Command Line Arguments in C

Command line arguments can be used to pass the input to the C program through command line.

Below screen shot shows how to execute the program with command line arguments using gcc in windows system.

We have sent one argument to the program – "sagar Salunke".

Program prints the length of the argument that we have passed.

#include <stdio.h>

#include <string.h>

int main (int c, char *arg[])

{

if (c < 2)

{

      printf("too less arguments");

      return -1;

}

 printf("Number of command line arguments - %d \n" , c);

 printf("Length of the argument is %d", strlen(arg[1]));

 

}
