Need help in character pointer
Hi,
I am trying to divide my input to different type of out puts for some other use.
ex: logical_name : jkl00001
expected out put : model=jkl and num=00001
here is the code i actually written
/*******************************************************************/
void update_new_logical_name(char *logical_name)
/**********************************************************************/
{
int next=0,ret=0,n;
char model[4];
int num[6];
char *name;
name=logical_name;
for(n=0;n<3;n++)
{
model[n]=name[n];
}
model[4]='\0';
for(n=3;n<8;n++)
{
num[n-3]=name[n];
}
num[6]='\0';
#ifdef DEBUG
printf("\n\nmodel== '%s',number=='%d'\n",model,num);
#endif
}
by using the above code i am not able to print anything .num displays some address and model displays nothing.
Some body please correct me
I need it urgently.
Thx,
jagan

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:

{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)
