Here it is:
Rewrote the substring() function as compared with the original version which may only handle string array specifically.
I came to the dead corner of my knowledge on string pointer in C: How to get the string length when you dynamically allocate the memory space for it? Or after you allocate the memory of a string pointer, how to get the string length?

Reason: Add more information.
void main()
{
int a={1,2,3,4,5,6,7,8,9,10};
int *p=a;
int *q=&a;
cout<<q-p+1<<endl;
}
The output is 10, how?
if we give cout<<q it will print the address, value won't print....
if we give cout<<p it will print the address, value won't print....
p has the base addr; q... (1 Reply)

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

Hi guys,
Besides the points bellow, what would best practices for scripting be ?
1) set the PATH
2) unset the current environment (set -u ?)
3) (re)set the IFS to default value - space (IFS="" <- is this correct ?)
