I recommend using glob with this reusable wrapper. It generates a vector corresponding to file paths that fit the glob pattern:

#include 
#include 
using std::vector;

vector globVector(const string& pattern){
    glob_t glob_result;
    glob(pattern.c_str(),GLOB_TILDE,NULL,&glob_result);
    vector files;
    for(unsigned int i=0;i

Which can then be called with a normal system wildcard pattern such as:

vector files = globVector("./*");
