You can place a definition int var; after main(), it will work.

Re: [algogeeks] what is the error???
@sanju, if u declare a variable with extern, at compile time its defn is nt
looked for, rather @ link time corresponding defn is looked for by the
linker. nd if the defn is nt ther, it will raise a linker error, as in case
of this prog
@rahul, ya off course, for a variable to be global it hs to be defined at
file scope.

Re: [algogeeks] What is the error in the following function
Variable start and hex_buf point to string constant, which can not be

Change:

[algogeeks] What is the error in the following function
Hi All,
Can you please point me to the error in the following function. It gives
segmentation fault.
int main()
{
char *start = "12.12.12.12.12976665176069214";
char *hex_buf = "65003a0a";
unsigned short i, j = 0;
int new_len2 = strlen(hex_buf);
for (i = 0; ((j+1) < new_len2); i+=2,j+=2)
{
start[i] = hex_buf[j];
start[i+1] = hex_buf[j+1];
}
}
Thanks,
