- An array containing the program compilation flags
- An array containing the program command line arguments
- An array of size
argc
Solution
argv is an array containing the program command line arguments. It is used in the main function in C and C++ programming languages. The name argv stands for 'argument vector'.
When you run a program, you can pass command line arguments to it. These arguments are stored in the argv array. The first element of the argv array (i.e., argv[0]) is the name of the program itself, argv[1] is the first command line argument passed to the program, argv[2] is the second command line argument, and so on.
The size of the argv array is stored in argc, which stands for 'argument count'. argc gives the number of command line arguments passed to the program, including the name of the program itself. So, if no command line arguments are passed to the program, argc will be 1 (as the name of the program is considered as a command line argument).
