This assignment begins software tools and techniques for structuring complex programs. Use it to become familiar with these facilities, and ensure you use the speci?ed concepts in your assignment solution.
1. Run the following C++ program with and without preprocessor variable POSTFIX de?ned.
#include using namespace std;extern "C" int atoi( const char *str );struct Node {int i, j, k;Node() {}};int main( int argc, char *argv[ ] ) {int times = 10000;switch ( argc ) {case 2:times = atoi( argv[1] );} // switchvector v( 10000 );vector::iterator vi;volatile int j = 0; // ignore, prevent loop eliminationfor ( int i = 0; i < times; i += 1 ) {for ( vi = v.begin(); vi != v.end();#ifdef POSTFIXvi ++#else++ vi#endif) {j += 1; // ignore, prevent loop elimination}}
Compare the two versions of the program with respect to performance by doing the following:
% time ./a.out
3.21u 0.02s 0:03.32 100.0%
(Output from time differs depending on your shell, but all provide user, system and real time.) Compare the user time (3.21u), which is the CPU time consumed solely by the execution of user code (versus system and real time).
