I am reading data from a text file into a program. I am well aware of the subtle distinctions in the mode of data input/entry when using the stream extraction operator, the get() function, and the getline() function.
My problem is that all of them do not read and/or store the newline character alongside the data read!
Any function that reads and stores data and the terminating newline character together??
I want to examine every packet of a pcap trace file and if packet n+1 source address == packet n destination address && packet n+1 destination address == packet n source address i want to get the time between those 2 packages.
Problem: I can't compare the ipv6 adresses of src and destination.
comparing src and src is no problem. dst with dst as well
if i try to compare these adresses i will never get a match. But i use a trace file with much matches. Do i need a offset in pkt_ptr? I saw some examples which deals with it.
Code:
uint32_t* test = (uint32_t*)ipv6_dst; for (uint32_t j=0;j<sizeof(ip_hdr->ip6_dst);j++) { printf ("%x", *(test+j)); } printf ("
#include <iostream> #include<fstream> int decryption(int); int multiply(int,int[][2]); using namespace std; main(){ int n; ifstream inFile; inFile.open ("out.txt");

I was trying to store numbers read from a text file into 2D array but I am getting the error above.here is where the error occurs:
I have a base class Building. Then come its children classes - Commercial Building and Residential Building. The third level is composed of Apartment and House classes, both inherit from Residential Building.
I need to create an array of 20 elements that will store info about all these different types of buildings(Commercial Building,Residential Building,Apartment, House). How should I proceed?
I want to create filenames such as Query.student.1.bin and save them in an array. I have no problem when I don't include a "." between student and number "1" but as I add a "." there my code does not run. ( it does complie but crashes during the run)
for(int i = 0 ; i < SIZE ; i ++) { scanf("%d" , & selection[i]); srand((unsigned) time(&t)); draw[i] = rand() % 50; //feeling could be a problem with this line of code :::::
}
is it possible to do this. i am trying to get 6 different numbers stored into 6 elements of an array . this is the piece of the code i think there is a problem with. ie my program scans the numbers and then crashes at this point so think it could be something to do with the commented line?
For some reason the integer array, arr[100][50], declared in main is not storing the correct values when passed through the function charArrayToIntArray.
I made an output right in the function to show how the array is not keeping the proper values, although when I output the array from within the loop in the function, it shows the correct values.
here is my problem given below Input values (say 10) from user in array, if the value is even then place at even index else at odd index. Then how could i solve this problem?
The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
I'm trying to read in a file and store it in an array that is dynamically allocated of a struct (which I'm not sure how to do), then parse each line using strtok() from string.h. The idea is to separate the lines by date, subject, time, etc.
Since the array is a dynamically allocated of typdef struct, it's sorted by the date of each struct, with an intial size of 25. But whenever the array needs to be resized, it should be doubled.
I have been dealing with this problem for quite some time, I've been assigned to develop a program that can store products' information within structures (the number of products is undefined). I thought I should use an array of structures, but I don't know how to declare it properly. This is what I thought would work:
struct product { string name; string in_stock; float sale_cost; int id; } prod [n]; //n being the undefined number of products the user will register/delete/modify
I already saw an example of array of structures, but it uses a defined number.
I need to read input from a file , which contains multiple sentences of varying lengths. After each new line char, i need to store that sentence into an array.
I just started learning about pointer and reference. * and &
The assignment is " Write a program that stores the following numbers in the array named miles:15,22,16,18,27,23, and 20. Have your program copy the data stored in miles to another array named dist, and then display the values in the dist array. YOur program should use pointer notation when copying and displaying array elements.
And this is what i have so far. But there is an error. I highlighted it with red. It says it's incompatible...
#include <iostream> using namespace std; const int arraynumb = 7; // declaration of keys: number of characters of keys void copyfunc(int *[], int); // function initialized int main() { int miles[arraynumb] = {15, 22, 16, 18, 27, 23, 20};
I am trying to use C# with C++, two different applications that work together.
In C# it is easy to get a byte array out of a string, by just using Encoding.Default.GetBytes(of-this-string);
I can pass bytes to my C++ program by just writing in the embedded resources. But this won't allow strings, as far as I know it can only be a byte array. C++ reads the embedded resources a LPBYTE.
So I try to send the string or message in byteform.
However the problem in C++ is that there is no Encoding.Default.GetString(xxx)
Would there be any other ways to send a message/sentence in bytearrayform and request it in C++ back to the original string?
