Command line parameters in C are specified after the program name on the system command line, and these parameter values ​​are passed to the program during program execution.

argc and argv are the two parameters that can be passed to the main function.

int main(int argc, char *argv[]){
   //Code
   return 0;
}

   }
   return 1;
