanna make a program for scan the computer screen.I mean for example there is a video which shows just 5 pictures(apple,pear,banana,strawberry,cherry pictures) but this pictures are turning nonstop in one second. and this case is continuous progress.There are 5 pictures and are chancing. Lets get my problem, I wanna make a program and when apple on the screen my keyboard will push 1,when pear on the screen my keyboard will push 2,banana is 3,strawberry is 4,cherry is 5. I have this 5 pictures which are in the video and I will introduce tham to program and I wanna compare my lib. and screen and get output.
I am writing a program in which the computer will read a txt file and encypt it. The encryption works fine, but the computer cannot read the file perfectly. If there's a newline, the scanning process stops. For example I have the following text in the txt file.
One two three four five (newline) Six seven eight
The computer will stop reading after 'five'. I assume that is because I use fgets.
I have a weird problem, my computer restarts imidiately after program writen in dev-cpp is compiled AND run. When I run any program, it lasts about 1 second, then program closes, and computer reboots. It doesn't matter whether program is writen now or earlier, my dev-cpp version is 4.9.9.2. Source code can be as simple as this:
#include <iostream> #include <conio.h> using namespace std; int main() { getch(); return 0; }
