Using char array arguments

Part of ArraysCategory

Description

A basic way to use the 'args' variable in the 'main' function.

Example

/*
to use, type:
[program name] -p [string to print]

This could be more complicated, but this'll give you an idea on
how to use arguments in your program.
*/

int main(char[][] args)
{
    // check to make sure that the number of args is correct
    if(args.length < 2) // the first argument is the program name...
    {
        printf("No arguments given.\n");
        return 0;
    }

    for(int i = 0; i < args.length;i++)
    {
        if(args[i][0 .. 2] == "-p")
        {
            for(int ii = i+1; ii < args.length;ii++)
            {
                printf("%.*s ", args[ii]);
            }
            printf("\n");
        }
    }
    return 0;
}
