Question

The main function goes like this:

void main( int argc, char** argv ){
    // validate that an input was specified
    if( argc != 2 )
    {
        printUsage();
        return;
    }

    if( !strcmp(argv[1], "train") ) learn();
    else if( !strcmp(argv[1], "test") ) recognize();
    else
    {
        printf("Unknown command: %s\n", argv[1]);
        printUsage();
    }
}

When I execute the program the console disappears as soon as it appears.

Thanks so much for your patience and help! 🙂

This program doesn’t use user input, but uses program arguments.

This program need 1 input argument that you can set that in these ways:

1. open cmd, change directory(cd) to the where the exe file exists, and run the program with arguments. e.g. main.exe train
2. on vs2010, go to project properties, under “Configuration Properties” find Debugging and set the “Command Arguments” to what argument you want.
