I am in the middle of rewriting this program for at least the 4 time. and I have modified the file how I (humanly) think I should to this. I have had issues in the past, doing it this way. (still working on the other parts of the program so I cannot be too specific right now, but I know my results were unexpected ) So my question is does the function that I modified look correct for what I am trying to do? Am I off by one? I guess I am struggling with understanding how the original function is working. (step by step systematically.) hence my confusion about my modified function.
The first row has two values - number of nodes (24) and number of links (76). Then it has all the link details (76 rows of data). I want to read this data. I have written out the following function:
First the structure definitions:
typedef struct { int arcno; int tail; int head; } arc_data; typedef struct { int forwardStarPoint; int reverseStarPoint;
[Code] .....
The code is able to read the first line of data (i.e. it displays the numNodes and numArcs as 24 and 76). But then I get a lot of errors like this one
I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
Is this the right codes for deleting a recoed on the text file.
void dlte(){ string line, recorddate; cout << "Please Enter the date of record you want to delete: "; cin >> recorddate; ifstream myfile; ofstream temp; myfile.open("herald.txt");
I have to ask the user if they want to delete any records. The user can enter -1 to finish deleting records. I have to write the remaining records in an output file. So, i have this, but
1) it doesn't let me enter more than 1 id, and 2) it doesn't output anything to my output.txt.

My size of binary file is 1920 KB and my struct size is 124 kb. now to find number of records in file I divided 1920/124 and it gives me 15.4.... do I add 1 to 15.4 and make it 16 or do i take it as 15?
i have this program that i am undertaking.....this project needs to store customer details, edit them and delete them...now i am facing the problem of deriving a code to edit those details...
MY CODE
HTML Code: #include <fstream> #include <iostream> #include <string> using namespace std; int main () { int choice [1]; string name;
The program will prompt the user to enter a every student's first and last name, major ( of 4 choices CMPS MATH PHYSICS or EECE ), and grade. it's agreed that the professor will enter the name NoMore to stop the entry.
the program willl then store the info in a txt file. after closing the input file, the program will open it again read the records one at a time until end of file, and do some statistics including: highest grade, average grade, and highest average by major.
I have faced a strange problem in File Save Routine. I have written a module to save data to binary file . I have designed a structure and put information in that and save it to file . I save multiple such records one after other. I use fwrite , fflush instructions.
The module is working fine. I have saved near about 35 such files. But in one file , the module has saved Blank Records. The file size if perfect but the file is totally blank. It has happened for only one file but need to know the reason.
In the usual case, its an easy problem. But it gets tricky in my case, since I am working with numbers up to 30 digits, unable to store them in any int, long, long long. Due to this obstacle, the user inputs a number and each digit is stored in my array individually.
I need these commas to print as I am cout the array. This means I only have array length to work with.
I want to use modulus, but I'm not sure how this would work. I have:
void prArray(int Array[], const int arrSize) { int mod = arrSize % 3; int remainingSize = arraySize; int counter = 0; for(int i=0; i <= arrSize; i++){ remainingSize--;
[Code] ....
Which outputs the first digits correctly, but leaves 4 digits at the end: 235423452345 -> 23,542,345,2345
I'm doing a project that takes in a input file with Quarterback statistics. It has their name, team, completions, sacks, touchdowns, etc. It has 16 different variables in all (17 if you count first/last name as two). So I'm trying to read them and I can't figure out how to jump to the new line after it's read the file and put the information in the variables I've created.
That's the program I've written. The loop keeps displaying the first line of the file over and over. How can I get it to go to the second line, then the third, then fourth, etc? I need it to display all the lines of the file until it reaches the end of the file.
Now I would like to extract the data inside these comment tags and insert into excel sheet. Need to extract the comments in the xml tags shown in the able format? For example I want the value inside the <Autor> tag.
I'm building a simple little program for minecraft to reduce the repetitiveness, I'm using getpixel, it's slow, but i only need to grab about 6-12 pixels.
but the problem is, I can get the pixel data if I capture from the entire desktop display, but as soon as I tell it to grab from the active window (wich goes MUCH faster) it doesn't return any colour value's.
I'd rather not have to use getDIBits or program in java or anything since I want to keep it fairly kiss, and if it can't be done, then.. ah well, I'll just grab from the entire desktop, speed isn't to much of an issue, but it'll be a pain to keep the window at the same place.
Code: #include <Windows.h> #include <iostream> using namespace std; // vvv Ignore this, it's just used for retrieving the handle of a window without giving the full window name vvvv struct results {
I am trying to write a loop that will iterate through a char array in C and pull the IP addresses and test them to see if they respond. My ultimate goal is to have the first one that responds returned in the function, but the loop is not running correctly. It will run through right the first time, but then will start over again.

I was attempting something weired with address to move data around when I discovered that the size of the array is not what I expected. I am passing this structure as &Users to a function that declares it as a void *, then I can deal with chunks of data (memmove) and not have to worry about index or things like that. However...sizeof is returning something I do not understand.
