i working on learning algorithm, , giving inputs command line using input file, following:- c:\user\document> sbp < input.txt

but want input file multiple times(not definite) till training error not below threshold, how can it..

you can either give multiple times on command line, 

 ./command.exe input.txt input.txt input.txt

or give once 

 ./command.exe input.txt

and open multiple times when need 

int main(int argc, char **argv) {     (int = 0; < 3; ++i) {         std::ifstream f(argv[1]);         // process input     } }
