| | there are 2 common ways to loop through a vector 1: [CODE] vector<int> myvec; // let's assume it's initialized for(int i = 0; i != myvec.size( ); i++) { // code // access by 'myvec[i]' } [/CODE] 2: [CODE] vector<int> myvec; // let's assume it's initialized for(vector<int> :: iterator i … |
| | basically i have a header full of function prototypes(util.h) and a cpp file with the functions body [CODE] // util.h #include <ctime> uint32_t GetTime( ); uint32_t GetTicks( ); // util.cpp #include <util.h> uint32_t GetTime( ) { return GetTicks( ) / 1000; } uint32_t GetTicks( ) { return clock( ); } …  |
