C++ Keeping track of how many seconds has passed since start of program

Question

I am writing a program that will be used on a Solaris machine. I need a way of keeping track of how many seconds has passed since the start of the program. I\'m talking very sim

Answer 1

Use std::chrono.

#include 
#include 

int main(int argc, char *argv[])
{
   auto start_time = std::chrono::high_resolution_clock::now();
   auto current_time = std::chrono::high_resolution_clock::now();

   std::cout << "Program has been running for " << std::chrono::duration_cast(current_time - start_time).count() << " seconds" << std::endl;

   return 0;
}

If you only need a resolution of seconds, then std::steady_clock should be sufficient.
