The command line arguments are handled using main() function arguments where argc refers to the number of arguments passed, and argv[] is a pointer array which points to each argument passed to the program. Following is a simple example which checks if there is any argument supplied from the command line and take action accordingly −
When the above code is compiled and executed with single argument, it produces the following result.
When the above code is compiled and executed with a two arguments, it produces the following result.
When the above code is compiled and executed without passing any argument, it produces the following result.
It should be noted that argv[0] holds the name of the program itself and argv[1] is a pointer to the first command line argument supplied, and *argv[n] is the last argument. If no arguments are supplied, argc will be one, and if you pass one argument then argc is set at 2.
