passing filename as arguments in c++
I have to pass four different text files in an argument in开发者_JS百科 c++ program. How do i pass??
int main(int argc, char ** argv) {
std::vector<std::string> args(argv, argv+argc);
for (size_t i = 1; i < args.size(); ++i) {
std::string const & aFileName = args[i];
// Do something with aFileName
}
}
I assume you mean on the command line. When main
is defined as
int main(int argc, char *argv[])
argc
is the count of arguments and argv
contains them. The first arg in the array will be the name of the process and the others are the arguments passed to it.
