How you write code

closed account (EwCjE3v7)
Hello there I was wondering how you guys write your code, use the following template(you may edit), and this is my format

#include <istream>
using std::cout using std::endl; using std::cin;

1
2
3
4
5
6
7
8
9
10
11
12
 
int main()
{
   int x = 0; // test comment
   int y[2] = {1, 2};
   
   cin >> x;
   
   for (int z = 2; z != 10; ++z) {
      cout << z << " times" << endl;
   }
}


How would you write this code?

static_assert(__clang__ && __cplusplus >= 199711L, "Your compiler is not supported.");

#include <iostream>
/// Triple slash to include in auto-generated documentation
int main()
{
   // test comment (two slashes to exclude from auto-generated documentation)
   int x = 0;
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunused-variable"
   auto y = {1, 2};
#pragma clang diagnostic pop
   std::cin >> x;
   for (int z = 2; z != 10; ++z)
   {
      std::cout << z << " times\n";
   }
   std::cout << std::endl;
}


* Reason being that I'm trying to force as many people as possible to switch to the obviously superior cross-platform compiler. :)

#include <iostream>
#include <vector>

int main()
{
	int x = 0; //test comment
	std::vector<int> y = {1, 2};
   
	std::cin >> x;
   
	for (int z = 2; z < 10; ++z)
	{
		std::cout << z << std::endl;
	}
}

My C++ is rusty. I honestly been spending too much time doing UnrealScript. I hope in UE4 the C++ code support is not going to be too Unreal Engine specific or far off from actual C++ code.

So I'd probably write that code like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
 
int main() {

    //test comment
    int x = 0;
    int y[2] = { 1, 2 };

    std::cin >> x;

    for(int z = 2; z < 10; z++) {
        std::cout << z << std::endl;
    }

}


And if it was longer then I'd probably add in "using namespace std;" at the top.

    {
         std::stringstream ss;

    using namespace std; //namespace for only this function.
    int an_int(0);
    int arr[2] = {1, 2};
    
    {
         string temps("");
         cin.rdbuf()->in_avail(); /*remove anything in the buffer.  We want to make sure that the user 
                                enters somthing*/

         cin>> temps;
         an_int = conv<string, int>(temps);
    }
    for(short x = 2; x < 11; x++) cout<< x<< " "<< ((x != 1) ? "times" : "time")<< endl;

#include <iostream>

int main(){
   std::cin.get();

   const int n = 10;
   for(int K=2; K<n; ++K)
      std::cout << K << " times\n";

   return 0;
}

It really depends on what I'm doing and whether I'm being lazy or not. I use std::, but if I'm being lazy (testing something) I just do using namespace std;
