But that's ugly and complicates updating. I suppose the brute-force way to accomplish the above goal would be to make two copies of the Google Chrome application bundle under the respective names.

In other words, I needed two regular Mac applications, regChrome for normal browsing and altChrome to use the special profile, to be easily started by keying ⌘-space to bring up Spotlight, then 'reg' or 'alt', then Enter. I wanted to be able to start them from Spotlight, as is my habit for starting Mac apps.

Single argument in quotes separated by space : When the above code is compiled and executed with a single argument separated by space but inside single quotes, it produces the following output.I wanted to have two separate instances of Chrome running, each using its own profile. Single Argument : When the above code is compiled and executed with a single argument separated by space but inside double quotes, it produces the following output. Following Are The Command Line Arguments Passed. 
Three arguments : When the above code is compiled and executed with a three arguments, it produces the following output. No Extra Command Line Argument Passed Other Than Program Name Without argument: When the above code is compiled and executed without passing any argument, it produces following output. Note : You pass all the command line arguments separated by a space, but if argument itself has a space then you can pass such arguments by putting them inside double quotes “” or single quotes ”. argv points to the first command line argument and argv points last argument. They are used to control program from outside instead of hard coding those values inside the code. They are parameters/arguments supplied to the program when it is invoked. Note : Other platform-dependent formats are also allowed by the C and C++ standards for example, Unix (though not POSIX.1) and Microsoft Visual C++ have a third argument giving the program’s environment, otherwise accessible through getenv in stdlib.h: Refer C program to print environment variables for details. Argv is the name of the program, After that till argv every element is command -line arguments. 
If argc is greater than zero,the array elements from argv to argv will contain pointers to strings. argv(ARGument Vector) is array of character pointers listing all the arguments. The value of argc should be non negative. So if we pass a value to a program, value of argc would be 2 (one for argument and one for program name) argc (ARGument Count) is int and stores number of command-line arguments passed by the user including the name of the program. To pass command line arguments, we typically define main() with two arguments : first argument is the number of command line arguments and second is list of command-line arguments. 
Command-line arguments are given after the name of the program in command-line shell of Operating Systems. We can also give command-line arguments in C and C++. It is mostly defined with a return type of int and without parameters : The most important function of C/C++ is main() function.
