From the man page: The realloc() function changes the size of the memory block pointed to by ptr to size bytes. So instead of: int *newbuffer = (int*) realloc (stacky, size); you probably want int *newbuffer = (int*) realloc (stacky, size * sizeof(int)); BTW: No need for cast when using malloc and friends. See Do … Read more
When i is 1, you print it with the printf statement. Then i gets incremented (via the ++ operator in your printf statement). Then i /= 2 is performed, which results to i = 2 / 2 which results to 1. This satisfies your condition i >= 1, making it an infinite loop. solved What … Read more
The first one is much cleaner and easier to read. C# coders will be used to seeing it done that way. solved best approach check string null and empty C# [closed]
You shouldn’t be using typedef here. That means you are aliasing those types to the names you specify, not creating instances of them. You should do this instead: //create a vector of functions which take no arguments and return an int std::vector<std::function<int()>> functionvector {}; //implicitly converts the function pointer to a std::function<int()> and pushes functionvector.push_back(function1); … Read more
int x; while(cin>>x) { store the number one by one } //process Simply do it this way. Store the numbers in the array. Or you can do it this way- string s; getline(cin,s); std::stringstream myss; myss<<s; std::string t; int x; std::vector<int> v; while(std::getline(myss,t,’ ‘)) { if(std::stringstream(t)>>x) { // store x in an vector. v.push_back(x); } … Read more
Alternatively to what’s suggested here, you fix the problem in the header file without actually moving the definition of PCLIENT into the header: … struct _client; … // Accept Client. BOOL AcceptClient(struct _client* current_client); … // Receive data from client. BOOL recv_data(struct _client* current_client, char *buffer, int size); … // Send data. BOOL send_data(struct _client* … Read more
You haven’t converted it correctly. The VB code selects DataGridViewRows, the C# code selects ints. You want to take N rows. VB.NET supports Enumerable.Take directly in the LINQ query, C# does not support it. So i’d use method syntax in C#. So this works as desired (don’t translate Dim with dynamic but var): int takeRows … Read more
If your compiler is up to date with the standard: std::list<std::vector<std::string>> lst; for ( auto& vec : lst ) // Iterate through all std::vector’s for ( auto& str : vec ) // Iterate through all std::string’s std::cout << str << std::endl; // str is your std::string 0 solved Can we put vector to the list … Read more
1) if (selection >= ‘a’ && selection <= ‘h’) The user could have caps lock pressed, so consider A~Z also 2) (in my opinion) Quit should be at the start of logic. 3) You can use switch(selection) instead. dafault: Invalid Input. Try again. 4) Put your output in a function and pass the variables to … Read more
To calculate a power in C, the best way is to use the function pow(). It takes two double arguments: the first is the number that will be raised by the power, and the second argument is the power amount itself. So: double z = pow(double x, double y); Then the result will be saved … Read more
I believe the technique you’re looking for is answered in this article: c++: How to catch mouse clicks wherever they happen. What you would do is create a global mouse hook and use it to determine whether a user has clicked in a text box. If they have, you can pop up your keyboard and … Read more
It does not work that way, you better use the c++ code only as a description of requirements. If that’s not an option, then I can only provide you with the following hint: // have a create function for you Hash object (I’m trying to simplify here) public class Hash { static const int C= … Read more
%%.2f needs an extra % symbol to make the final .2f into a format rather than the string literal that’s being displayed. Secondly realloc is intended to resize a previously calloc-ed array in memory. solved Source code using a structure pointer
I found the solution: Add a parent group to the first group and limit the number of rows per page using the following expression =CEILING(RowNumber(Nothing)/13) (where 13 is the number of rows per page) add a footer to this group that will calculate your total per page(subtotal) using the sum function on one of the … Read more
You’ll probably need a vector like Soren mentioned. If you’re trying to get some averages for all employees (which that’s what I assume you’re trying to do), then let’s say we’re going to try and get an average for gross pay. You’ll need a vector global, like such: #include <iostream> #include <fstream> #include <iomanip> #include … Read more
