[ad_1] Try following code: #include<iostream> #include<cstring> using namespace std; #define CHAR_ARRAY_SIZE 8 int main() { char charArray[CHAR_ARRAY_SIZE] = {‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’, ‘7’, ‘8’}; int intArray[2]; for(int i = 0; i < CHAR_ARRAY_SIZE/4; i++) { char ch1 = (charArray[4*i+0] – ‘0’); char ch2 = (charArray[4*i+1] – ‘0’); char ch3 = (charArray[4*i+2] – ‘0’); … Read more
[ad_1] When writing test().xyz = xxx you first execute test which onbiously returns some instance of ArrayList (btw. you should consider to use List<T> instead nowadays, which is strongly typed and thus safes you from casting every element in your list to its actual type). Now You can of course do what you want with … Read more
[ad_1] You can use string.Format and string.Join combined var output = string.Format(“[{0}]”, string.Join(“,”, yourArray)); and then you just need to print output string anywhere you want. String.Format will provide you with possibility to wrap joined string with [ and ] without concatenating string manually. 5 [ad_2] solved How to print array in format [1, 2, … Read more
[ad_1] You can use this regex: ^6.{4}D Here, ^ is the start of the string, .{4} means any four characters. Online demo [ad_2] solved RegEX : Find match based on condition [closed]
[ad_1] In your C code there is a fault: To take input name you have to use scanf(“%s”,&name) instead of %c. To convert the code into C++,you just have to use cin & cout.Though it is allowed to use scanf & printf in c++.I have use string instead of char array….here is the sample code: … Read more
[ad_1] The idea that this will form an infinite loop is based on an assumption about how the variables will be laid out in memory. In particular, it assumes that because i is defined immediately after a, that it will also be allocated in memory immediately after a. That’s certainly not guaranteed, but it equally … Read more
[ad_1] Some Code char s[10]; snprintf(s, 10, “%05d”, 100); Which results in s contains “00100” 0 [ad_2] solved C: How to extend variable-length strings to set length [closed]
[ad_1] The answer is: YOU CAN’T. Alain Knaff, who is the writer of linux kernel says; And i Quote This is Linux, not Windows, and Linux doesn’t have any bugs which would allow you to do this. There is a reason, after all, why more and more >people are ditching Windows, and using Linux. Ofcourse, … Read more
[ad_1] Ok your question seems to be particularly unpopular… just for info, have a look at http://en.wikipedia.org/wiki/Operators_in_C_and_C%2B%2B The operator you are looking for is && but I should not tell you this since in fact as downvotes testify… your question is a bit lazy! I also know that sometimes when you are a noob it … Read more
[ad_1] An assignment operator with signature Fraction operator=(const Fraction &newfraction) has to be a member function. A friend function is not a member. So the numbers of parameters don’t match the 2 needed for assignment. Remove the friend and make sure it is declared as a member function. struct Fraction { Fraction& operator=(const Fraction &newfraction) … Read more
[ad_1] To start you off, try this foundation: #include <string> #include <iostream> using std::string; using std::cout; using std::endl; using std::cin; int main(int argument_count, char * argument_list[]) { std::string filename; if (argument_count < 2) { filename = “You didn’t supply a filename\n”; } else { filename = argument_list[1]; } cout << “You want to open ” … Read more
[ad_1] There are 4 or 5 constructors in person. The 3 you defined yourself, plus the compiler-generated copy constructor. If C++11 is used, specific rules determine whether or not a move constructor will be generated for you, see here and here. 2 [ad_2] solved How many constructors are in the person class above?
[ad_1] there can ba multiple values that match the condition – Dictionary<int, decimal> dict = new Dictionary<int,decimal>(); dict.Add(1, 392.3m); dict.Add(2, 612m); dict.Add(3, 981m); dict.Add(4, 344.23m); List<int> Result = dict.Where(x => x.Value < 400).Select(x => x.Key).ToList(); 0 [ad_2] solved How can you select and filter dictionary keys based on their values using Linq?
[ad_1] Assuming the vector has 5 elements: #include <chrono> #include <thread> /* introduced with c++11, make sure your compiler is up to date and is set to compile c++ with this version of the STL and standard */ for (int i = 0; i < count; ++i) { cout << vector[count] << endl; std::this_thread::sleep_for(std::chrono::seconds(1)); } … Read more
[ad_1] This isn’t a choice of Qt, but the way proper design in C++ works. -> dereferences a pointer to an object to access a member of it. Passing a pointer around tends to be the cleanest method of access to an object. [ad_2] solved Why does Qt use arrow syntax? [closed]
