Question

15:9: error: incompatible types when assigning to type ‘char[3]’ from type ‘char *’

#include <stdio.h>


int main(int argc, char *argv[])
{

     char servIP[3];
     int servPortNum;
     if(argc<3)
     {
         printf("Usage: clientApp servIP servPortNum\n");
     }

     servIP = argv[1];
     servPortNum = atoi(*argv[2]);


}

Answer 1

strncpy (servIP, argv [1], sizeof (servIP) - 1);
servIP [sizeof (servIP) - 1] = 0;

But are you sure servIP is big enough for an IP address?
