Command Line Arguments - C Programming

To illustrate the number of arguments

#include <stdio.h>

main (int argc, char argv[])

{

if(argc ==2)

printf("Argument supplied is %s\n", argv[1]);

else if(argc>2)

printf("Too many arguments supplied \n");

else

printf("One Argument expected \n");

}

EXPLANATION: The argument argv[0] is the name of the program invoked, which means that *argv[1] is a pointer to the first argument supplied and *argv[n] is the last argument. If no arguments are supplied, arge will be one. Thus for n arguments, arge will be equal to n+1. The program is called by the command line c:\TC sample arg1 ←┘
