We have seen in class how the main method of every Java program has a parameter, Stringl] args, which is an array of Strings. When a program is executed, this parameter is set to the arguments specified on the command line. In a C or C++ 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. i.e. int main(int argo, char "argy) { /" .. . "/ } . argc (ARGUment Count) is int and stores number of command-line arguments passed by the user including the name of the program. So if we pass a value to a program, value of argc would be 2 (one for argument and one for program name) . The value of argc should be non negative. . argv(ARGument Vector) is array of character pointers listing all the arguments. . If argc is greater than zero, the array elements from argv[0] to argv[argc-1] will contain pointers to strings. . Argv[0] is the name of the program , After that till argv[argc-1] every element is command -line arguments. The code below can print out the arguments:The code below can print out the arguments: / Name of program mainreturn.cpp #include using namespace std; int main(int arge, char"* argv) cout
