So, today I played around a little with my main function and decided to print out the argv and argc arguments in the main function.
This resulted in the following being printed out :
Commandline argument amount : 1.
1. /Users/name/Library/Developer/Xcode/DerivedData/Playground-bdassylsrksorocyjtssfnwfbkpg/Build/Products/Debug/Playground
Input anything to continue.
a
Program ended with exit code: 0
After the '1.' it prints out the command line argument, my question is why does it have that command line argument? And what is it used for?
Here's the code I used for this little program :
#include <iostream>
int main(int argc, const char* argv[]) {
std::cout << "Commandline argument amount : " << argc << "." << std::endl;
for (int i = 0; i < argc; i++)
{
std::cout << std::endl;
std::cout << i + 1 << ". " << argv[i] << std::endl;
}
std::cout << std::endl;
std::cout << "Input anything to continue." << std::endl;
std::string inpt;
std::cin >> inpt;
return 0;
}
