The argument passed to the main() function while executing the program is known as command line argument. For example:
main(int count, char *args[]){
//code to be executed
}
Command-line arguments are inputs provided to a program when executing it through the command line or terminal. They allow users to customize the program’s behavior by passing values or options. Arguments are accessed within the program using language-specific variables or functions. For example, in C++, the main function accepts parameters argc (argument count) and argv (argument vector). These parameters hold the number and actual values of the command-line arguments, respectively. Programmers can utilize command-line arguments to make their programs more versatile and adaptable.
