Question

Properly format the following code such that the scope of each code block is properly indented. #include #include using namespace std; void method2(int& mult){ mult *= 2; } void method1(int& count){ count += 2; } int main(){ chrono::time_point start; chrono::time_point end; int mult = 1, count = 0; int nums[] = {1,2,3,4,5,6,7}; int choice; cout << "Enter your choice (1 or 2): "; cin >> choice; const int maxReps = 31; switch(choice){ //method 1 case 1: start = chrono::system_clock::now(); for(int i = 0; i < maxReps; i++) method1(count); end = chrono::system_clock::now(); break; //method 2 case 2: start = chrono::system_clock::now(); for(int i = 0; i < maxReps; i++) method2(mult); end = chrono::system_clock::now(); break; //etc on cases default: break; } chrono::duration elapsed = end-start; cout << "Total time in seconds: " << elapsed.count() << endl; cout << "count = " << count << " mult = " << mult << endl; }

Answer 1

#include <iostream>
#include <chrono>

using namespace std;

void method2(int& mult)
{
   mult *= 2;
}

void method1(int& count)
{
   count += 2;
}

int main()
{
  using namespace std::chrono;

   chrono::time_point start;
   chrono::time_point end;
   int mult = 1, count = 0;
   int nums[] = {1,2,3,4,5,6,7};
   int choice;
   
   cout << "Enter your choice (1 or 2): ";
   cin >> choice;
   const int maxReps = 31;
   
   switch(choice)
   {
      //method 1 
      case 1: start = chrono::system_clock::now(); 
            for (int i = 0; i < maxReps; i++)
               method1(count);
            end = chrono::system_clock::now(); 
            break; 
      
      //method 2
      case 2: start = chrono::system_clock::now();
            for(int i = 0; i < maxReps; i++)
               method2(mult);
            end = chrono::system_clock::now();
            break;
      
      //etc on cases
      default: break;
   }
   
   chrono::duration elapsed = end-start;
   cout << "Total time in seconds: " << elapsed.count() << endl;
   cout << "count = " << count << " mult = " << mult << endl;

   return 0;
}

Note: The complete code is included with proper indentation.
